Official Baseball Rules

This code of rules governs the playing of baseball games by professional teams of Major League Baseball and the leagues that are members of the National Association of Professional Baseball Leagues. We recognize that many amateur and non-professional organizations play their games under professional rules and we are happy to make our rules available as widely as possible. It is well to remember that specifications as to fields, equipment, etc., may be modified to meet the needs of each group. Money fines, long-term suspensions and similar penalties imposed by this code are not practicable for amateur groups, but officers and umpires of such organizations should insist on strict observance of all the rules governing the playing of the game. Baseball not only has maintained its position as the National Game of the United States, but also has become an International Game being played in more than 100 countries. The popularity of the game will grow only so long as its players, managers, coaches, umpires and administrative officers respect the discipline of its code of rules.

FOREWORD
This code of rules governs the playing of baseball games by professional
teams of Major League Baseball and the leagues that are members of the
National Association of Professional Baseball Leagues.
We recognize that many amateur and non-professional organizations play
their games under professional rules and we are happy to make our rules
available as widely as possible. It is well to remember that specifications as
to fields, equipment, etc., may be modified to meet the needs of each group.
Money fines, long-term suspensions and similar penalties imposed by this
code are not practicable for amateur groups, but officers and umpires of such
organizations should insist on strict observance of all the rules governing the
playing of the game.
Baseball not only has maintained its position as the National Game of the
United States, but also has become an International Game being played in
more than 100 countries. The popularity of the game will grow only so long
as its players, managers, coaches, umpires and administrative officers
respect the discipline of its code of rules.

The Playing Rules Committee, at its December 1977 meeting, voted to
incorporate the Notes/Case Book/Comments section directly into the
Official Baseball Rules at the appropriate places.  Basically, the Case
Book interprets or elaborates on the basic rules and in essence have the
same effect as rules when applied to particular sections for which they
are intended.
This arrangement is designed to give quicker access to any written lan-
guage pertaining to an Official Rule and does not require a reader to
refer to different sections of the Official Baseball Rules book in con-
sidering the application of a particular rule.
IMPORTANT NOTES
(1)
The Playing Rules Committee, at its December 2014 meeting, voted to
reorganize and recodify the Official Baseball Rules into a more logical
and organized manner.  No wording or language was changed (other
than the amendments made for that year); only the order and place-
ment of the rules were modified.  In this edition Comments to the
Official Rules are highlighted in a shaded box rather than being
printed in smaller typeface as had been the case in prior to 2015.

The Official Playing Rules Committee made the following changes that
will be in effect for the 2018 season:
 Amended Rule 4.08(c) to change the length of time between doublehead-
ers.
 Amended Rule 5.07(b) regarding warm-up pitches that a pitcher may
throw.
 Amended Rule 5.09(c)(1) Comment regarding a runner who takes a "fly-
ing start" from behind a base when tagging up; namely, such violation is
now considered an appeal play.
 Re-titled Rule 5.10(l) and amended Rule 5.10(l) Comment regarding
warm-up pitches when a substitute pitcher enters a game in the situation
described in the last paragraph of Rule 5.10(l) Comment.
 Established new Rule 5.10(m) limiting the number of mound visits per
game.
 Amended Rule 6.01(a)(5) Comment to clarify that a runner who is return-
ing to his last legally touched base after being put out is considered the
same as a runner who continues to advance after being put out relative to
interfering with a subsequent play.
 Amended Rule 8.02(c) to set limits on when a ball/strike count may be
corrected.
 Amended Definitions of TermsSpectator Interference ("Interference,"
Part (d))to include additional situations when Spectator Interference
may be invoked.
In addition, an Index has been compiled and is located at the end of this
book.  Minor revisions were made to Diagrams #1, #2, and #3.

shall score one run for his team.
1.05 The objective of each team is to win by scoring more runs than the
opponent.
1.06 The winner of the game shall be that team which shall have scored,

2.00THE PLAYING FIELD
2.01 Layout of the Field
The field shall be laid out according to the instructions below, sup-
plemented by the diagrams in Appendices 1, 2, and 3.
The infield shall be a 90-foot square.  The outfield shall be the area
between two foul lines formed by extending two sides of the
square, as in diagram in Appendix 1 (page 153).  The distance from
home base to the nearest fence, stand or other obstruction on fair
territory shall be 250 feet or more.  A distance of 320 feet or more
along the foul lines, and 400 feet or more to center field is prefer-
able.  The infield shall be graded so that the base lines and home
plate are level.  The pitcher's plate shall be 10 inches above the
level of home plate.  The degree of slope from a point 6 inches in
front of the pitcher's plate to a point 6 feet toward home plate shall
be 1 inch to 1 foot, and such degree of slope shall be uniform.  The
infield and outfield, including the boundary lines, are fair territory
and all other area is foul territory.
It is desirable that the line from home base through the pitcher's
plate to second base shall run East-Northeast.
It is recommended that the distance from home base to the backstop,
and from the base lines to the nearest fence, stand or other obstruc-
tion on foul territory shall be 60 feet or more.  See Appendix 1.
When location of home base is determined, with a steel tape meas-
ure 127 feet, 338 inches in desired direction to establish second
base. From home base, measure 90 feet toward first base; from sec-
ond base, measure 90 feet toward first base; the intersection of
these lines establishes first base. From home base, measure 90 feet
toward third base; from second base, measure 90 feet toward third
base; the intersection of these lines establishes third base. The dis-
tance between first base and third base is 127 feet, 338 inches. All
measurements from home base shall be taken from the point where
the first and third base lines intersect.
The catcher's box, the batters' boxes, the coaches' boxes, the three-
foot first base lines and the next batter's boxes shall be laid out as
shown in the diagrams in Appendices 1 and 2.

The foul lines and all other playing lines indicated in the diagrams
by solid black lines shall be marked with paint or non-toxic and
non-burning chalk or other white material.
The grass lines and dimensions shown on the diagrams are those
used in many fields, but they are not mandatory and each club shall
determine the size and shape of the grassed and bare areas of its
playing field.
NOTE:  (a) Any Playing Field constructed by a professional
club after June 1, 1958, shall provide a minimum distance of
325 feet from home base to the nearest fence, stand or other
obstruction on the right and left field foul lines, and a mini-
mum distance of 400 feet to the center field fence.
(b) No existing playing field shall be remodeled after
June 1, 1958, in such manner as to reduce the distance from
home base to the foul poles and to the center field fence below
the minimum specified in paragraph (a) above.
2.02 Home Base
Home base shall be marked by a five-sided slab of whitened rubber.
It shall be a 17-inch square with two of the corners removed so that
one edge is 17 inches long, two adjacent sides are 8 inches and
the remaining two sides are 12 inches and set at an angle to make a
point. It shall be set in the ground with the point at the intersection
of the lines extending from home base to first base and to third
base; with the 17-inch edge facing the pitcher's plate, and the two
12-inch edges coinciding with the first and third base lines. The top
edges of home base shall be beveled and the base shall be fixed in
the ground level with the ground surface. (See drawing D in
Appendix 2.)
2.03 The Bases
First, second and third bases shall be marked by white canvas or
rubber-covered bags, securely attached to the ground as indicated
in Diagram 2. The first and third base bags shall be entirely within
the infield. The second base bag shall be centered on second base.
The bags shall be 15 inches square, not less than three nor more
than five inches thick, and filled with soft material.

2.04 The Pitcher's Plate
The pitcher's plate shall be a rectangular slab of whitened rubber,
24 inches by 6 inches. It shall be set in the ground as shown in
Diagrams 1 and 2, so that the distance between the pitcher's plate
and home base (the rear point of home plate) shall be 60 feet, 6
inches.
2.05 Benches
The home club shall furnish players' benches, one each for the
home and visiting teams. Such benches shall not be less than
twenty-five feet from the base lines. They shall be roofed and shall
be enclosed at the back and ends.

3.02 The Bat
(a) The bat shall be a smooth, round stick not more than 2.61
inches in diameter at the thickest part and not more than 42
inches in length. The bat shall be one piece of solid wood.

Rule 3.02(c) to 3.03(f)
6
NOTE: If the umpire discovers that the bat does not con-
form to (c) above until a time during or after which the bat
has been used in play, it shall not be grounds for declaring
the batter out, or ejected from the game.
Rule 3.02(c): If pine tar extends past the 18-inch limitation,
then the umpire, on his own initiative or if alerted by the
opposing team, shall order the batter to use a different bat. The
batter may use the bat later in the game only if the excess sub-
stance is removed. If no objections are raised prior to a bat's
use, then a violation of Rule 3.02(c) on that play does not nul-
lify any action or play on the field and no protests of such play
shall be allowed.
(d) No colored bat may be used in a professional game unless
approved by the Rules Committee.
3.03 Player Uniforms
(a) All players on a team shall wear uniforms identical in color,
trim and style, and all players' uniforms shall include minimal
six-inch numbers on their backs.
(b) Any part of an undershirt exposed to view shall be of a uniform
solid color for all players on a team. Any player other than the
pitcher may have numbers, and /or letters, insignia attached to
the sleeve of the undershirt.
(c) No player whose uniform does not conform to that of his team-
mates shall be permitted to participate in a game.
(d) A league may provide that each team shall wear a distinctive
uniform at all times, or that each team shall have two sets of
uniforms, white for home games and a different color for road
games.
(e) Sleeve lengths may vary for individual players, but the sleeves
of each individual player shall be approximately the same
length, and no player shall wear ragged, frayed or slit sleeves.
(f ) No player shall attach to his uniform tape or other material of a
different color from his uniform.

widened, or deepened by the use of any materials or process what-
soever. The web of the mitt shall measure not more than five inches
from its top to the base of the thumb crotch. The web may be either
a lacing, lacing through leather tunnels, or a center piece of leather
which may be an extension of the palm connected to the mitt with
lacing and constructed so that it will not exceed the above men-

item being measured and follow all contours in the process.  The
glove shall not measure more than 13 inches from the tip of any
one of the 4 fingers, through the ball pocket to the bottom edge or
heel of glove.  The glove shall not measure more than 7  inches
wide, measured from the inside seam at base of first finger, along
base of other fingers, to the outside edge of little finger edge of
glove.  The space or area between the thumb and first finger, called
crotch, may be filled with leather webbing or back stop.  The web-
bing may be constructed of two plies of standard leather to close
the crotch area entirely, or it may be constructed of a series of tun-
nels made of leather, or a series of panels of leather, or of lacing
leather thongs. The webbing may not be constructed of wound or
wrapped lacing to make a net type of trap. When webbing is made
to cover entire crotch area, the webbing can be constructed so as to
be flexible. When constructed of a series of sections, they must be
joined together. These sections may not be so constructed to allow
depression to be developed by curvatures in the section sides. The
webbing shall be made to control the size of the crotch opening.
The crotch opening shall measure not more than 4  inches at the
top, not more than 5  inches deep, and shall be 3  inches wide at
its bottom.  The opening of the crotch shall not be more than 4

inches at any point below its top. The webbing shall be secured at
each side, and at top and bottom of crotch.  The attachment is to be
made with leather lacing, these connections to be secured. If they

dition.  The glove can be of any weight.  See Appendix 4 for dia-
gram of glove dimensions.
3.07 Pitcher's Glove
(a) The pitcher's glove may not, exclusive of piping, be white,
gray, nor, in the judgment of an umpire, distracting in any man-
ner. No fielder, regardless of position, may use a fielding glove

color different from the glove.
(c) The umpire-in-chief shall cause a glove that violates Rules

mended.
3.09 Undue Commercialization
Playing equipment including but not limited to the bases, pitcher's
plate, baseball, bats, uniforms, catcher's mitts, first baseman's
gloves, infielders' and outfielders' gloves and protective helmets, as
detailed in the provisions of this rule, shall not contain any undue
commercialization of the product. Designations by the manufac-
turer on any such equipment must be in good taste as to the size and
content of the manufacturer's logo or the brand name of the item.
The provisions of this Rule 3.09 shall apply to professional leagues

4.00GAME PRELIMINARIES
4.01 Umpire Duties
Before the game begins the umpire shall:
(a) Require strict observance of all rules governing implements of
play and equipment of players;
(b) Be sure that all playing lines (heavy lines on Appendices No. 1
and No. 2) are marked with lime, chalk or other white material
easily distinguishable from the ground or grass;
(c) Receive from the home club a supply of regulation baseballs,
the number and make to be certified to the home club by the
League President.  The umpire shall inspect the baseballs and
ensure they are regulation baseballs and that they are properly
rubbed so that the gloss is removed. The umpire shall be the
sole judge of the fitness of the balls to be used in the game;
(d) Be assured by the home club that at least one dozen regulation
reserve balls are immediately available for use if required;
(e) Have in his possession at least two alternate balls and shall
require replenishment of such supply of alternate balls as
needed throughout the game. Such alternate balls shall be put
in play when:
(1) A ball has been batted out of the playing field or into the
spectator area;
(2) A ball has become discolored or unfit for further use;
(3) The pitcher requests such alternate ball.
Rule 4.01(e) Comment: The umpire shall not give an alternate
ball to the pitcher until play has ended and the previously used
ball is dead. After a thrown or batted ball goes out of the play-
ing field, play shall not be resumed with an alternate ball until
the runners have reached the bases to which they are entitled.
After a home run is hit out of the playing grounds, the umpire
shall not deliver a new ball to the pitcher or the catcher until
the batter hitting the home run has crossed the plate.

(f ) Ensure that an official rosin bag is placed on the ground behind
the pitcher's plate prior to the start of each game.
(g) (4.14) The umpire-in-chief shall order the playing field lights
turned on whenever in his opinion darkness makes further play
in daylight hazardous.
4.02 Field Manager
(a) The club shall designate the manager to the League President
or the umpire-in-chief not less than thirty minutes before the
scheduled starting time of the game.
(b) The manager may advise the umpire-in-chief that he has dele-
gated specific duties prescribed by the rules to a player or
coach, and any action of such designated representative shall
be official. The manager shall always be responsible for his
team's conduct, observance of the official rules, and deference
to the umpires.
(c) If a manager leaves the field, he shall designate a player or
coach as his substitute, and such substitute manager shall have
the duties, rights and responsibilities of the manager. If the
manager fails or refuses to designate his substitute before leav-
ing, the umpire-in-chief shall designate a team member as sub-
stitute manager.
4.03 Exchange of Lineup Cards
Unless the home club shall have given previous notice that the
game has been postponed or will be delayed in starting, the umpire,
or umpires, shall enter the playing field five minutes before the
hour set for the game to begin and proceed directly to home base
where they shall be met by the managers of the opposing teams. In
sequence:
(a) First, the home manager, or his designee, shall give his batting
order to the umpire-in-chief, in duplicate.
(b) Next, the visiting manager, or his designee, shall give his bat-
ting order to the umpire-in-chief, in duplicate.
(c) As a courtesy, each lineup card presented to the umpire-in-
chief should list the fielding positions to be played by each

player in the batting order. If a designated hitter is to be used,
the lineup card shall designate which hitter is to be the desig-
nated hitter.  See Rule 5.11(a).  As a courtesy, potential substi-
tute players should also be listed, but the failure to list a poten-
tial substitute player shall not make such potential substitute
player ineligible to enter the game.
(d) The umpire-in-chief shall make certain that the original and
copies of the respective batting orders are identical, and then
tender a copy of each batting order to the opposing manager.
The copy retained by the umpire shall be the official batting
order.  The tender of the batting order by the umpire shall
establish the batting orders. Thereafter, no substitutions shall
be made by either manager, except as provided in the rules.
(e) As soon as the home team's batting order is handed to the
umpire-in-chief the umpires are in charge of the playing field
and from that moment the umpire-in-chief shall have sole
authority to determine when a game shall be called, suspended
or resumed on account of weather or the condition of the play-
ing field.  The umpire-in-chief shall not call the game until at
least 30 minutes after he has suspended play. The umpire-in-
chief may continue the suspension so long as he believes there
is any chance to resume play.
Rule 4.03 Comment: Obvious errors in the batting order,
which are noticed by the umpire-in-chief before he calls "Play"
for the start of the game, should be called to the attention of the
manager or captain of the team in error, so the correction can
be made before the game starts. For example, if a manager has
inadvertently listed only eight men in the batting order, or has
listed two players with the same last name but without an iden-
tifying initial and the errors are noticed by the umpire before
he calls "play," he shall cause such error or errors to be cor-
rected before he calls "play" to start the game. Teams should
not be "trapped" later by some mistake that obviously was
inadvertent and which can be corrected before the game starts.
The umpire-in-chief shall at all times try to complete a game.
His authority to resume play following one or more suspen-
sions of as much as 30 minutes each shall be absolute and he

shall terminate a game only when there appears to be no possi-
bility of completing it.
The Major Leagues have determined that Rule 4.03(e) does not
apply to any Wild Card, Division Series, League Champion -
ship Series or World Series games or for any additional Major
League championship season game played to break a tie.
4.04 Weather and Field Conditions
(a) The home team shall be the sole judge as to whether a game
shall not be started because of unsuitable weather conditions or
the unfit condition of the playing field, except for the second
game of a conventional or split doubleheader.
EXCEPTION: Any league may permanently authorize its
president to suspend the application of this rule as to that
league during the closing weeks of its championship sea-
son in order to assure that the championship is decided
each year on its merits. When the postponement of, and
possible failure to play, a game in the final series of a
championship season between any two teams might
affect the final standing of any club in the league, the
president, on appeal from any league club, may assume
the authority granted the home team by this rule.
(b) The umpire-in-chief of the first game shall be the sole judge as
to whether the second game of a conventional or split double-
header shall not be started because of unsuitable weather con-
ditions or the unfit condition of the playing field.
(c) A postponed game shall be a "No Game" and shall be treated in
the same manner as a game called before it has become a regu-
lation game within the meaning of Rule 7.01(e).
4.05 Special Ground Rules
The manager of the home team shall present to the umpire-in-chief
and the opposing manager any ground rules he thinks necessary
covering the overflow of spectators upon the playing field, batted
or thrown balls into such overflow, or any other contingencies. If
these rules are acceptable to the opposing manager they shall be

legal. If these rules are unacceptable to the opposing manager, the
umpire-in-chief shall make and enforce any special ground rules he
thinks are made necessary by ground conditions, which shall not
conflict with the official playing rules.
4.06 No Fraternization
Players in uniform shall not address or mingle with spectators, nor
sit in the stands before, during, or after a game. No manager, coach
or player shall address any spectator before or during a game.
Players of opposing teams shall not fraternize at any time while in
uniform.
4.07 Security
(a) No person shall be allowed on the playing field during a game
except players and coaches in uniform, managers, news pho-
tographers authorized by the home team, umpires, officers of
the law in uniform and watchmen or other employees of the
home club.
(b) The home team shall provide police protection sufficient to
preserve order. If a person, or persons, enter the playing field
during a game and interfere in any way with the play, the visit-
ing team may refuse to play until the field is cleared.
PENALTY: If the field is not cleared in a reasonable
length of time, which shall in no case be less than 15 min-
utes after the visiting team's refusal to play, the umpire-
in-chief may forfeit the game to the visiting team.
4.08 Doubleheaders
(a) (1) Only two championship games shall be played on one date.
Completion of a suspended game shall not violate this rule,
except for games in National Association Leagues.  See
Rule 7.02(b) Comment.
(a) (2) If two games are scheduled to be played for one admission
on one date, the first game shall be the regularly scheduled
game for that date.

(b) After the start of the first game of a conventional or split dou-
bleheader, that game shall be completed before the second
game of the doubleheader shall begin.
(c) The second game of a doubleheader shall start thirty minutes
after the first game is completed, unless a longer interval (not
to exceed forty-five minutes) is declared by the umpire-in-chief
and announced to the opposing managers at the end of the first
game.
EXCEPTION: If the League President has approved a
request of the home club for a longer interval between
games for some special event, the umpire-in-chief shall
declare such longer interval and announce it to the oppos-
ing managers. The umpire-in-chief of the first game shall
be the timekeeper controlling the interval between games.
(d) The umpire shall start the second game of a doubleheader, if at
all possible, and play shall continue as long as ground condi-
tions, local time restrictions, or weather permit.
(e) When a regularly scheduled doubleheader is delayed in starting
for any cause, any game that is started is the first game of the
doubleheader.
(f ) When a rescheduled game is part of a doubleheader the resched-
uled game shall be the second game, and the first game shall be
the regularly scheduled game for that date.
(g) (3.11) Between games of a doubleheader, or whenever a game
is suspended because of the unfitness of the playing field, the
umpire-in-chief shall have control of ground-keepers and assis-
tants for the purpose of making the playing field fit for play.
PENALTY: For violation, the umpire-in-chief may forfeit
the game to the visiting team.

Rule 5.03(c) to 5.04(b)
18
(c) Base coaches must remain within the coach's box consistent
with this Rule, except that a coach who has a play at his base
may leave the coach's box to signal the player to slide, advance
or return to a base if the coach does not interfere with the play
in any manner.  Other than exchanging equipment, all base
coaches shall refrain from physically touching base runners,
especially when signs are being given.
PENALTY: If a coach has positioned himself closer to home plate
than the coach's box or closer to fair territory than the coach's box
before a batted ball passes the coach, the umpire shall, upon com-
plaint by the opposing manager, strictly enforce the rule.  The
umpire shall warn the coach and instruct him to return to the box.
If the coach does not return to the box he shall be removed from the
game.  In addition, coaches who violate this Rule may be subject to
discipline by the League President.
5.04 Batting
(a) Batting Order
(1) Each player of the offensive team shall bat in the order
that his name appears in his team's batting order.
(2) The batting order shall be followed throughout the game
unless a player is substituted for another. In that case the
substitute shall take the place of the replaced player in the
batting order.
(3) The first batter in each inning after the first inning shall
be the player whose name follows that of the last player
who legally completed his time at bat in the preceding
inning.
(b) The Batter's Box
(1) The batter shall take his position in the batter's box
promptly when it is his time at bat.
(2) The batter shall not leave his position in the batter's box
after the pitcher comes to Set Position, or starts his
windup.

Rule 5.04(b)
19
PENALTY: If the pitcher pitches, the umpire shall call
"Ball" or "Strike," as the case may be.
Rule 5.04(b)(2) Comment: The batter leaves the batter's box at
the risk of having a strike delivered and called, unless he
requests the umpire to call "Time." The batter is not at liberty
to step in and out of the batter's box at will.
Once a batter has taken his position in the batter's box, he shall
not be permitted to step out of the batter's box in order to use
the rosin or the pine tar rag, unless there is a delay in the game
action or, in the judgment of the umpires, weather conditions
warrant an exception.
Umpires will not call "Time" at the request of the batter or any
member of his team once the pitcher has started his windup or
has come to a set position even though the batter claims "dust
in his eyes," "steamed glasses," "didn't get the sign" or for any
other cause.
Umpires may grant a hitter's request for "Time" once he is in
the batter's box, but the umpire should eliminate hitters walk-
ing out of the batter's box without reason. If umpires are not
lenient, batters will understand that they are in the batter's box
and they must remain there until the ball is pitched.  See Rule
5.04(b)(4).
If pitcher delays once the batter is in his box and the umpire
feels that the delay is not justified he may allow the batter to
step out of the box momentarily.
If after the pitcher starts his windup or comes to a "set posi-
tion" with a runner on, he does not go through with his pitch
because the batter has inadvertently caused the pitcher to inter-
rupt his delivery, it shall not be called a balk.  Both the pitcher
and batter have violated a rule and the umpire shall call time
and both the batter and pitcher start over from "scratch."
The following paragraph is additional material for Rule
5.04(b)(2) Comment, for National Association play:
If after the pitcher starts his windup or comes to a "set posi-
tion" with a runner on, he does not go through with his pitch
because the batter has stepped out of the box, the umpire shall
not call a balk.  Such action by the batter shall be treated as a

violation of the Batter's Box Rule and shall subject a batter to
the penalties set forth in Rule 5.04(b)(4)(A).
(3) If the batter refuses to take his position in the batter's box
during his time at bat, the umpire shall call a strike on the
batter. The ball is dead, and no runners may advance.
After the penalty, the batter may take his proper position
and the regular ball and strike count shall continue. If the
batter does not take his proper position before three
strikes have been called, the batter shall be declared out.
Rule 5.04(b)(3) Comment: The umpire shall give the batter a
reasonable opportunity to take his proper position in the bat-
ter's box after the umpire has called a strike pursuant to Rule
5.04(b)(3) and before the umpire calls a successive strike pur-
suant to Rule 5.04(b)(3).
(4) The Batter's Box Rule
(A) The batter shall keep at least one foot in the batter's
box throughout the batter's time at bat, unless one of
the following exceptions applies, in which case the
batter may leave the batter's box but not the dirt area
surrounding home plate:
(i) The batter swings at a pitch;
(ii) An attempted check swing is appealed to a
base umpire;
(iii) The batter is forced off balance or out of the
batter's box by a pitch;
(iv) A member of either team requests and is
granted "Time";
(v) A defensive player attempts a play on a run-
ner at any base;
(vi) The batter feints a bunt;
(vii) A wild pitch or passed ball occurs;
(viii) The pitcher leaves the dirt area of the pitching
mound after receiving the ball; or

Rule 5.04(b) to 5.05(a)
21
(ix) The catcher leaves the catcher's box to give
defensive signals.
If the batter intentionally leaves the batter's box and delays play,
and none of the exceptions listed in Rule 5.04(b)(4)(A)(i) through
(ix) applies, the umpire shall issue a warning to the batter for the
batter's first violation of this Rule in a game.  For a batter's second
or subsequent violations of this Rule in a game, the League
President may issue an appropriate discipline.  In National
Association play, for a batter's second or subsequent violations of
this Rule in a game, the umpire shall award a strike without the
pitcher having to deliver the pitch.  The ball is dead, and no runners
may advance.
(B) The batter may leave the batter's box and the dirt
area surrounding home plate when "Time" is called
for the purpose or as a result of
      (i) an injury or potential injury;
      (ii) making a substitution; or
     (iii) a conference by either team.
Rule 5.04(b)(4)(B) Comment: Umpires shall encourage the on-
deck batter to take a position in the batter's box quickly after the
previous batter reaches base or is put out.
(5) The batter's legal position shall be with both feet within
the batter's box.
APPROVED RULING: The lines defining the box are within
the batter's box.
(c) Completing Time at Bat
A batter has legally completed his time at bat when he is put out or
becomes a runner.
5.05 When the Batter Becomes a Runner
(a) The batter becomes a runner when:
(1) He hits a fair ball;

Rule 5.05(a)
22
Rule 5.05(a) Comment: If the batter hits a pitch that touches
the ground first, the ensuing action shall be the same as if he
hit the ball in flight.
(2) The third strike called by the umpire is not caught, pro-
viding (1) first base is unoccupied, or (2) first base is
occupied with two out;
Rule 5.05(a)(2) Comment:  A batter who does not realize his
situation on a third strike not caught, and who is not in the
process of running to first base, shall be declared out once he
leaves the dirt circle surrounding home plate.
(3) If the pitch touches the ground and bounces through the
strike zone it is a "ball."  If such a pitch touches the bat-
ter, he shall be awarded first base. If the batter swings at
such a pitch after two strikes, the ball cannot be caught,
for the purposes of Rule 5.05(b) and 5.09(a)(3).
(4) A fair ball, after having passed a fielder other than the
pitcher, or after having been touched by a fielder, includ-
ing the pitcher, shall touch an umpire or runner on fair
territory;
(5) A fair ball passes over a fence or into the stands at a dis-
tance from home base of 250 feet or more. Such hit enti-
tles the batter to a home run when he shall have touched
all bases legally. A fair fly ball that passes out of the play-
ing field at a point less than 250 feet from home base
shall entitle the batter to advance to second base only;
(6) A fair ball, after touching the ground, bounds into the
stands, or passes through, over or under a fence, or
through or under a scoreboard, or through or under
shrubbery, or vines on the fence, in which case the batter
and the runners shall be entitled to advance two bases;
(7) Any fair ball which, either before or after touching the
ground, passes through or under a fence, or through or
under a scoreboard, or through any opening in the fence
or scoreboard, or through or under shrubbery, or vines on

the fence, or which sticks in a fence or scoreboard, in
which case the batter and the runners shall be entitled to
two bases;
(8) Any bounding fair ball is deflected by the fielder into the
stands, or over or under a fence on fair or foul territory, in
which case the batter and all runners shall be entitled to
advance two bases;
(9) Any fair fly ball is deflected by the fielder into the stands,
or over the fence into foul territory, in which case the batter
shall be entitled to advance to second base; but if deflected
into the stands or over the fence in fair territory, the batter
shall be entitled to a home run.  However, should such a
fair fly be deflected at a point less than 250 feet from home
plate, the batter shall be entitled to two bases only.
(b) The batter becomes a runner and is entitled to first base with-
out liability to be put out (provided he advances to and touches
first base) when:
(1) Four "balls" have been called by the umpire;
Rule 5.05(b)(1) Comment: A batter who is entitled to first base
because of a base on balls, including an award of first base to a
batter by an umpire following a signal from a manager, must go
to first base and touch the base before other base runners are
forced to advance. This applies when bases are full and applies
when a substitute runner is put into the game.
If, in advancing, the base runner thinks there is a play and he
slides past the base before or after touching it he may be put
out by the fielder tagging him. If he fails to touch the base to
which he is entitled and attempts to advance beyond that base
he may be put out by tagging him or the base he missed.
(2) He is touched by a pitched ball which he is not attempt-
ing to hit unless (A) The ball is in the strike zone when it
touches the batter, or (B) The batter makes no attempt to
avoid being touched by the ball;
(2) If the ball is in the strike zone when it touches the batter,
it shall be called a strike, whether or not the batter tries to

avoid the ball. If the ball is outside the strike zone when
it touches the batter, it shall be called a ball if he makes
no attempt to avoid being touched.
APPROVED RULING: When the batter is touched by a
pitched ball which does not entitle him to first base, the
ball is dead and no runner may advance.
(3) The catcher or any fielder interferes with him. If a play
follows the interference, the manager of the offense may
advise the plate umpire that he elects to decline the inter-
ference penalty and accept the play. Such election shall
be made immediately at the end of the play.  However, if
the batter reaches first base on a hit, an error, a base on
balls, a hit batsman, or otherwise, and all other runners
advance at least one base, the play proceeds without ref-
erence to the interference.
Rule 5.05(b)(3) Comment: If catcher's interference is called
with a play in progress the umpire will allow the play to con-
tinue because the manager may elect to take the play. If the
batter-runner missed first base, or a runner misses his next
base, he shall be considered as having reached the base, as
stated in Note of Rule 5.06(e)(4).
Examples of plays the manager might elect to take:
1. Runner on third, one out, batter hits fly ball to the out-
field on which the runner scores but catcher's interfer-
ence was called.  The offensive manager may elect to
take the run and have batter called out or have runner
remain at third and batter awarded first base.
2. Runner on second base. Catcher interferes with batter as
he bunts ball fairly sending runner to third base.  The
manager may rather have runner on third base with an
out on the play than have runners on second and first.
If a runner is trying to score by a steal or squeeze from third
base, note the additional penalty set forth in Rule 6.01(g).
If the catcher interferes with the batter before the pitcher deliv-
ers the ball, it shall not be considered interference on the batter

under Rule 5.05(i)(3). In such cases, the umpire shall call
"Time" and the pitcher and batter start over from "scratch."
(4) A fair ball touches an umpire or a runner on fair territory
before touching a fielder.
(d) If a fair ball touches an umpire after having passed a
fielder other than the pitcher, or having touched a fielder,
including the pitcher, the ball is in play.
5.06 Running the Bases
(a) Occupying the Base
(1) A runner acquires the right to an unoccupied base when
he touches it before he is out. He is then entitled to it
until he is put out, or forced to vacate it for another run-
ner legally entitled to that base.
Rule 5.06(a)/5.06(c) Comment: If a runner legally acquires
title to a base, and the pitcher assumes his pitching position,
the runner may not return to a previously occupied base.
(2) Two runners may not occupy a base, but if, while the ball
is alive, two runners are touching a base, the following
runner shall be out when tagged and the preceding runner
is entitled to the base, unless Rule 5.06(b)(2) applies.
(b) Advancing Bases
(1) In advancing, a runner shall touch first, second, third and
home base in order.  If forced to return, he shall retouch
all bases in reverse order, unless the ball is dead under any
provision of Rule 5.06(c).  In such cases, the runner may
go directly to his original base.
(2) If a runner is forced to advance by reason of the batter
becoming a runner and two runners are touching a base to
which the following runner is forced, the following runner
is entitled to the base and the preceding runner shall be
out when tagged or when a fielder possesses the ball and
touches the base to which such preceding runner is forced.
(3) Each runner, other than the batter, may without liability
to be put out, advance one base when:

Rule 5.06(b)(3)
26
(A) There is a balk;
(B) The batter's advance without liability to be put
out forces the runner to vacate his base, or when
the batter hits a fair ball that touches another run-
ner or the umpire before such ball has been
touched by, or has passed a fielder, if the runner is
forced to advance;
Rule 5.06(b)(3)(B) Comment: A runner forced to advance
without liability to be put out may advance past the base to
which he is entitled only at his peril. If such a runner, forced to
advance, is put out for the third out before a preceding runner,
also forced to advance, touches home plate, the run shall score.
Play.  Two out, bases full, batter walks but runner from second
is overzealous and runs past third base toward home and is
tagged out on a throw by the catcher.  Even though two are out,
the run would score on the theory that the run was forced home
by the base on balls and that all the runners needed to do was
proceed and touch the next base.
(C) A fielder, after catching a fly ball, steps or falls
into any out-of-play area;
Rule 5.06(b)(3)(C) Comment: If a fielder, after having made a
legal catch, should step or fall into any out-of-play area, the
ball is dead and each runner shall advance one base, without
liability to be put out, from his last legally touched base at the
time the fielder entered such out-of-play area.
(D) While he is attempting to steal a base, the batter
is interfered with by the catcher or any other
fielder.
NOTE: When a runner is entitled to a base without liability
to be put out, while the ball is in play, or under any rule in
which the ball is in play after the runner reaches the base to
which he is entitled, and the runner fails to touch the base
to which he is entitled before attempting to advance to the
next base, the runner shall forfeit his exemption from lia-
bility to be put out, and he may be put out by tagging the

base or by tagging the runner before he returns to the
missed base;
(E) A fielder deliberately touches a pitched ball with
his cap, mask or any part of his uniform detached
from its proper place on his person. The ball is in
play, and the award is made from the position of
the runner at the time the ball was touched.
(4) Each runner including the batter-runner may, without liability
to be put out, advance:
(A) To home base, scoring a run, if a fair ball goes out
of the playing field in flight and he touched all
bases legally; or if a fair ball which, in the
umpire's judgment, would have gone out of the
playing field in flight, is deflected by the act of a
fielder in throwing his glove, cap, or any article of
his apparel;
(B) Three bases, if a fielder deliberately touches a fair
ball with his cap, mask or any part of his uniform
detached from its proper place on his person. The
ball is in play and the batter may advance to home
base at his peril;
(C) Three bases, if a fielder deliberately throws his
glove at and touches a fair ball. The ball is in play
and the batter may advance to home base at his
peril;
(D) Two bases, if a fielder deliberately touches a
thrown ball with his cap, mask or any part of his
uniform detached from its proper place on his
person. The ball is in play;
(E) Two bases, if a fielder deliberately throws his glove
at and touches a thrown ball. The ball is in play;
Rule 5.06(b)(4)(B) through (E) Comment: In applying (B-C-D-
E) the umpire must rule that the thrown glove or detached cap or
mask has touched the ball. There is no penalty if the ball is not
touched.

Rule 5.06(b)(4)
28
Under (C-E) this penalty shall not be invoked against a fielder
whose glove is carried off his hand by the force of a batted or
thrown ball, or when his glove flies off his hand as he makes an
obvious effort to make a legitimate catch.
(F) Two bases, if a fair ball bounces or is deflected
into the stands outside the first or third base foul
lines; or if it goes through or under a field fence, or
through or under a scoreboard, or through or under
shrubbery or vines on the fence; or if it sticks in
such fence, scoreboard, shrubbery or vines;
(G) Two bases when, with no spectators on the play-
ing field, a thrown ball goes into the stands, or
into a bench (whether or not the ball rebounds
into the field), or over or under or through a field
fence, or on a slanting part of the screen above the
backstop, or remains in the meshes of a wire
screen protecting spectators. The ball is dead.
When such wild throw is the first play by an
infielder, the umpire, in awarding such bases,
shall be governed by the position of the runners at
the time the ball was pitched; in all other cases the
umpire shall be governed by the position of the
runners at the time the wild throw was made;
APPROVED RULING: If all runners, including the bat-
ter-runner, have advanced at least one base when an
infielder makes a wild throw on the first play after the
pitch, the award shall be governed by the position of the
runners when the wild throw was made.
Rule 5.06(b)(4)(G) Comment: In certain circumstances it is
impossible to award a runner two bases. Example: Runner on
first. Batter hits fly to short right. Runner holds up between
first and second and batter comes around first and pulls up
behind him. Ball falls safely. Outfielder, in throwing to first,
throws ball into stands.
APPROVED RULING: Since no runner, when the ball is
dead, may advance beyond the base to which he is enti-
tled, the runner originally on first base goes to third base
and the batter is held at second base.

Rule 5.06(b)(4)
29
The term "when the wild throw was made" means when
the throw actually left the player's hand and not when the
thrown ball hit the ground, passes a receiving fielder or
goes out of play into the stands.
The position of the batter-runner at the time the wild
throw left the thrower's hand is the key in deciding the
award of bases. If the batter-runner has not reached first
base, the award is two bases at the time the pitch was
made for all runners. The decision as to whether the bat-
ter-runner has reached first base before the throw is a
judgment call.
If an unusual play arises where a first throw by an
infielder goes into stands or dugout but the batter did not
become a runner (such as catcher throwing ball into
stands in attempt to get runner from third trying to score
on passed ball or wild pitch) award of two bases shall be
from the position of the runners at the time of the throw.
(For the purpose of Rule 5.06(b)(4)(G) a catcher is con-
sidered an infielder.)
PLAYRunner on first base, batter hits a ball to the
shortstop, who throws to second base too late to get run-
ner at second, and second baseman throws toward first
base after batter has crossed first base.
RULING: Runner at second scores. (On this play, only if
batter-runner is past first base when throw is made is he
awarded third base.)
(H) One base, if a ball, pitched to the batter, or thrown
by the pitcher from his position on the pitcher's
plate to a base to catch a runner, goes into a stand
or a bench, or over or through a field fence or
backstop. The ball is dead;
APPROVED RULING: When a wild pitch or passed ball
goes through or by the catcher, or deflects off the catcher,
and goes directly into the dugout, stands, above the
break, or any area where the ball is dead, the awarding of
bases shall be one base. One base shall also be awarded if

the pitcher while in contact with the rubber, throws to a
base, and the throw goes directly into the stands or into
any area where the ball is dead.
If, however, the pitched or thrown ball goes through or by
the catcher or through the fielder, and remains on the
playing field, and is subsequently kicked or deflected
into the dugout, stands or other area where the ball is
dead, the awarding of bases shall be two bases from posi-
tion of runners at the time of the pitch or throw.
( I) One base, if the batter becomes a runner on Ball
Four or Strike Three, when the pitch passes the
catcher and lodges in the umpire's mask or para-
phernalia.
( I) If the batter becomes a runner on a wild pitch
which entitles the runners to advance one base,
the batter-runner shall be entitled to first base
only.
Rule 5.06(b)(4)(I) Comment: The fact a runner is awarded a
base or bases without liability to be put out does not relieve
him of the responsibility to touch the base he is awarded and
all intervening bases. For example:  Batter hits a ground ball
which an infielder throws into the stands but the batter-runner
missed first base. He may be called out on appeal for missing
first base after the ball is put in play even though he was
"awarded" second base.
If a runner is forced to return to a base after a catch, he must
retouch his original base even though, because of some ground
rule or other rule, he is awarded additional bases. He may
retouch while the ball is dead and the award is then made from
his original base.
(c) Dead Balls
The ball becomes dead and runners advance one base, or return to
their bases, without liability to be put out, when:

(1) A pitched ball touches a batter, or his clothing, while
in his legal batting position; runners, if forced,
advance;
(2) The plate umpire interferes with the catcher's throw
attempting to prevent a stolen base or retire a runner
on a pick-off play; runners may not advance.
NOTE: The interference shall be disregarded if the
catcher's throw retires the runner.
While the ball is dead no player may be put out, no bases may be
run and no runs may be scored, except that runners may advance
one or more bases as the result of acts which occurred while the
ball was alive (such as, but not limited to a balk, an overthrow,
interference, or a home run or other fair ball hit out of the playing
field).
Rule 5.06(c)(2) Comment:  Umpire interference may also
occur when an umpire interferes with a catcher returning the
ball to the pitcher.
(3) A balk is committed; runners advance; (See Penalty
6.02(a)  (Penalty 8.05).)
(4) A ball is illegally batted; runners return;
(5) A foul ball is not caught, in which case runners return
to their bases. The umpire-in-chief shall not put the
ball in play until all runners have retouched their
bases;
(6) A fair ball touches a runner or an umpire on fair terri-
tory before it touches an infielder including the
pitcher, or touches an umpire before it has passed an
infielder other than the pitcher; runners advance, if
forced.
(6) If a fair ball goes through, or by, an infielder, no other
infielder has a chance to make a play on the ball and
the ball touches a runner immediately behind the
infielder that the ball went through, or by, the ball is in

play and the umpire shall not declare the runner out. If
a fair ball touches a runner after being deflected by an
infielder, the ball is in play and the umpire shall not
declare the runner out;
Rule 5.06(c)(6) Comment: If a fair ball touches an umpire
working in the infield after it has bounded past, or over, the
pitcher, it is a dead ball. If a batted ball is deflected by a fielder
in fair territory and hits a runner or an umpire while still in
flight and then caught by an infielder it shall not be a catch, but
the ball shall remain in play.
(7) A pitched ball lodges in the umpire's or catcher's
mask or paraphernalia, and remains out of play,
runners advance one base;
Rule 5.06(c)(7) Comment: If a foul tip hits the umpire and is
caught by a fielder on the rebound, the ball is "dead" and the
batsman cannot be called out.  The same shall apply where
such foul tip lodges in the umpire's mask or other parapherna-
lia.
If a third strike (not a foul tip) passes the catcher and hits an
umpire, the ball is in play. If such ball rebounds and is caught
by a fielder before it touches the ground, the batsman is not
out on such a catch, but the ball remains in play and the bats-
man may be retired at first base, or touched with the ball for
the out.
If a pitched ball lodges in the umpire's or catcher's mask or
paraphernalia, and remains out of play, on the third strike or
fourth ball, then the batter is entitled to first base and all run-
ners advance one base. If the count on the batter is less than
three balls, runners advance one base.
(8) Any legal pitch touches a runner trying to score; runners
advance.

Rule 5.07

5.07 Pitching
(a) Legal Pitching Delivery
There are two legal pitching positions, the Windup Position and the
Set Position, and either position may be used at any time.
Pitchers shall take signs from the catcher while in contact with the
pitcher's plate.
Rule 5.07(a) Comment: Pitchers may disengage the rubber
after taking their signs but may not step quickly onto the rub-
ber and pitch. This may be judged a quick pitch by the umpire.
When the pitcher disengages the rubber, he must drop his
hands to his sides.
Pitchers will not be allowed to disengage the rubber after tak-
ing each sign.
The pitcher may not take a second step toward home plate with
either foot or otherwise reset his pivot foot in his delivery of
the pitch.  If there is a runner, or runners, on base it is a balk
under Rule 6.02(a); if the bases are unoccupied it is an illegal
pitch under Rule 6.02(b).
(1) The Windup Position
The pitcher shall stand facing the batter, his pivot foot in con-
tact with the pitcher's plate and the other foot free. From this
position any natural movement associated with his delivery of
the ball to the batter commits him to the pitch without interrup-
tion or alteration. He shall not raise either foot from the
ground, except that in his actual delivery of the ball to the bat-
ter, he may take one step backward, and one step forward with
his free foot.
When a pitcher holds the ball with both hands in front of his
body, with his pivot foot in contact with the pitcher's plate and
his other foot free, he will be considered in the Windup
Position.
Rule 5.07(a)(1) Comment: In the Windup Position, a pitcher is
permitted to have his "free" foot on the rubber, in front of the
rubber, behind the rubber or off the side of the rubber.

Rule 5.07(a)
34
From the Windup Position, the pitcher may:
(A) deliver the ball to the batter, or
(B) step and throw to a base in an attempt to pick-off a
runner, or
(C) disengage the rubber (if he does he must drop his hand
to his sides).
In disengaging the rubber the pitcher must step off with his
pivot foot and not his free foot first. He may not go into a set or
stretch positionif he does it is a balk.
(2) The Set Position
Set Position shall be indicated by the pitcher when he stands
facing the batter with his pivot foot in contact with, and his
other foot in front of, the pitcher's plate, holding the ball in
both hands in front of his body and coming to a complete stop.
From such Set Position he may deliver the ball to the batter,
throw to a base or step backward off the pitcher's plate with his
pivot foot. Before assuming Set Position, the pitcher may elect
to make any natural preliminary motion such as that known as
"the stretch." But if he so elects, he shall come to Set Position
before delivering the ball to the batter. After assuming Set
Position, any natural motion associated with his delivery of the
ball to the batter commits him to the pitch without alteration or
interruption.
Preparatory to coming to a set position, the pitcher shall have
one hand on his side; from this position he shall go to his set
position as defined in Rule 5.07(a)(2) without interruption and
in one continuous motion.
The pitcher, following his stretch, must (a) hold the ball in both
hands in front of his body and (b) come to a complete stop.
This must be enforced. Umpires should watch this closely.
Pitchers are constantly attempting to "beat the rule" in their
efforts to hold runners on bases and in cases where the pitcher
fails to make a complete "stop" called for in the rules, the
umpire should immediately call a "Balk."

Rule 5.07(a) to 5.07(c)
35
Rule 5.07(a)(2) Comment: With no runners on base, the
pitcher is not required to come to a complete stop when using
the Set Position.  If, however, in the umpire's judgment, a
pitcher delivers the ball in a deliberate effort to catch the batter
off guard, this delivery shall be deemed a quick pitch, for
which the penalty is a ball.  See Rule 6.02(a)(5) Comment.
With a runner or runners on base, a pitcher will be presumed to
be pitching from the Set Position if he stands with his pivot
foot in contact with and parallel to the pitcher's plate, and his
other foot in front of the pitcher's plate, unless he notifies the
umpire that he will be pitching from the Windup Position
under such circumstances prior to the beginning of an at-bat.
A pitcher will be permitted to notify the umpire that he is
pitching from the Windup Position within an at-bat only in the
event of (i) a substitution by the offensive team; or (ii) immedi-
ately upon the advancement of one or more runners (i.e., after
one or more base runners advance but before the delivery of
the next pitch).
(b) Warm-Up Pitches
When a pitcher takes his position at the beginning of each inning,
or when he relieves another pitcher, he shall be permitted to pitch
preparatory pitches to his catcher during which play shall be sus-
pended.  A league by its own action may limit the number of
preparatory pitches and/or may limit the amount of time such
preparatory pitches may consume.  If a sudden emergency causes a
pitcher to be summoned into the game without any opportunity to
warm up, the umpire-in-chief shall allow him as many pitches as
the umpire deems necessary.
(c) Pitcher Delays
When the bases are unoccupied, the pitcher shall deliver the ball to
the batter within 12 seconds after he receives the ball. Each time
the pitcher delays the game by violating this rule, the umpire shall
call "Ball."
The 12-second timing starts when the pitcher is in possession of the
ball and the batter is in the box, alert to the pitcher. The timing
stops when the pitcher releases the ball.

Rule 5.07(c) to 5.07(f)
36
The intent of this rule is to avoid unnecessary delays. The umpire
shall insist that the catcher return the ball promptly to the pitcher, and
that the pitcher take his position on the rubber promptly. Obvious
delay by the pitcher should instantly be penalized by the umpire.
(d) Throwing to the Bases
At any time during the pitcher's preliminary movements and until
his natural pitching motion commits him to the pitch, he may throw
to any base provided he steps directly toward such base before
making the throw.
Rule 5.07(d) Comment: The pitcher shall step "ahead of the
throw." A snap throw followed by the step directly toward the
base is a balk.
(e) Effect of Removing Pivot Foot From Plate
If the pitcher removes his pivot foot from contact with the pitcher's
plate by stepping backward with that foot, he thereby becomes an
infielder and if he makes a wild throw from that position, it shall be
considered the same as a wild throw by any other infielder.
Rule 5.07(e) Comment: The pitcher, while off the rubber, may
throw to any base. If he makes a wild throw, such throw is the
throw of an infielder and what follows is governed by the rules
covering a ball thrown by a fielder.
(f ) Ambidextrous Pitchers
A pitcher must indicate visually to the umpire-in-chief, the batter and
any runners the hand with which he intends to pitch, which may be
done by wearing his glove on the other hand while touching the
pitcher's plate. The pitcher is not permitted to pitch with the other
hand until the batter is retired, the batter becomes a runner, the inning
ends, the batter is substituted for by a pinch-hitter or the pitcher
incurs an injury. In the event a pitcher switches pitching hands during
an at-bat because he has suffered an injury, the pitcher may not, for
the remainder of the game, pitch with the hand from which he has
switched. The pitcher shall not be given the opportunity to throw any
preparatory pitches after switching pitching hands. Any change of
pitching hands must be indicated clearly to the umpire-in-chief.

Rule 5.08(a) to 5.08(b)
37
5.08 How a Team Scores
(a) One run shall be scored each time a runner legally advances to
and touches first, second, third and home base before three men
are put out to end the inning.
EXCEPTION: A run is not scored if the runner
advances to home base during a play in which the third
out is made (1) by the batter-runner before he touches
first base; (2) by any runner being forced out; or (3) by
a preceding runner who is declared out because he
failed to touch one of the bases.
Rule 5.08(a) Comment: A run legally scored cannot be nulli-
fied by subsequent action of the runner, such as but not limited
to an effort to return to third base in the belief that he had left
the base before a caught fly ball.
(b) When the winning run is scored in the last half-inning of a reg-
ulation game, or in the last half of an extra inning, as the result
of a base on balls, hit batter or any other play with the bases
full which forces the batter and all other runners to advance
without liability of being put out, the umpire shall not declare
the game ended until the runner forced to advance from third
has touched home base and the batter-runner has touched first
base.
Rule 5.08(b) Comment: An exception will be if fans rush onto
the field and physically prevent the runner from touching home
plate or the batter from touching first base. In such cases, the
umpires shall award the runner the base because of the obstruc-
tion by the fans.
PENALTY: If the runner on third refuses to advance to
and touch home base in a reasonable time, the umpire
shall disallow the run, call out the offending player and
order the game resumed. If, with two out, the batter-run-
ner refuses to advance to and touch first base, the
umpire shall disallow the run, call out the offending
player, and order the game resumed. If, before two are
out, the batter-runner refuses to advance to and touch

first base, the run shall count, but the offending player
shall be called out.
Rule 5.08 Comment: 
APPROVED RULING: No run shall score during a play
in which the third out is made by the batter-runner before
he touches first base. Example: One out, Jones on sec-
ond, Smith on first. The batter, Brown, hits safely. Jones
scores. Smith is out on the throw to the plate. Two outs.
But Brown missed first base. The ball is thrown to first,
an appeal is made, and Brown is out. Three outs. Since
Jones crossed the plate during a play in which the third
out was made by the batter-runner before he touched first
base, Jones' run does not count.
APPROVED RULING: Following runners are not affected
by an act of a preceding runner unless two are out.
EXAMPLE: One out, Jones on second, Smith on first,
and batter, Brown, hits home run inside the park. Jones
fails to touch third on his way to the plate. Smith and
Brown score. The defense holds the ball on third, appeals
to umpire, and Jones is out. Smith's and Brown's runs
count.
APPROVED RULING: Two out, Jones on second, Smith
on first and batter, Brown, hits home run inside the park.
All three runs cross the plate. But Jones missed third
base, and on appeal is declared out. Three outs. Smith's
and Brown's runs are voided. No score on the play.
APPROVED RULING: One out, Jones on third, Smith on
second. Batter Brown flies out to center. Two out. Jones
scores after catch and Smith scores on bad throw to plate.
But Jones, on appeal, is adjudged to have left third before
the catch and is out. Three outs. No runs.
APPROVED RULING: Two out, bases full, batter hits
home run over fence. Batter, on appeal, is declared out
for missing first base. Three outs. No run counts.

Rule 5.08(b) to 5.09(a)(1)
39
When a runner misses a base and a fielder holds the ball
on a missed base, or on the base originally occupied by
the runner if a fly ball is caught, and appeals for the
umpire's decision, the runner is out when the umpire sus-
tains the appeal; all runners may score if possible, except
that with two out the runner is out at the moment he
misses the bag, if an appeal is sustained as applied to the
following runners.
APPROVED RULING: One out, Jones on third, Smith on
first, and Brown flies out to right field. Two outs. Jones
tags up and scores after the catch. Smith attempted to
return to first but the right fielder's throw beat him to the
base. Three outs. But Jones scored before the throw to
catch Smith reached first base, hence Jones' run counts.
It was not a force play.
5.09 Making an Out
(a) Retiring the Batter
A batter is out when:
(1) His fair or foul fly ball (other than a foul tip) is legally
caught by a fielder;
Rule 5.09(a)(1) Comment: A fielder may reach into, but not
step into, a dugout to make a catch, and if he holds the ball, the
catch shall be allowed.  A fielder, in order to make a catch on a
foul ball nearing a dugout or other out-of-play area (such as the
stands), must have one or both feet on or over the playing sur-
face (including the lip of the dugout) and neither foot on the
ground inside the dugout or in any other out-of-play area.  Ball
is in play, unless the fielder, after making a legal catch, steps or
falls into a dugout or other out-of-play area, in which case the
ball is dead.  Status of runners shall be as described in Rule
5.06(b)(3)(C) Comment.
A catch is the act of a fielder in getting secure possession in his
hand or glove of a ball in flight and firmly holding it; providing he
does not use his cap, protector, pocket or any other part of his uni-
form in getting possession. It is not a catch, however, if simultane-
ously or immediately following his contact with the ball, he collides

with a player, or with a wall, or if he falls down, and as a result of
such collision or falling, drops the ball. It is not a catch if a fielder
touches a fly ball which then hits a member of the offensive team or
an umpire and then is caught by another defensive player. In estab-
lishing the validity of the catch, the fielder shall hold the ball long
enough to prove that he has complete control of the ball and that his
release of the ball is voluntary and intentional. If the fielder has
made the catch and drops the ball while in the act of making a throw
following the catch, the ball shall be adjudged to have been caught.
Catch Comment: A catch is legal if the ball is finally held by
any fielder, even though juggled, or held by another fielder
before it touches the ground. Runners may leave their bases the
instant the first fielder touches the ball. A fielder may reach
over a fence, railing, rope or other line of demarcation to make
a catch. He may jump on top of a railing, or canvas that may be
in foul ground. No interference should be allowed when a
fielder reaches over a fence, railing, rope or into a stand to
catch a ball. He does so at his own risk.
If a fielder, attempting a catch at the edge of the dugout, is
"held up" and kept from an apparent fall by a player or players
of either team and the catch is made, it shall be allowed.
(2) A third strike is legally caught by the catcher;
Rule 5.09 (a )(2) Comment: "Legally caught" means in the
catcher's glove before the ball touches the ground. It is not
legal if the ball lodges in his clothing or paraphernalia; or if it
touches the umpire and is caught by the catcher on the
rebound.
If a foul tip first strikes the catcher's glove and then goes on
through and is caught by both hands against his body or protec-
tor, before the ball touches the ground, it is a strike, and if third
strike, batter is out. If smothered against his body or protector,
it is a catch provided the ball struck the catcher's glove or hand
first.
(3) A third strike is not caught by the catcher when first base
is occupied before two are out;
(4) He bunts foul on third strike;

Rule 5.09(a)(5) to 5.09(a)(8)
41
(5) An Infield Fly is declared;
(6) He attempts to hit a third strike and the ball touches him;
(7) His fair ball touches him before touching a fielder. If the
batter is in a legal position in the batter's box, see Rule
5.04(b)(5), and, in the umpire's judgment, there was no
intention to interfere with the course of the ball, a batted
ball that strikes the batter or his bat shall be ruled a foul
ball;
(8) After hitting or bunting a fair ball, his bat hits the ball a
second time in fair territory. The ball is dead and no run-
ners may advance. If the batter-runner drops his bat and
the ball rolls against the bat in fair territory and, in the
umpire's judgment, there was no intention to interfere
with the course of the ball, the ball is alive and in play. If
the batter is in a legal position in the batter's box, see
Rule 5.04(b)(5), and, in the umpire's judgment, there was
no intention to interfere with the course of the ball, a bat-
ted ball that strikes the batter or his bat shall be ruled a
foul ball;
Rule 5.09(a)(8) Comment: If a bat breaks and part of it is in
fair territory and is hit by a batted ball or part of it hits a runner
or fielder, play shall continue and no interference called.  If a
batted ball hits part of a broken bat in foul territory, it is a foul
ball.
If a whole bat is thrown into fair or foul territory and interferes
with a defensive player attempting to make a play, interference
shall be called, whether intentional or not.
In cases where the batting helmet is accidentally hit with a bat-
ted ball on or over fair territory or a thrown ball, the ball
remains in play the same as if it has not hit the helmet.
If a batted ball strikes a batting helmet or any other object for-
eign to the natural ground while on foul territory, it is a foul
ball and the ball is dead.
If, in the umpire's judgment, there is intent on the part of a
baserunner to interfere with a batted or thrown ball by drop-
ping the helmet or throwing it at the ball, then the runner would

be out, the ball dead and runners would return to last base
legally touched.
(9) After hitting or bunting a ball that continues to move over
foul territory, he intentionally deflects the course of the
ball in any manner while running to first base. The ball is
dead and no runners may advance;
(10) After a third strike or after he hits a fair ball, he or first
base is tagged before he touches first base;
(11) In running the last half of the distance from home base to
first base, while the ball is being fielded to first base, he
runs outside (to the right of ) the three-foot line, or inside
(to the left of ) the foul line, and in the umpire's judgment
in so doing interferes with the fielder taking the throw at
first base, in which case the ball is dead; except that he
may run outside (to the right of ) the three-foot line or
inside (to the left of ) the foul line to avoid a fielder
attempting to field a batted ball;
Rule 5.09(a)(11) Comment: The lines marking the three-foot
lane are a part of that lane and a batter-runner is required to
have both feet within the three-foot lane or on the lines mark-
ing the lane.  The batter-runner is permitted to exit the three-
foot lane by means of a step, stride, reach or slide in the imme-
diate vicinity of first base for the sole purpose of touching first
base.
(12) An infielder intentionally drops a fair fly ball or line
drive, with first, first and second, first and third, or first,
second and third base occupied before two are out. The
ball is dead and runner or runners shall return to their
original base or bases;
APPROVED RULING:  In this situation, the batter is
not out if the infielder permits the ball to drop
untouched to the ground, except when the Infield Fly
rule applies.
(13) A preceding runner shall, in the umpire's judgment,
intentionally interfere with a fielder who is attempting to

catch a thrown ball or to throw a ball in an attempt to
complete any play;
Rule 5.09(a )(13) Comment: The objective of this rule is to
penalize the offensive team for deliberate, unwarranted,
unsportsmanlike action by the runner in leaving the baseline
for the obvious purpose of crashing the pivot man on a double
play, rather than trying to reach the base. Obviously this is an
umpire's judgment play.  (See Rule 6.01(j).)
(14) With two out, a runner on third base, and two strikes on
the batter, the runner attempts to steal home base on a
legal pitch and the ball touches the runner in the batter's
strike zone. The umpire shall call "Strike Three," the bat-
ter is out and the run shall not count; before two are out,
the umpire shall call "Strike Three," the ball is dead, and
the run counts;
(15) A member of his team (other than a runner) hinders a
fielder's attempt to catch or field a batted ball. See Rule
6.01(b). For interference by a runner, see Rule 5.09(b)(3).
(b) Retiring a Runner
Any runner is out when:
(1) He runs more than three feet away from his base path to
avoid being tagged unless his action is to avoid interfer-
ence with a fielder fielding a batted ball. A runner's base
path is established when the tag attempt occurs and is a
straight line from the runner to the base he is attempting
to reach safely; or
(2) after touching first base, he leaves the base path, obvi-
ously abandoning his effort to touch the next base;
Rule 5.09(b)(1) and (2) Comment:  Any runner after reaching
first base who leaves the base path heading for his dugout or
his position believing that there is no further play, may be
declared out if the umpire judges the act of the runner to be
considered abandoning his efforts to run the bases. Even

though an out is called, the ball remains in play in regard to any
other runner.
This rule also covers the following and similar plays: Less than
two out, score tied last of ninth inning, runner on first, batter
hits a ball out of park for winning run, the runner on first passes
second and thinking the home run automatically wins the
game, cuts across diamond toward his bench as batter-runner
circles bases. In this case, the base runner would be called out
"for abandoning his effort to touch the next base" and batter-
runner permitted to continue around bases to make his home
run valid. If there are two out, home run would not count.  See
Rule 5.09(d).  This is not an appeal play.
PLAYRunner believing he is called out on a tag at first
or third base starts for the dugout and progresses a rea-
sonable distance still indicating by his actions that he is
out, shall be declared out for abandoning the bases.
(3) He intentionally interferes with a thrown ball; or hinders a
fielder attempting to make a play on a batted ball (see
Rule 6.01(j));
PENALTY: For penalties applying to a runner's inten-
tional interference with a thrown ball or his hindrance
of a fielder's attempt to make a play on a batted ball, see
Rule 6.01(a) PENALTY FOR INTERFERENCE Com -
ment.
(4) He is tagged, when the ball is alive, while off his base.
EXCEPTION: A batter-runner cannot be tagged out after
overrunning or oversliding first base if he returns imme-
diately to the base;
APPROVED RULING: (A) If the impact of a runner
breaks a base loose from its position, no play can be
made on that runner at that base if he had reached the
base safely.
APPROVED RULING: (B) If a base is dislodged from its
position during a play, any following runner on the same
play shall be considered as touching or occupying the

base if, in the umpire's judgment, he touches or occupies
the point marked by the dislodged bag.
(5) He fails to retouch his base after a fair or foul ball is
legally caught before he, or his base, is tagged by a
fielder. He shall not be called out for failure to retouch his
base after the first following pitch, or any play or
attempted play. This is an appeal play;
Rule 5.09(b)(5) Comment: Runners need not "tag up" on a
foul tip. They may steal on a foul tip. If a so-called tip is not
caught, it becomes an ordinary foul. Runners then return to
their bases.
(6) He or the next base is tagged before he touches the next
base, after he has been forced to advance by reason of the
batter becoming a runner. However, if a following runner
is put out on a force play, the force is removed and the
runner must be tagged to be put out. The force is removed
as soon as the runner touches the base to which he is
forced to advance, and if he overslides or overruns the
base, the runner must be tagged to be put out. However, if
the forced runner, after touching the next base, retreats
for any reason towards the base he had last occupied, the
force play is reinstated, and he can again be put out if the
defense tags the base to which he is forced;
Rule 5.09(b)(6) Comment:
PLAYRunner on first and three balls on batter:  Runner
steals on the next pitch, which is fourth ball, but after
having touched second he overslides or overruns that
base.  Catcher's throw catches him before he can return.
Ruling is that runner is out.  (Force out is removed.)
Oversliding and overrunning situations arise at bases
other than first base.  For instance, before two are out,
and runners on first and second, or first, second and third,
the ball is hit to an infielder who tries for the double play.
The runner on first beats the throw to second base but
overslides the base. The relay is made to first base and the
batter-runner is out. The first baseman, seeing the runner

at second base off the bag, makes the return throw to sec-
ond and the runner is tagged off the base. Meanwhile run-
ners have crossed the plate.  The question is: Is this a
force play?  Was the force removed when the batter-run-
ner was out at first base?  Do the runs that crossed the
plate during this play and before the third out was made
when the runner was tagged at second, count?  Answer:
The runs score.  It is not a force play.  It is a tag play.
(7) He is touched by a fair ball in fair territory before the ball
has touched or passed an infielder. The ball is dead and
no runner may score, nor runners advance, except runners
forced to advance. EXCEPTION: If a runner is touching
his base when touched by an Infield Fly, he is not out,
although the batter is out;
Rule 5.09(b)(7) Comment: If two runners are touched by the
same fair ball, only the first one is out because the ball is
instantly dead.
If a runner is touched by an Infield Fly when he is not
touching his base, both the runner and batter are out.
(8) He attempts to score on a play in which the batter interferes
with the play at home base before two are out. With two
out, the interference puts the batter out and no score counts;
(9) He passes a preceding runner before such runner is out;
Rule 5.09(b)(9) Comment: A runner may be deemed to have
passed a preceding (i.e., lead) runner based on his actions or
the actions of a preceding runner. 
PLAYRunners on second base and third base with one out.
The runner from third base (i.e., the lead runner) makes an
advance toward home and is caught in a rundown between
third base and home plate.  Believing the lead runner will be
tagged out, the runner at second base (i.e., the trailing runner)
advances to third base.  Before being tagged, the lead runner
runs back to and beyond third base toward left field.  At this
time, the trailing runner has passed the lead runner as a result
of the lead runner's actions.  As a result, the trailing runner is

out and third base is unoccupied.  The lead runner is entitled
to third base if he returns to touch it before he is out, see Rule
5.06(a)(1), unless he is declared out for abandoning the
bases.
(10) After he has acquired legal possession of a base, he runs
the bases in reverse order for the purpose of confusing the
defense or making a travesty of the game. The umpire
shall immediately call "Time" and declare the runner out;
Rule 5.09(b)(10) Comment: If a runner touches an unoccupied
base and then thinks the ball was caught or is decoyed into
returning to the base he last touched, he may be put out run-
ning back to that base, but if he reaches the previously occu-
pied base safely he cannot be put out while in contact with that
base.
(11) He fails to return at once to first base after overrunning or
oversliding that base. If he attempts to run to second he is
out when tagged. If, after overrunning or oversliding first
base he starts toward the dugout, or toward his position,
and fails to return to first base at once, he is out, on
appeal, when he or the base is tagged;
Rule 5.09(b)(11) Comment: Runner who touches first base in
overrunning and is declared safe by the umpire has, within the
intent of Rule 5.08(a) "reached first base" and any run which
scores on such a play counts, even though the runner subse-
quently becomes the third out for failure to return "at once," as
covered in Rule 5.09(b)(11).
(12) In running or sliding for home base, he fails to touch
home base and makes no attempt to return to the base,
when a fielder holds the ball in his hand, while touching
home base, and appeals to the umpire for the decision;
Rule 5.09(b)(12) Comment: This rule applies only where run-
ner is on his way to the bench and the catcher would be
required to chase him. It does not apply to the ordinary play
where the runner misses the plate and then immediately makes
an effort to touch the plate before being tagged. In that case,
runner must be tagged.

(13) A play on him is being made and a member of his team
(other than a runner) hinders a fielder's attempt to field a
thrown ball.  See Rule 5.09(b)(3).  For interference by a
runner, see Rule 5.09(b)(3).
(c) Appeal Plays
Any runner shall be called out, on appeal, when:
(1) After a fly ball is caught, he fails to retouch his original
base before he or his original base is tagged;
Rule 5.09(c)(1) Comment: "Retouch," in this rule, means to
tag up and start from a contact with the base after the ball is
caught. A runner is not permitted to take a flying start from a
position in back of his base.  Such runner shall be called out on
appeal.
(2) With the ball in play, while advancing or returning to a
base, he fails to touch each base in order before he, or a
missed base, is tagged;
APPROVED RULING: (A) No runner may return to
touch a missed base after a following runner has scored.
(B) When the ball is dead, no runner may return to touch
a missed base or one he has left after he has advanced to
and touched a base beyond the missed base.
Rule 5.09(c)(2) Comment:
PLAY (A) Batter hits ball out of park or ground rule
double and misses first base (ball is dead)he may
return to first base to correct his mistake before he
touches second but if he touches second he may not
return to first and if defensive team appeals he is declared
out at first.
PLAY (B) Batter hits ball to shortstop who throws wild
into stand (ball is dead)batter-runner misses first base
but is awarded second base on the overthrow. Even
though the umpire has awarded the runner second base
on the overthrow, the runner must touch first base before
he proceeds to second base.
These are appeal plays.

(3) He overruns or overslides first base and fails to return to
the base immediately, and he or the base is tagged prior
to the runner returning to first base;
(4) He fails to touch home base and makes no attempt to
return to that base, and home base is tagged.
Any appeal under this rule must be made before the next pitch, or
any play or attempted play. If the violation occurs during a play
which ends a half-inning, the appeal must be made before the
defensive team leaves the field.
An appeal is not to be interpreted as a play or an attempted play.
Successive appeals may not be made on a runner at the same base.
If the defensive team on its first appeal errs, a request for a second
appeal on the same runner at the same base shall not be allowed by
the umpire. (Intended meaning of the word "err" is that the defen-
sive team in making an appeal threw the ball out of play. For exam-
ple, if the pitcher threw to first base to appeal and threw the ball
into the stands, no second appeal would be allowed.)
Appeal plays may require an umpire to recognize an apparent
"fourth out." If the third out is made during a play in which an
appeal play is sustained on another runner, the appeal play decision
takes precedence in determining the out. If there is more than one
appeal during a play that ends a half-inning, the defense may elect
to take the out that gives it the advantage. For the purpose of this
rule, the defensive team has "left the field" when the pitcher and all
infielders have left fair territory on their way to the bench or club-
house.
Rule 5.09(c) Comment: If two runners arrive at home base
about the same time and the first runner misses home plate but
a second runner legally touches the plate, the runner is tagged
out on his attempt to come back and touch the base or is called
out, on appeal, then he shall be considered as having been put
out before the second runner scored and being the third out.
Second runner's run shall not count, as provided in Rule
5.09(d).
If a pitcher balks when making an appeal, such act shall be a
play.  An appeal should be clearly intended as an appeal, either

by a verbal request by the player or an act that unmistakably
indicates an appeal to the umpire.  A player, inadvertently step-
ping on the base with a ball in his hand, would not constitute
an appeal.  Time is not out when an appeal is being made.
(d) Effect of Preceding Runner's Failure to Touch a Base
Unless two are out, the status of a following runner is not affected
by a preceding runner's failure to touch or retouch a base. If, upon
appeal, the preceding runner is the third out, no runners following
him shall score. If such third out is the result of a force play, nei-
ther preceding nor following runners shall score.
(e) Retiring the Side
When three offensive players are legally put out, that team takes the
field and the opposing team becomes the offensive team.
5.10 Substitutions and Pitching Changes
(Including Visits to the Mound)
(a) A player, or players, may be substituted during a game at any
time the ball is dead.  A substitute player shall bat in the
replaced player's position in the team's batting order.
(b) The manager shall immediately notify the umpire-in-chief of
any substitution and shall state to the umpire-in-chief the sub-
stitute's place in the batting order.
Rule 5.10(b) Comment: To avoid any confusion, the manager
should give the name of the substitute, his position in the bat-
ting order and his position on the field.  When two or more
substitute players of the defensive team enter the game at the
same time, the manager shall, immediately before they take
their positions as fielders, designate to the umpire-in-chief
such players' positions in the team's batting order, and the
umpire-in-chief shall so notify the official scorer.  If this infor-
mation is not immediately given to the umpire-in-chief, the
umpire-in-chief shall have authority to designate the substi-
tutes' places in the batting order.

Rule 5.10(b) to 5.10(d)
51
If a double-switch is being made, the manager or coach shall
first notify the plate umpire.  The umpire-in-chief must be
informed of the multiple substitutions and interchanged batting
order before the manager calls for a new pitcher (regardless of
whether the manager or coach announces the double-switch
before crossing the foul line).  Signaling or motioning to the
bullpen is to be considered an official substitution for the new
pitcher.  It is not permissible for the manager to go to the
mound, call for a new pitcher, and then inform the umpire of
multiple substitutions with the intention of interchanging the
batting order.
Players for whom substitutions have been made may remain
with their team on the bench or may "warm-up" pitchers.  If a
manager substitutes another player for himself, he may con-
tinue to direct his team from the bench or the coach's box.
Umpires should not permit players for whom substitutes have
been made, and who are permitted to remain on the bench, to
address any remarks to any opposing player or manager, or to
the umpires.
(c) The umpire-in-chief, after having been notified, shall immedi-
ately announce, or cause to be announced, each substitution.
(d) A player once removed from a game shall not re-enter that
game.  If a player who has been substituted for attempts to re-
enter, or re-enters, the game in any capacity, the umpire-in-
chief shall direct the player's manager to remove such player
from the game immediately upon noticing the player's pres-
ence or upon being informed of the player's improper presence
by another umpire or by either manager.  If such direction to
remove the substituted for player occurs before play com-
mences with the player improperly in the game, then the sub-
stitute player may enter the game.  If such direction to remove
the substituted-for player occurs after play has commenced
with the substituted-for player in the game, then the substitute
player shall be deemed to have been removed from the game
(in addition to the removal of the substituted-for player) and
shall not enter the game.  If a substitute enters the game in
place of a player-manager, the manager may thereafter go to

the coaching lines at his discretion.  When two or more substi-
tute players of the defensive team enter the game at the same
time, the manager shall, immediately before they take their
positions as fielders, designate to the umpire-in-chief such
players' positions in the team's batting order and the umpire-in-
chief shall so notify the official scorer.  If this information is not
immediately given to the umpire-in-chief, he shall have author-
ity to designate the substitutes' places in the batting order.
Rule 5.10(d) Comment: A pitcher may change to another posi-
tion only once during the same inning; e.g. the pitcher will not
be allowed to assume a position other than a pitcher more than
once in the same inning.
Any player other than a pitcher substituted for an injured
player shall be allowed five warm-up throws. (See Rule
5.07(b) for pitchers.)
Any play that occurs while a player appears in a game after
having been substituted for shall count.  If, in an umpire's
judgment, the player re-entered the game knowing that he had
been removed, the umpire may eject the manager.
(e) A player whose name is on his team's batting order may not
become a substitute runner for another member of his team.
Rule 5.10(e) Comment: This rule is intended to eliminate the
practice of using so-called courtesy runners.  No player in the
game shall be permitted to act as a courtesy runner for a team-
mate.  No player who has been in the game and has been taken
out for a substitute shall return as a courtesy runner. Any player
not in the lineup, if used as a runner, shall be considered as a
substitute player.
(f ) The pitcher named in the batting order handed the umpire-in-
chief, as provided in Rules 4.02(a) and 4.02(b), shall pitch to
the first batter or any substitute batter until such batter is put
out or reaches first base, unless the pitcher sustains injury or ill-
ness which, in the judgment of the umpire-in-chief, incapaci-
tates him from pitching.
(g) If the pitcher is replaced, the substitute pitcher shall pitch to the
batter then at bat, or any substitute batter, until such batter is

put out or reaches first base, or until the offensive team is put
out, unless the substitute pitcher sustains injury or illness
which, in the umpire-in-chief's judgment, incapacitates him for
further play as a pitcher.
(h) If an improper substitution is made for the pitcher, the umpire
shall direct the proper pitcher to return to the game until the
provisions of this rule are fulfilled. If the improper pitcher is
permitted to pitch, any play that results is legal. The improper
pitcher becomes the proper pitcher as soon as he makes his first
pitch to the batter, or as soon as any runner is put out.
Rule 5.10(h ) Comment: If a manager attempts to remove a
pitcher in violation of Rule 5.10(h) the umpire shall notify the
manager of the offending club that it cannot be done.  If, by
chance, the umpire-in-chief has, through oversight, announced
the incoming improper pitcher, he should still correct the situa-
tion before the improper pitcher pitches.  Once the improper
pitcher delivers a pitch he becomes the proper pitcher.
(i) If a pitcher who is already in the game crosses the foul line on
his way to take his place on the pitcher's plate to start an
inning, he shall pitch to the first batter until such batter is put
out or reaches first base, unless the batter is substituted for, or
the pitcher sustains an injury or illness which, in the judgment
of the umpire-in-chief, incapacitates him from pitching.  If the
pitcher ends the previous inning on base or at bat and does not
return to the dugout after the inning is completed, the pitcher is
not required to pitch to the first batter of the inning until he
makes contact with the pitcher's plate to begin his warm-up
pitches.
( j) If no announcement of a substitution is made, the substitute
shall be considered as having entered the game when:
(1) If a pitcher, he takes his place on the pitcher's plate;
(2) If a batter, he takes his place in the batter's box;
(3) If a fielder, he reaches the position usually occupied by
the fielder he has replaced, and play commences;
(4) If a runner, he takes the place of the runner he has
replaced.

Rule 5.10(j) to 5.10(l)
54
Any play made by, or on, any of the above mentioned unannounced
substitutes shall be legal.
(k) Players and substitutes of both teams shall confine themselves
to their team's benches unless actually participating in the play
or preparing to enter the game, or coaching at first or third base.
No one except players, substitutes, managers, coaches, trainers
and bat boys shall occupy a bench during a game.
PENALTY: For violation the umpire may, after warning,
remove the offender from the field.
Rule 5.10(k) Comment: Players on the disabled list are permit-
ted to participate in pre-game activity and sit on the bench dur-
ing a game but may not take part in any activity during the
game such as warming up a pitcher, bench-jockeying, etc.
Disabled players are not allowed to enter the playing surface at
any time or for any purpose during the game.
(l) Visits to the Mound Requiring a Pitcher's Removal
From the Game
A professional league shall adopt the following rule pertaining to
the visit of the manager or coach to the pitcher:
(1) This rule limits the number of trips a manager or coach
may make to any one pitcher in any one inning;
(2) A second trip to the same pitcher in the same inning will
cause this pitcher's automatic removal from the game;
(3) The manager or coach is prohibited from making a sec-
ond visit to the mound while the same batter is at bat, but
(4) if a pinch-hitter is substituted for this batter, the manager
or coach may make a second visit to the mound, but must
remove the pitcher from the game.
A manager or coach is considered to have concluded his visit to the
mound when he leaves the 18-foot circle surrounding the pitcher's
rubber.
Rule 5.10(l) Comment: If the manager or coach goes to the
catcher or infielder and that player then goes to the mound or

the pitcher comes to him at his position before there is an inter-
vening play (a pitch or other play) that will be the same as the
manager or coach going to the mound.
Any attempt to evade or circumvent this rule by the manager or
coach going to the catcher or an infielder and then that player
going to the mound to confer with the pitcher shall constitute a
trip to the mound.
If the coach goes to the mound and removes a pitcher and then
the manager goes to the mound to talk with the new pitcher,
that will constitute one trip to that new pitcher that inning.
A manager or coach shall not be considered to have concluded
his visit to the mound if he temporarily leaves the 18-foot cir-
cle surrounding the pitcher's rubber for purposes of notifying
the umpire that a double-switch or substitution is being made.
In a case where a manager has made his first trip to the mound
and then returns the second time to the mound in the same
inning with the same pitcher in the game and the same batter at
bat, after being warned by the umpire that he cannot return to
the mound, the manager shall be removed from the game and
the pitcher required to pitch to the batter until he is retired or
gets on base.  After the batter is retired, or becomes a base run-
ner, then this pitcher must be removed from the game.  The
manager should be notified that his pitcher will be removed
from the game after he pitches to one hitter, so he can have a
substitute pitcher warmed up.  In such circumstance, the sub-
stitute pitcher will be allowed as much time to throw prepara-
tory pitches as in the umpire's judgment circumstances justify.
(m) Limitation on the Number of Mound Visits Per Game
The following rule shall apply in Major League games.  National
Association Leagues may adopt a rule providing for a different lim-
itation on the number of mound visits permitted in a game or no
limitation on the number of mound visits.
(1) Mound visits without a pitching change shall be limited
to six per team, per nine innings.  For any extra-innings
played, each team shall be entitled to one additional non-
pitching change mound visit per inning.

Rule 5.11(m)(2) to Rule 5.11(a)(1)
56
(2) For purposes of this Rule 5.10(m), a manager or coach
trip to the mound to meet with the pitcher shall constitute
a visit.  A player leaving his position to confer with the
pitcher, including a pitcher leaving the mound to confer
with another player, shall also constitute a visit, regard-
less of where the visit occurs or the length of the visit,
except that the following shall not constitute visits:
(A) Discussions between pitchers and position player(s)
that occur between batters in the normal course of
play and do not require either the position player(s)
or the pitcher to relocate;
(B) Visits by position players to the mound to clean
spikes in rainy conditions;
(C) Visits to the mound due to an injury or potential
injury of the pitcher; and
(D) Visits to the mound after the announcement of an
offensive substitution.
(3) Cross Up in Signs.  In the event a team has exhausted its
allotment of mound visits in a game (or extra inning) and
the home plate umpire determines that the catcher and
pitcher did not have a shared understanding of the loca-
tion or type of pitch that had been signaled by the catcher
(otherwise referred to as a "cross up"), the home plate
umpire may, upon request of the catcher, allow the
catcher to make a brief mound visit.  However, any
mound visit resulting from a "cross up" prior to a team
exhausting its allotted number of visits shall count
against a team's total number of allotted mound visits.
5.11 Designated Hitter Rule
Any League may elect to use Rule 5.11(a), which shall be called
the Designated Hitter Rule.
(a) The Designated Hitter Rule provides as follows:
(1) A hitter may be designated to bat for the starting pitcher
and all subsequent pitchers in any game without other-

wise affecting the status of the pitcher(s) in the game. A
Designated Hitter for the pitcher, if any, must be selected
prior to the game and must be included in the lineup cards
presented to the Umpire-in-Chief.  If a manager lists 10
players in his team's lineup card, but fails to indicate one
as the Designated Hitter, and an umpire or either manager
(or designee of either manager who presents his team's
lineup card) notices the error before the umpire-in-chief
calls "Play" to start the game, the umpire-in-chief shall
direct the manager who had made the omission to desig-
nate which of the nine players, other than the pitcher, will
be the Designated Hitter.
Rule 5.11(a)(1) Comment: A correction of a failure to indicate
a Designated Hitter when 10 players are listed in a batting
order is an "obvious" error that may be corrected before a
game starts.  See Rule 4.03 Comment.
(2) The Designated Hitter named in the starting lineup must
come to bat at least one time, unless the opposing club
changes pitchers.
(3) It is not mandatory that a club designate a hitter for the
pitcher, but failure to do so prior to the game precludes
the use of a Designated Hitter for that club for that
game.
(4) Pinch-hitters for a Designated Hitter may be used.  Any
substitute hitter for a Designated Hitter becomes the
Designated Hitter.  A replaced Designated Hitter shall not
re-enter the game in any capacity.
(5) The Designated Hitter may be used on defense, continu-
ing to bat in the same position in the batting order, but the
pitcher must then bat in the place of the substituted defen-
sive player, unless more than one substitution is made,
and the manager then must designate their spots in the
batting order.
(6) A runner may be substituted for the Designated Hitter
and the runner assumes the role of Designated Hitter.  A
Designated Hitter may not pinch-run.

(7) A Designated Hitter is "locked" into the batting order. No
multiple substitutions may be made that will alter the bat-
ting rotation of the Designated Hitter.
(8) Once the game pitcher is switched from the mound to a posi-
tion on defense, such move shall terminate the Designated
Hitter role for that club for the remainder of the game.
(9) Once a pinch-hitter bats for any player in the batting
order and then enters the game to pitch, such move shall
terminate the Designated Hitter role for that club for the
remainder of the game.
(10) Once the game pitcher bats or runs for the Designated
Hitter, such move shall terminate the Designated Hitter
role for that club for the remainder of the game.  The
game pitcher may pinch-hit or pinch-run only for the
Designated Hitter.
(11) If a manager lists 10 players in his team's lineup card, but
fails to indicate one as the Designated Hitter, and the
opposing manager brings the failure to list a Designated
Hitter to the attention of the umpire-in-chief after the
game starts, then
(A) the pitcher will be required to bat in the batting
order in the place of the listed player who has not
assumed a position on defense, if the team has
taken the field on defense, or
(B) if the team has not yet taken the field on defense,
the pitcher will be placed in the batting order in
place of any player, as chosen by the manager of
that team.
In either case, the player whom the pitcher replaces in the batting
order shall be considered to have been substituted for and is
removed from the game and the Designated Hitter role for that club
shall be terminated for the remainder of the game. Any play that
occurred before the violation is brought to the attention of the
umpire-in-chief shall count, subject to Rule 6.03(b).

(12) Once a Designated Hitter assumes a position on defense,
such move shall terminate the Designated Hitter role for

(13) A substitute for the Designated Hitter need not be
announced until it is the Designated Hitter's turn to
bat.
(14) If a player on defense goes to the mound (i.e., replaces
the pitcher), this move shall terminate the Designated
Hitter's role for that club for the remainder of the
game.
(15) The Designated Hitter may not sit in the bullpen unless
serving as a catcher in the bullpen.
(b) In the event of inter-league competition between clubs of
leagues using the Designated Hitter Rule and clubs of leagues not
using the Designated Hitter Rule, the rule will be used as follows:
(1) In World Series or exhibition games, the rule will be used
or not used as is the practice of the league of the home
team.
(2) In All-Star games, the rule will only be used if both teams
and both Leagues so agree.
5.12 Calling "Time" and Dead Balls
(a) When an umpire suspends play, he shall call "Time." At the
umpire-in-chief's call of "Play," the suspension is lifted and
play resumes. Between the call of "Time" and the call of
"Play" the ball is dead.
(b) The ball becomes dead when an umpire calls "Time." The
umpire-in-chief shall call "Time:
(1) When in his judgment weather, darkness or similar condi-
tions make immediate further play impossible;
(2) When light failure makes it difficult or impossible for the
umpires to follow the play;

Rule 5.12(b)(2) to 5.12(b)(8)
60
NOTE: A league may adopt its own regulations govern-
ing games interrupted by light failure.
(3) When an accident incapacitates a player or an umpire;
(A) If an accident to a runner is such as to prevent
him from proceeding to a base to which he is
entitled, as on a home run hit out of the playing
field, or an award of one or more bases, a substi-
tute runner shall be permitted to complete the
play.
(4) When a manager requests "Time" for a substitution, or
for a conference with one of his players.
(5) When the umpire wishes to examine the ball, to consult
with either manager, or for any similar cause.
(6) When a fielder, after catching a fly ball, steps or falls into
any out-of-play area.  All other runners shall advance one
base, without liability to be put out, from his last legally
touched base at the time the fielder entered such out-of-
play area.
(7) When an umpire orders a player or any other person
removed from the playing field.
(8) Except in the cases stated in paragraphs (2) and (3)(A) of
this rule, no umpire shall call "Time" while a play is in
progress.
After the ball is dead, play shall be resumed when the pitcher takes
his place on the pitcher's plate with a new ball or the same ball in
his possession and the plate umpire calls "Play."  The plate umpire
shall call "Play" as soon as the pitcher takes his place on his plate
with the ball in his possession.

Rule 6.01(a)
61
6.00 IMPROPER PLAY, ILLEGAL ACTION, 
AND MISCONDUCT
6.01 Interference, Obstruction, and Catcher Collisions
(a) Batter or Runner Interference
It is interference by a batter or a runner when:
(1) After a third strike that is not caught by the catcher, the
batter-runner clearly hinders the catcher in his attempt to
field the ball.  Such batter-runner is out, the ball is dead,
and all other runners return to the bases they occupied at
the time of the pitch;
Rule 6.01(a)(1) Comment: If the pitched ball deflects off the
catcher or umpire and subsequently touches the batter-runner,
it is not considered interference unless, in the judgment of the
umpire, the batter-runner clearly hinders the catcher in his
attempt to field the ball.
(2) He intentionally deflects the course of a foul ball in any
manner;
(3) Before two are out and a runner on third base, the batter
hinders a fielder in making a play at home base; the run-
ner is out;
(4) Any member or members of the offensive team stand or
gather around any base to which a runner is advancing, to
confuse, hinder or add to the difficulty of the fielders.
Such runner shall be declared out for the interference of
his teammate or teammates;
(5) Any batter or runner who has just been put out, or any
runner who has just scored, hinders or impedes any fol-
lowing play being made on a runner.  Such runner shall
be declared out for the interference of his teammate (see
Rule 6.01(j));
Rule 6.01(a )(5) Comment: If the batter or a runner continues to
advance or returns or attempts to return to his last legally touched
base after he has been put out, he shall not by that act alone be
considered as confusing, hindering or impeding the fielders.

Rule 6.01(a)(6) to 6.01(a)(10)
62
(6) If, in the judgment of the umpire, a base runner willfully
and deliberately interferes with a batted ball or a fielder
in the act of fielding a batted ball with the obvious intent
to break up a double play, the ball is dead. The umpire
shall call the runner out for interference and also call out
the batter-runner because of the action of his teammate.
In no event may bases be run or runs scored because of
such action by a runner (see Rule 6.01(j));
(7) If, in the judgment of the umpire, a batter-runner willfully
and deliberately interferes with a batted ball or a fielder
in the act of fielding a batted ball, with the obvious intent
to break up a double play, the ball is dead; the umpire
shall call the batter-runner out for interference and shall
call out the runner who had advanced closest to the home
plate regardless where the double play might have been
possible. In no event shall bases be run because of such
interference (see Rule 6.01(j));
(8) In the judgment of the umpire, the base coach at third
base, or first base, by touching or holding the runner,
physically assists him in returning to or leaving third base
or first base;
(9) With a runner on third base, the base coach leaves his box
and acts in any manner to draw a throw by a fielder;
(10) He fails to avoid a fielder who is attempting to field a bat-
ted ball, or intentionally interferes with a thrown ball,
provided that if two or more fielders attempt to field a
batted ball, and the runner comes in contact with one or
more of them, the umpire shall determine which fielder is
entitled to the benefit of this rule, and shall not declare
the runner out for coming in contact with a fielder other
than the one the umpire determines to be entitled to field
such a ball.  The umpire shall call the runner out in accor-
dance with Rule 5.09(b)(3) (former Rule 7.08(b)).  If the
batter-runner is adjudged not to have hindered a fielder
attempting to make a play on a batted ball, and if the base
runner's interference is adjudged not to be intentional, the
batter-runner shall be awarded first base;

Rule 6.01(a)(10) to 6.01(a)(11)
63
Rule 6.01(a )(10) Comment:  When a catcher and batter-runner
going to first base have contact when the catcher is fielding the
ball, there is generally no violation and nothing should be
called. "Obstruction" by a fielder attempting to field a ball
should be called only in very flagrant and violent cases
because the rules give him the right of way, but of course such
"right of way" is not a license to, for example, intentionally
trip a runner even though fielding the ball.  If the catcher is
fielding the ball and any fielder, including the pitcher, obstructs
a runner going to first base, "obstruction" shall be called and
the base runner awarded first base.
(11) A fair ball touches him on fair territory before touching a
fielder. If a fair ball goes through, or by, an infielder, and
touches a runner immediately back of him, or touches the
runner after having been deflected by a fielder, the
umpire shall not declare the runner out for being touched
by a batted ball. In making such decision the umpire must
be convinced that the ball passed through, or by, the
fielder, and that no other infielder had the chance to make
a play on the ball. If, in the judgment of the umpire, the
runner deliberately and intentionally kicks such a batted
ball on which the infielder has missed a play, then the
runner shall be called out for interference.
PENALTY FOR INTERFERENCE: The runner is out
and the ball is dead.
If the umpire declares the batter, batter-runner, or a run-
ner out for interference, all  other runners shall return to the last
base that was in the judgment of the umpire, legally touched at
the time of the interference, unless otherwise provided by these
rules.
In the event the batter-runner has not reached first base,
all runners shall return to the base last occupied at the time of
the pitch; provided, however, if during an intervening play at the
plate with less than two outs a runner scores, and then the batter-
runner is called out for interference outside the three-foot lane,
the runner is safe and the run shall count.

Rule 6.01(a) to 6.01(b)

Rule 6.01(a) Penalty for Interference Comment: A runner who
is adjudged to have hindered a fielder who is attempting to
make a play on a batted ball is out whether it was intentional or
not.
If, however, the runner has contact with a legally occupied base
when he hinders the fielder, he shall not be called out unless, in
the umpire's judgment, such hindrance, whether it occurs on
fair or foul territory, is intentional.  If the umpire declares the
hindrance intentional, the following penalty shall apply:  With
less than two out, the umpire shall declare both the runner and
batter out.  With two out, the umpire shall declare the batter
out.
If, in a run-down between third base and home plate, the suc-
ceeding runner has advanced and is standing on third base
when the runner in a run-down is called out for offensive inter-
ference, the umpire shall send the runner standing on third base
back to second base.
This same principle applies if there is a run-down between sec-
ond and third base and succeeding runner has reached second
(the reasoning is that no runner shall advance on an interfer-
ence play and a runner is considered to occupy a base until he
legally has reached the next succeeding base).
(b) Fielder Right of Way
The players, coaches or any member of a team at bat shall vacate
any space (including both dugouts or bullpens) needed by a fielder
who is attempting to field a batted or thrown ball. If a member of the
team at bat (other than a runner) hinders a fielder's attempt to catch
or field a batted ball, the ball is dead, the batter is declared out and
all runners return to the bases occupied at the time of the pitch. If a
member of the team at bat (other than a runner) hinders a fielder's
attempt to field a thrown ball, the ball is dead, the runner on whom
the play is being made shall be declared out and all runners return to
the last legally occupied base at the time of the interference.
Rule 6.01(b) Comment: Defensive interference is an act by a
fielder that hinders or prevents a batter from hitting a pitch.

Rule 6.01(c)
65
(c) Catcher Interference
The batter becomes a runner and is entitled to first base without lia-
bility to be put out (provided he advances to and touches first base)
when the catcher or any fielder interferes with him.  If a play fol-
lows the interference, the manager of the offense may advise the
plate umpire that he elects to decline the interference penalty and
accept the play.  Such election shall be made immediately at the
end of the play.  However, if the batter reaches first base on a hit, an
error, a base on balls, a hit batsman, or otherwise, and all other run-
ners advance at least one base, the play proceeds without reference
to the interference.
Rule 6.01(c) Comment: If catcher's interference is called with a
play in progress the umpire will allow the play to continue
because the manager may elect to take the play. If the batter-
runner missed first base, or a runner misses his next base, he
shall be considered as having reached the base, as stated in Note
of Rule 5.06(b)(3)(D).
Examples of plays the manager might elect to take:
1. Runner on third, one out, batter hits fly ball to the outfield
on which the runner scores but catcher's interference was
called. The offensive manager may elect to take the run
and have batter called out or have runner remain at third
and batter awarded first base.
2. Runner on second base. Catcher interferes with batter. As
he bunts ball fairly sending runner to third base. The
manager may rather have runner on third base with an out
on the play than have runners on second and first.
If a runner is trying to score by a steal or squeeze from
third base, note the additional penalty set forth in Rule
6.01(g).
If the catcher interferes with the batter before the pitcher
delivers the ball, it shall not be considered interference on
the batter under Rule 5.05 (b) (3).  In such cases, the
umpire shall call "Time" and the pitcher and batter start
over from "scratch."

Rule 6.01(d)
66
(d) Unintentional Interference
In case of unintentional interference with play by any person herein
authorized to be on the playing field (except members of the team
at bat who are participating in the game, or a base coach, any of
whom interfere with a fielder attempting to field a batted or thrown
ball; or an umpire) the ball is alive and in play.  If the interference
is intentional, the ball shall be dead at the moment of the interfer-
ence and the umpire shall impose such penalties as in his opinion
will nullify the act of interference.
Rule 6.01(d) Comment: For interference with a fielder
attempting to field a batted or thrown ball by members of the
team at bat or base coaches, who are excepted in Rule 6.01(d),
see Rule 6.01(b).  See also Rules 5.06(c)(2), 5.06(c)(6) and
5.05(b)(4), which cover interference by an umpire, and Rule
5.09(b)(3), which covers interference by a runner.
The question of intentional or unintentional interference shall
be decided on the basis of the person's action.  For example: a
bat boy, ball attendant, policeman, etc., who tries to avoid
being touched by a thrown or batted ball but still is touched by
the ball would be involved in unintentional interference.  If,
however, he kicks the ball or picks it up or pushes it, that is
considered intentional interference, regardless of what his
thought may have been.
PLAY: Batter hits ball to shortstop, who fields ball but throws
wild past first baseman.  The coach at first base, to avoid being
hit by the ball, falls to the ground and the first baseman on his
way to retrieve the wild thrown ball, runs into the coach.  The
batter-runner finally ends up on third base. Whether the umpire
should call interference on the part of the coach is up to the
judgment of the umpire and if the umpire felt that the coach did
all he could to avoid interfering with the play, no interference
need be called. If, in the judgment of the umpire, the coach was
attempting to make it appear that he was trying not to interfere,
the umpire should rule interference.

Rule 6.01(e)
67
(e) Spectator Interference
When there is spectator interference with any thrown or batted ball,
the ball shall be dead at the moment of interference and the umpire
shall impose such penalties as in his opinion will nullify the act of
interference.
APPROVED RULING: If spectator interference clearly pre-
vents a fielder from catching a fly ball, the umpire shall declare
the batter out.
Rule 6.01(e) Comment: There is a difference between a ball
which has been thrown or batted into the stands, touching a
spectator thereby being out of play even though it rebounds
onto the field and a spectator going onto the field or reaching
over, under or through a barrier and touching a ball in play or
touching or otherwise interfering with a player.  In the latter
case it is clearly intentional and shall be dealt with as inten-
tional interference as in Rule 6.01(d).  Batter and runners shall
be placed where in the umpire's judgment they would have
been had the interference not occurred.
No interference shall be allowed when a fielder reaches over a
fence, railing, rope or into a stand to catch a ball. He does so at
his own risk. However, should a spectator reach out on the
playing field side of such fence, railing or rope, and plainly
prevent the fielder from catching the ball, then the batsman
should be called out for the spectator's interference.
EXAMPLE: Runner on third base, one out and a batter hits a
fly ball deep to the outfield (fair or foul). Spectator clearly
interferes with the outfielder attempting to catch the fly ball.
Umpire calls the batter out for spectator interference. Ball is
dead at the time of the call. Umpire decides that because of the
distance the ball was hit, the runner on third base would have
scored after the catch if the fielder had caught the ball which
was interfered with, therefore, the runner is permitted to score.
This might not be the case if such fly ball was interfered with a
short distance from home plate.

Rule 6.01(f) to 6.01(h)
68
(f ) Coach and Umpire Interference
If a thrown ball accidentally touches a base coach, or a pitched or
thrown ball touches an umpire, the ball is alive and in play.
However, if the coach interferes with a thrown ball, the runner is out.
Rule 6.01( f ) Comment: Umpire's interference occurs (1)
when a plate umpire hinders, impedes or prevents a catcher's
throw attempting to prevent a stolen base or retire a runner on
a pick-off play; or (2) when a fair ball touches an umpire on
fair territory before passing a fielder.  Umpire interference may
also occur when an umpire interferes with a catcher returning
the ball to the pitcher.
(g) Interference With Squeeze Play or Steal of Home
If, with a runner on third base and trying to score by means of a
squeeze play or a steal, the catcher or any other fielder steps on, or
in front of home base without possession of the ball, or touches the
batter or his bat, the pitcher shall be charged with a balk, the batter
shall be awarded first base on the interference and the ball is dead.
(h) Obstruction
When obstruction occurs, the umpire shall call or signal
"Obstruction."
(1) If a play is being made on the obstructed runner, or if the
batter-runner is obstructed before he touches first base,
the ball is dead and all runners shall advance, without lia-
bility to be put out, to the bases they would have reached,
in the umpire's judgment, if there had been no obstruc-
tion. The obstructed runner shall be awarded at least one
base beyond the base he had last legally touched before
the obstruction. Any preceding runners, forced to
advance by the award of bases as the penalty for obstruc-
tion, shall advance without liability to be put out.
Rule 6.01(h )(1) Comment: When a play is being made on an
obstructed runner, the umpire shall signal obstruction in the
same manner that he calls "Time," with both hands overhead.
The ball is immediately dead when this signal is given; how-
ever, should a thrown ball be in flight before the obstruction is

Rule 6.01(h)
69
called by the umpire, the runners are to be awarded such bases
on wild throws as they would have been awarded had not
obstruction occurred. On a play where a runner was trapped
between second and third and obstructed by the third baseman
going into third base while the throw is in flight from the short-
stop, if such throw goes into the dugout the obstructed runner
is to be awarded home base. Any other runners on base in this
situation would also be awarded two bases from the base they
last legally touched before obstruction was called.
(2) If no play is being made on the obstructed runner, the play
shall proceed until no further action is possible. The
umpire shall then call "Time" and impose such penalties,
if any, as in his judgment will nullify the act of obstruction.
Rule 6.01(h)(2) Comment: Under Rule 6.01(h)(2), when the
ball is not dead on obstruction and an obstructed runner
advances beyond the base which, in the umpire's judgment, he
would have been awarded because of being obstructed, he does
so at his own peril and may be tagged out.  This is a judgment
call.
NOTE: The catcher, without the ball in his possession, has no
right to block the pathway of the runner attempting to score.
The base line belongs to the runner and the catcher should be
there only when he is fielding a ball or when he already has the
ball in his hand.
Rule 6.01(h ) Comment:  If a fielder is about to receive a
thrown ball and if the ball is in flight directly toward and near
enough to the fielder so he must occupy his position to receive
the ball he may be considered "in the act of fielding a ball." It
is entirely up to the judgment of the umpire as to whether a
fielder is in the act of fielding a ball.  After a fielder has made
an attempt to field a ball and missed, he can no longer be in the
"act of fielding" the ball.  For example:  An infielder dives at a
ground ball and the ball passes him and he continues to lie on
the ground and delays the progress of the runner, he very likely
has obstructed the runner.

(i) Collisions at Home Plate
(1) A runner attempting to score may not deviate from his direct
pathway to the plate in order to initiate contact with the catcher
(or other player covering home plate), or otherwise initiate an
avoidable collision.  If, in the judgment of the umpire, a runner
attempting to score initiates contact with the catcher (or other
player covering home plate) in such a manner, the umpire shall
declare the runner out (regardless of whether the player cover-
ing home plate maintains possession of the ball).  In such cir-
cumstances, the umpire shall call the ball dead, and all other
base runners shall return to the last base touched at the time of
the collision.  If the runner slides into the plate in an appropriate
manner, he shall not be adjudged to have violated Rule 6.01(i).
Rule 6.01(i )(1) Comment: The failure by the runner to make
an effort to touch the plate, the runner's lowering of the shoul-
der, or the runner's pushing through with his hands, elbows or
arms, would support a determination that the runner deviated
from the pathway in order to initiate contact with the catcher in
violation of Rule 6.01(i), or otherwise initiated a collision that
could have been avoided.  A slide shall be deemed appropriate,
in the case of a feet first slide, if the runner's buttocks and legs
should hit the ground before contact with the catcher.  In the
case of a head first slide, a runner shall be deemed to have slid
appropriately if his body should hit the ground before contact
with the catcher.  If a catcher blocks the pathway of the runner,
the umpire shall not find that the runner initiated an avoidable
collision in violation of this Rule 6.01(i)(1).
(2) Unless the catcher is in possession of the ball, the catcher can-
not block the pathway of the runner as he is attempting to score.
If, in the judgment of the umpire, the catcher without posses-
sion of the ball blocks the pathway of the runner, the umpire
shall call or signal the runner safe.  Not withstanding the above,
it shall not be considered a violation of this Rule 6.01(i)(2) if
the catcher blocks the pathway of the runner in a legitimate
attempt to field the throw (e.g., in reaction to the direction, tra-
jectory or the hop of the incoming throw, or in reaction to a
throw that originates from a pitcher or drawn-in infielder).  In
addition, a catcher without possession of the ball shall not be

adjudged to violate this Rule 6.01(i)(2) if the runner could have
avoided the collision with the catcher (or other player covering
home plate) by sliding.
Rule 6.01(i)(2) Comment: A catcher shall not be deemed to
have violated Rule 6.01(i)(2) unless he has both blocked the
plate without possession the ball (or when not in a legitimate
attempt to field the throw), and also hindered or impeded the
progress of the runner attempting to score.  A catcher shall not
be deemed to have hindered or impeded the progress of the
runner if, in the judgment of the umpire, the runner would have
been called out notwithstanding the catcher having blocked the
plate.  In addition, a catcher should use best efforts to avoid
unnecessary and forcible contact while tagging a runner
attempting to slide.  Catchers who routinely make unnecessary
and forcible contact with a runner attempting to slide (e.g., by
initiating contact using a knee, shin guard, elbow or forearm)
may be subject to discipline by the League President.
This Rule 6.01(i)(2) shall not apply to force plays at home plate.
(j) Sliding to Bases on Double Play Attempts
If a runner does not engage in a bona fide slide, and initiates (or
attempts to make) contact with the fielder for the purpose of break-
ing up a double play, he should be called for interference under this
Rule 6.01.  A "bona fide slide" for purposes of Rule 6.01 occurs
when the runner: 
(1) begins his slide (i.e., makes contact with the ground) before
reaching the base; 
(2) is able and attempts to reach the base with his hand or foot; 
(3) is able and attempts to remain on the base (except home
plate) after completion of the slide; and 
(4) slides within reach of the base without changing his path-
way for the purpose of initiating contact with a fielder. 
A runner who engages in a "bona fide slide" shall not be called for
interference under this Rule 6.01, even in cases where the runner
makes contact with the fielder as a consequence of a permissible

slide.  In addition, interference shall not be called where a runner's
contact with the fielder was caused by the fielder being positioned
in (or moving into) the runner's legal pathway to the base.
Notwithstanding the above, a slide shall not be a "bona fide slide"
if a runner engages in a "roll block," or intentionally initiates (or
attempts to initiate) contact with the fielder by elevating and kick-
ing his leg above the fielder's knee or throwing his arm or his upper
body.
If the umpire determines that the runner violated this Rule 6.01(j),
the umpire shall declare both the runner and batter-runner out.
Note, however, that if the runner has already been put out then the
runner on whom the defense was attempting to make a play shall be
declared out.
6.02 Pitcher Illegal Action
(a) Balks
If there is a runner, or runners, it is a balk when:
(1) The pitcher, while touching his plate, makes any motion
naturally associated with his pitch and fails to make such
delivery;
Rule 6.02(a )(1) Comment: If a left-handed or right-handed
pitcher swings his free foot past the back edge of the pitcher's
rubber, he is required to pitch to the batter except to throw to
second base on a pick-off play.
(2) The pitcher, while touching his plate, feints a throw to
first or third base and fails to complete the throw;
(3) The pitcher, while touching his plate, fails to step directly
toward a base before throwing to that base;
Rule 6.02(a )(3) Comment: Requires the pitcher, while touch-
ing his plate, to step directly toward a base before throwing to
that base.  If a pitcher turns or spins off of his free foot without
actually stepping or if he turns his body and throws before
stepping, it is a balk.
A pitcher is to step directly toward a base before throwing to
that base and is required to throw (except to second base)

because he steps.  It is a balk if, with runners on first and third,
the pitcher steps toward third and does not throw, merely to
bluff the runner back to third; then seeing the runner on first
start for second, turn and step toward and throw to first base.  It
is legal for a pitcher to feint a throw to second base.
(4) The pitcher, while touching his plate, throws, or feints a
throw to an unoccupied base, except for the purpose of
making a play;
Rule 6.02 (a )(4) Comment: When determining whether the
pitcher throws or feints a throw to an unoccupied base for the
purpose of making a play, the umpire should consider whether
a runner on the previous base demonstrates or otherwise cre-
ates an impression of his intent to advance to such unoccupied
base.
(5) The pitcher makes an illegal pitch;
Rule 6.02(a )(5) Comment: A quick pitch is an illegal pitch.
Umpires will judge a quick pitch as one delivered before the
batter is reasonably set in the batter's box.  With runners on
base the penalty is a balk; with no runners on base, it is a ball.
The quick pitch is dangerous and should not be permitted.
(6) The pitcher delivers the ball to the batter while he is not
facing the batter;
(7) The pitcher makes any motion naturally associated with
his pitch while he is not touching the pitcher's plate;
(8) The pitcher unnecessarily delays the game;
Rule 6.02(a)(8) Comment: Rule 6.02 (a)(8) shall not apply
when a warning is given pursuant to Rule 6.02(c)(8) (which
prohibits intentional delay of a game by throwing to fielders
not in an attempt to put a runner out).  If a pitcher is ejected
pursuant to Rule 6.02(c)(8) for continuing to delay the game,
the penalty in Rule 6.02(a)(8) shall also apply.  Rule 5.07(c)
(which sets a time limit for a pitcher to deliver the ball when
the bases are unoccupied) applies only when there are no run-
ners on base.

Rule 6.02(a)(9) to 6.02(a)(13)
74
(9) The pitcher, without having the ball, stands on or astride
the pitcher's plate or while off the plate, he feints a pitch;
(10) The pitcher, after coming to a legal pitching position,
removes one hand from the ball other than in an actual
pitch, or in throwing to a base;
(11) The pitcher, while touching his plate, accidentally or inten-
tionally has the ball slip or fall out of his hand or glove;
(12) The pitcher, while giving an intentional base on balls,
pitches when the catcher is not in the catcher's box;
(13) The pitcher delivers the pitch from Set Position without
coming to a stop.
PENALTY: The ball is dead, and each runner shall advance one
base without liability to be put out, unless the batter reaches
first on a hit, an error, a base on balls, a hit batter, or otherwise,
and all other runners advance at least one base, in which case
the play proceeds without reference to the balk.
APPROVED RULING: In cases where a pitcher balks and
throws wild, either to a base or to home plate, a runner or run-
ners may advance beyond the base to which he is entitled at his
own risk.
APPROVED RULING: A runner who misses the first base to
which he is advancing and who is called out on appeal shall be
considered as having advanced one base for the purpose of this
rule.
Rule 6.02(a ) Comment: Umpires should bear in mind that the
purpose of the balk rule is to prevent the pitcher from deliber-
ately deceiving the base runner. If there is doubt in the
umpire's mind, the "intent" of the pitcher should govern.
However, certain specifics should be borne in mind:
(A) Straddling the pitcher's rubber without the ball is to be
interpreted as intent to deceive and ruled a balk.
(B) With a runner on first base the pitcher may make a com-
plete turn, without hesitating toward first, and throw to
second. This is not to be interpreted as throwing to an
unoccupied base.

Rule 6.02(b) to 6.02(c)(6)
75
(b) Illegal Pitches With Bases Unoccupied
If the pitcher makes an illegal pitch with the bases unoccupied, it
shall be called a ball unless the batter reaches first base on a hit, an
error, a base on balls, a hit batter or otherwise.
Rule 6.02(b) Comment: A ball which slips out of a pitcher's
hand and crosses the foul line shall be called a ball; otherwise
it will be called no pitch.  This would be a balk with men on
base.
(c) Pitching Prohibitions
The pitcher shall not:
(1) While in the 18-foot circle surrounding the pitcher's
plate, touch the ball after touching his mouth or lips, or
touch his mouth or lips while he is in contact with the
pitcher's plate. The pitcher must clearly wipe the fingers
of his pitching hand dry before touching the ball or the
pitcher's plate.
EXCEPTION: Provided it is agreed to by both managers,
the umpire prior to the start of a game played in cold
weather, may permit the pitcher to blow on his hand.
PENALTY: For violation of this part of this rule the umpires
shall immediately remove the ball from play and issue a
warning to the pitcher. Any subsequent violation shall be
called a ball.  However, if the pitch is made and a batter
reaches first base on a hit, an error, a hit batsman or other-
wise, and no other runner is put out before advancing at
least one base, the play shall proceed without reference to
the violation.  Repeat offenders shall be subject to a fine by
the League President.
(2) expectorate on the ball, either hand or his glove; 
(3) rub the ball on his glove, person or clothing;
(4) apply a foreign substance of any kind to the ball; 
(5) deface the ball in any manner; or
(6) deliver a ball altered in a manner prescribed by Rule
6.02(c)(2) through (5) or what is called the "shine" ball,

"spit" ball, "mud" ball or "emery" ball. The pitcher is
allowed to rub the ball between his bare hands.
(7) Have on his person, or in his possession, any foreign sub-
stance.
Rule 6.02(c)(7) Comment: The pitcher may not attach any-
thing to either hand, any finger or either wrist (e.g., Band-Aid,
tape, Super Glue, bracelet, etc.).  The umpire shall determine if
such attachment is indeed a foreign substance for the purpose
of Rule 6.02(c)(7), but in no case may the pitcher be allowed to
pitch with such attachment to his hand, finger or wrist.
(8) Intentionally delay the game by throwing the ball to play-
ers other than the catcher, when the batter is in position,
except in an attempt to retire a runner.
PENALTY: If, after warning by the umpire, such delaying
action is repeated, the pitcher shall be removed from the game.
(9) Intentionally Pitch at the Batter.
(1) If, in the umpire's judgment, such a violation occurs, the
umpire may elect either to:
(A) Expel the pitcher, or the manager and the pitcher,
from the game, or
(B) may warn the pitcher and the manager of both
teams that another such pitch will result in the
immediate expulsion of that pitcher (or a replace-
ment) and the manager.
If, in the umpire's judgment, circumstances warrant, both
teams may be officially "warned" prior to the game or at
any time during the game.
(League Presidents may take additional action under
authority provided in Rule 8.04.)
Rule 6.02(c)(9) Comment: Team personnel may not come onto
the playing surface to argue or dispute a warning issued under
Rule 6.02 (c)(9).  If a manager, coach or player leaves the
dugout or his position to dispute a warning, he should be
warned to stop. If he continues, he is subject to ejection.

To pitch at a batter's head is unsportsmanlike and highly danger-
ous. It should beand iscondemned by everybody. Umpires
should act without hesitation in enforcement of this rule.
(d) PENALTY: For violation of any part of (c)(2) through (7):
(1) The pitcher shall be ejected immediately from the
game and shall be suspended automatically.  In
National Association Leagues, the automatic suspen-
sion shall be for 10 games.
(2) If a play follows the violation called by the umpire,
the manager of the team at bat may advise the
umpire-in-chief that he elects to accept the play.
Such election shall be made immediately at the end
of the play. However, if the batter reaches first base
on a hit, an error, a base on balls, a hit batsman, or
otherwise, and no other runner is put out before
advancing at least one base, the play shall proceed
without reference to the violation.
(3) Even though the team at bat elects to take the play,
the violation shall be recognized and the penalties in
subsection 1 will still be in effect.
(4) If the manager of the team at bat does not elect to
accept the play, the umpire-in-chief shall call an auto-
matic ball and, if there are any runners on base, a balk.
(5) The umpire shall be sole judge on whether any por-
tion of this rule has been violated.
Rule 6.02(d)(1) through 6.02(d)(5) Comment: If a pitcher vio-
lates either Rule 6.02(c)(2) or Rule 6.02(c)(3) and, in the judg-
ment of the umpire, the pitcher did not intend, by his act, to
alter the characteristics of a pitched ball, then the umpire may,
in his discretion, warn the pitcher in lieu of applying the
penalty set forth for violations of Rules 6.02 (c)(2) through
6.02(c)(6).  If the pitcher persists in violating either of those
Rules, however, the umpire should then apply the penalty.
Rule 6.02(d) Comment: If at any time the ball hits the rosin
bag it is in play. In the case of rain or wet field, the umpire may

instruct the pitcher to carry the rosin bag in his hip pocket. A
pitcher may use the rosin bag for the purpose of applying rosin
to his bare hand or hands.  Neither the pitcher nor any other
player shall dust the ball with the rosin bag; neither shall the
pitcher nor any other player be permitted to apply rosin from
the bag to his glove or dust any part of his uniform with the
rosin bag.
6.03 Batter Illegal Action
(a) A batter is out for illegal action when:
(1) He hits a ball with one or both feet on the ground entirely
outside the batter's box.
Rule 6.03(a)(1) Comment: If a batter hits a ball fair or foul
while out of the batter's box, he shall be called out.  Umpires
should pay particular attention to the position of the batter's
feet if he attempts to hit the ball while he is being intentionally
passed.  A batter cannot jump or step out of the batter's box
and hit the ball.
(2) He steps from one batter's box to the other while the
pitcher is in position ready to pitch;
(3) He interferes with the catcher's fielding or throwing by
stepping out of the batter's box or making any other
movement that hinders the catcher's play at home base.
(4) He throws his bat into fair or foul territory and hits a
catcher (including the catcher's glove) and the catcher
was attempting to catch a pitch with a runner(s) on base
and/or the pitch was a third strike.
EXCEPTION to Rules 6.03(a)(3) and (4):  Batter is not out if
any runner attempting to advance is put out, or if runner trying
to score is called out for batter's interference.
Rules 6.03(a )(3) and (4) Comment: If the batter interferes
with the catcher, the plate umpire shall call "interference."  The
batter is out and the ball dead.  No player may advance on such
interference (offensive interference) and all runners must
return to the last base that was, in the judgment of the umpire,

legally touched at the time of the interference.
If, however, the catcher makes a play and the runner attempting
to advance is put out, it is to be assumed there was no actual
interference and that runner is outnot the batter.  Any other
runners on the base at the time may advance as the ruling is
that there is no actual interference if a runner is retired.  In that
case play proceeds just as if no violation had been called.
If a batter strikes at a ball and misses and swings so hard he
carries the bat all the way around and, in the umpire's judg-
ment, unintentionally hits the catcher or the ball in back of him
on the backswing, it shall be called a strike only (not interfer-
ence).  The ball will be dead, however, and no runner shall
advance on the play.
(5) He uses or attempts to use a bat that, in the umpire's
judgment, has been altered or tampered with in such a
way to improve the distance factor or cause an unusual
reaction on the baseball. This includes bats that are filled,
flat-surfaced, nailed, hollowed, grooved or covered with
a substance such as paraffin, wax, etc.
(1) No advancement on the bases will be allowed (except
advancements that are not caused by the use of an illegal
bat, e,g., stolen base, balk, wild pitch, passed ball), and
any out or outs made during a play shall stand.  In addi-
tion to being called out, the player shall be ejected from
the game and may be subject to additional penalties as
determined by his League President.
Rule 6.03(a)(5) Comment: A batter shall be deemed to have
used or attempted to use an illegal bat if he brings such a bat
into the batter's box.
(b) Batting Out of Turn
(1) A batter shall be called out, on appeal, when he fails to
bat in his proper turn, and another batter completes a time
at bat in his place.
(2) The proper batter may take his place in the batter's box at
any time before the improper batter becomes a runner or

is put out, and any balls and strikes shall be counted in
the proper batter's time at bat.
(3) When an improper batter becomes a runner or is put
out, and the defensive team appeals to the umpire before
the first pitch to the next batter of either team, or before
any play or attempted play, the umpire shall (1) declare
the proper batter out; and (2) nullify any advance or
score made because of a ball batted by the improper bat-
ter or because of the improper batter's advance to first
base on a hit, an error, a base on balls, a hit batter or
otherwise.
(4) If a runner advances, while the improper batter is at bat,
on a stolen base, balk, wild pitch or passed ball, such
advance is legal.
(5) When an improper batter becomes a runner or is put out,
and a pitch is made to the next batter of either team
before an appeal is made, the improper batter thereby
becomes the proper batter, and the results of his time at
bat become legal.
(6) When the proper batter is called out because he has failed
to bat in turn, the next batter shall be the batter whose
name follows that of the proper batter thus called out.
(7) When an improper batter becomes a proper batter
because no appeal is made before the next pitch, the next
batter shall be the batter whose name follows that of such
legalized improper batter.  The instant an improper bat-
ter's actions are legalized, the batting order picks up with
the name following that of the legalized improper batter.
Rule 6.03 (b )(7) Comment: The umpire shall not direct the
attention of any person to the presence in the batter's box of an
improper batter. This rule is designed to require constant vigi-
lance by the players and managers of both teams.
There are two fundamentals to keep in mind: When a player
bats out of turn, the proper batter is the player called out. If
an improper batter bats and reaches base or is out and no

appeal is made before a pitch to the next batter, or before any
play or attempted play, that improper batter is considered to
have batted in proper turn and establishes the order that is to
follow.
APPROVED RULING: To illustrate various situations arising
from batting out of turn, assume a first-inning batting order as
follows:
Abel-Baker-Charles-Daniel-Edward-Frank-George-
Hooker-Irwin.
PLAY (1)  Baker bats. With the count 2 balls and 1 strike,
(a) the offensive team discovers the error or (b) the defen-
sive team appeals. RulingIn either case, Abel replaces
Baker, with the count on him 2 balls and 1 strike.
PLAY (2)  Baker bats and doubles. The defensive team
appeals (a) immediately or (b) after a pitch to Charles.
RULING: (a) Abel is called out and Baker is the proper batter;
(b) Baker stays on second and Charles is the proper batter.
PLAY (3)  Abel walks. Baker walks. Charles forces Baker.
Edward bats in Daniel's turn. While Edward is at bat, Abel
scores and Charles goes to second on a wild pitch. Edward
grounds out, sending Charles to third. The defensive team
appeals (a) immediately or (b) after a pitch to Daniel.
RULING: (a) Abel's run counts and Charles is entitled to
second base since these advances were not made because of
the improper batter batting a ball or advancing to first base.
Charles must return to second base because his advance to
third resulted from the improper batter batting a ball. Daniel
is called out, and Edward is the proper batter; (b) Abel's run
counts and Charles stays on third. The proper batter is
Frank.
PLAY (4) With the bases full and two out. Hooker bats in
Frank's turn, and triples, scoring three runs. The defensive
team appeals (a) immediately, or (b) after a pitch to George.
RULING: (a) Frank is called out and no runs score. George

is the proper batter to lead off the second inning; (b) Hooker
stays on third and three runs score. Irwin is the proper bat-
ter.
PLAY (5) After Play (4)(b) above, George continues at
bat.  (a) Hooker is picked off third base for the third out, or
(b) George flies out, and no appeal is made.  Who is the
proper leadoff batter in the second inning?
RULING: (a) Irwin. He became the proper batter as soon as
the first pitch to George legalized Hooker's triple; (b)
Hooker.  When no appeal was made, the first pitch to the
leadoff batter of the opposing team legalized George's time
at bat.
PLAY (6 ) Daniel walks and Abel comes to bat. Daniel
was an improper batter, and if an appeal is made before the
first pitch to Abel, Abel is out, Daniel is removed from base,
and Baker is the proper batter. There is no appeal, and a
pitch is made to Abel.  Daniel's walk is now legalized, and
Edward thereby becomes the proper batter.  Edward can
replace Abel at any time before Abel is put out or becomes a
runner.  He does not do so. Abel flies out, and Baker comes
to bat.  Abel was an improper batter, and if an appeal is
made before the first pitch to Baker, Edward is out, and the
proper batter is Frank.  There is no appeal, and a pitch is
made to Baker. Abel's out is now legalized, and the proper
batter is Baker. Baker walks.  Charles is the proper batter.
Charles flies out.  Now Daniel is the proper batter, but he is
on second base.  Who is the proper batter?
RULING: The proper batter is Edward.  When the proper
batter is on base, he is passed over, and the following batter
becomes the proper batter.
6.04 Unsportsmanlike Conduct
(a) No manager, player, substitute, coach, trainer or batboy shall at
any time, whether from the bench, the coach's box or on the
playing field, or elsewhere:
(1) Incite, or try to incite, by word or sign a demonstration by
spectators;

(2) Use language which will in any manner refer to or reflect
upon opposing players, an umpire, or any spectator;
(3) Call "Time," or employ any other word or phrase or com-
mit any act while the ball is alive and in play for the obvi-
ous purpose of trying to make the pitcher commit a balk.
(4) Make intentional contact with the umpire in any manner.
(b) Players in uniform shall not address or mingle with spectator,
nor sit in the stands before, during, or after a game. No man-
ager, coach or player shall address any spectator before or dur-
ing a game. Players of opposing teams shall not fraternize at
any time while in uniform.
(c) No fielder shall take a position in the batter's line of vision, and
with deliberate unsportsmanlike intent, act in a manner to dis-
tract the batter.
PENALTY: The offender shall be removed from the game and
shall leave the playing field, and, if a balk is made, it shall be
nullified.
(d) (4.07) When a manager, player, coach or trainer is ejected from
a game, he shall leave the field immediately and take no further
part in that game. He shall remain in the club house or change
to street clothes and either leave the park or take a seat in the
grandstand well removed from the vicinity of his team's bench
or bullpen.
Rule 6.04(d) Comment: If a manager, coach or player is under
suspension he may not be in the dugout or press box during the
course of a game.
(e) (4.08) When the occupants of a player's bench show violent
disapproval of an umpire's decision, the umpire shall first give
warning that such disapproval shall cease.
PENALTY: [If such action continues] The umpire shall order
the offenders from the bench to the club house.  If he is unable
to detect the offender, or offenders, he may clear the bench of
all substitute players. The manager of the offending team shall
have the privilege of recalling to the playing field only those
players needed for substitution in the game.

7.00ENDING THE GAME
7.01 Regulation Games
(a) A regulation game consists of nine innings, unless extended
because of a tie score, or shortened (1) because the home team
needs none of its half of the ninth inning or only a fraction of it,
or (2) because the umpire-in-chief calls the game.
EXCEPTION: National Association leagues may adopt
a rule providing that one or both games of a double-
header shall be seven innings in length. In such games,
any of these rules applying to the ninth inning shall
apply to the seventh inning.
(b) If the score is tied after nine completed innings play shall con-
tinue until (1) the visiting team has scored more total runs
than the home team at the end of a completed inning, or (2)
the home team scores the winning run in an uncompleted
inning.
(c) If a game is called, it is a regulation game:
(1) If five innings have been completed;
(2) If the home team has scored more runs in four or four
and a fraction half-innings than the visiting team has
scored in five completed half-innings;
(3) If the home team scores one or more runs in its half of
the fifth inning to tie the score.
(d) If a regulation game is called with the score tied, it shall
become a suspended game.  See Rule 7.02.
(e) If a game is postponed or otherwise called before it has become
a regulation game, the umpire-in-chief shall declare it "No
Game," unless the game is called pursuant to Rules 7.02(a)(3)
or 7.02(a)(4), which shall be a suspended game at any time
after it starts.
(f ) A League President may determine whether rain checks will be
honored for any regulation or suspended game that has pro-
gressed to or beyond a point of play described in Rule 7.01(c).

Rule 7.01 Comment: The Major Leagues have determined that
Rules 7.01(c) and 7.01(e) do not apply to any Wild Card,
Division Series, League Champion ship Series or World Series
games or for any additional Major League championship sea-
son game played to break a tie.
(g) The score of a regulation game is the total number of runs
scored by each team at the moment the game ends.
(1) The game ends when the visiting team completes its
half of the ninth inning if the home team is ahead.
(2) The game ends when the ninth inning is completed, if
the visiting team is ahead.
(3) If the home team scores the winning run in its half of the
ninth inning (or its half of an extra inning after a tie), the
game ends immediately when the winning run is scored.
EXCEPTION: If the last batter in a game hits a home
run out of the playing field, the batter-runner and all
runners on base are permitted to score, in accordance
with the base-running rules, and the game ends when
the batter-runner touches home plate.
APPROVED RULING: The batter hits a home run out
of the playing field to win the game in the last half of
the ninth or an extra inning, but is called out for pass-
ing a preceding runner. The game ends immediately
when the winning run is scored, unless there are two
out and the winning run has not yet reached home
plate when the runner passes another, in which case
the inning is over and only those runs that scored
before the runner passes another shall count.
(4) A called game ends at the moment the umpire termi-
nates play, unless it becomes a suspended game pur-
suant to Rule 7.02(a).
7.02 Suspended, Postponed, and Tie Games
(a) A game shall become a suspended game that must be com-
pleted at a future date if the game is terminated for any of the
following reasons:

retractable roof, a tarpaulin, or other water removal
equipment);
(4) Darkness, when a law prevents the lights from being
turned on;
(5) Weather, if a regulation game is called while an inning
is in progress and before the inning is completed, and
the visiting team has scored one or more runs to take
the lead, and the home team has not retaken the lead;
or
(6) It is a regulation game that is called with the score tied;
National Association Leagues may also adopt the following
rules for suspended games. (If adopted by a National
Association League, Rule 7.01(e) would not apply to their
games.);
(7) The game has not become a regulation game (4
innings with the home team ahead, or 5 innings with the
visiting club ahead or tied);
(8) If a game is suspended before it becomes a regulation
game, and is continued prior to another regularly sched-
uled game, the regularly scheduled game shall be seven
innings in length. See the exception described in Rule
7.01(a);
(9) If a game is suspended after it is a regulation game, and
is continued prior to another regularly scheduled game,
the regularly scheduled game shall be a nine-inning
game.
EXCEPTION: Optional Rules 7.02(a)(7), 7.02(a)(8),
and 7.02(a)(9) for National Association Leagues shall not
apply to the last scheduled game between the two teams
during the championship season.  A National Association

League may adopt any of Rules 7.02(a)(7), 7.02(a)(8),
and 7.02(a)(9) for its post-season games.
No game called because of a curfew (Rule 7.02(a)(1),
weather (Rule 7.02(a)(5), a time limit (Rule 7.02(a)(2), or
with a tied score (Rule 7.02(a)(6) shall be a suspended
game unless it has progressed far enough to have been a
regulation game pursuant to Rule 7.01(c).  A game called
pursuant to Rules 7.02(a)(3) or 7.02(a)(4) shall be a sus-
pended game at any time after it starts.
NOTE:  Weather and similar conditionsRules 7.02(a)(1)
through 7.02(a)(5)shall take precedence in determining
whether a called game shall be a suspended game.  If a
game is halted by weather, and subsequent light failure or
an intervening curfew or time limit prevents its resumption,
the game shall not be a suspended game.  If a game is
halted by light failure, and weather or field conditions pre-
vent its resumption, the game shall not be a suspended
game.  A game can only be considered a suspended game if
stopped for any of the six reasons specified in Rule 7.02(a).
Rule 7.02(a ) Comment: The Major Leagues have determined
that Rule 7.02(a) does not apply to any Wild Card, Division
Series, League Championship Series or World Series games or
for any additional Major League championship season game
played to break a tie.
(b) A suspended game shall be resumed and completed as follows:
(1) Immediately preceding the next scheduled single game
between the two clubs on the same grounds; or
(2) Immediately preceding the next scheduled double-
header between the two clubs on the same grounds, if
no single game remains on the schedule; or
(3) If suspended on the last scheduled date between the two
clubs in that city, transferred and played on the grounds
of the opposing club, if possible;

gle game, or

(4) Any suspended game that has progressed far enough to
become a regulation game, but which has not been com-
pleted prior to the last scheduled game between the two
teams during the championship season shall become a
called game, as follows:
(A) If one team is ahead, the team that is ahead shall
be declared the winner (unless the game is
called while an inning is in progress and before
the inning is completed, and the visiting team
has scored one or more runs to take the lead, and
the home team has not retaken the lead, in which
case the score upon the completion of the last
full inning shall stand for purposes of this Rule
7.02(b)(4); or
(B) If the score is tied, the game shall be declared a
"tie game" (unless the game is called while an
inning is in progress and before the inning is
completed, and the visiting team has scored one
or more runs to tie the game, and the home team
has not retied the game, in which case the score
upon the completion of the last full inning shall
stand for purposes of this Rule 7.02(b)(4).
(5) Any postponed game, suspended game (that has not pro-
gressed far enough to become a regulation game), or tie
game that has not been rescheduled and completed prior
to the last scheduled game between the two teams dur-
ing the championship season must be played (or contin-
ued, in the case of a suspended or tie game) to a com-
pleted regulation game, if the League President deter-
mines that not playing such game might affect eligibility
for the post-season and/or home-field advantage for any
Wild Card or Division Series game.

Series, League Championship Series or World Series games or
for any additional Major League championship season game
played to break a tie.
The National Association has determined that games shall not
be rescheduled and played to a completed regulation game in
accordance with Rule 7.02(b)(5) for the purpose of determining
eligibility or home-field advantage for the post-season.
If a suspended game is to resume and no single game remains
on the schedule, the National Association has determined that
only a single game will be played after completing the sus-
pended game.
(c) A suspended game shall be resumed at the exact point of
suspension of the original game.  The completion of a sus-
pended game is a continuation of the original game.  The
lineup and batting order of both teams shall be exactly the
same as the lineup and batting order at the moment of sus-
pension, subject to the rules governing substitution. Any
player may be replaced by a player who had not been in the
game prior to the suspension.  No player removed before the
suspension may be returned to the lineup.
(a) A player who was not with the club when the game was sus-
pended may be used as a substitute, even if he has taken the
place of a player no longer with the club who would not
have been eligible because he had been removed from the
lineup before the game was suspended.
Rule 7.02(c) Comment:  If immediately prior to the call of a
suspended game, a substitute pitcher has been announced but
has not retired the side or pitched until the batter becomes a
base runner, such pitcher, when the suspended game is later
resumed may, but is not required to start the resumed portion of
the game. However, if he does not start he will be considered as
having been substituted for and may not be used in that game.
7.03 Forfeited Games
(a) A game may be forfeited to the opposing team when a team:
(1) Fails to appear upon the field, or being upon the field,
refuses to start play within five minutes after the
umpire-in-chief has called "Play" at the appointed hour

for beginning the game, unless such delayed appearance
is, in the umpire-in-chief's judgment, unavoidable;
(2) Employs tactics palpably designed to delay or shorten
the game;
(3) Refuses to continue play during a game unless the game
has been suspended or terminated by the umpire-in-
chief;
(4) Fails to resume play, after a suspension, within one
minute after the umpire-in-chief has called "Play;"
(5) After warning by the umpire, willfully and persistently
violates any rules of the game;
(6) Fails to obey within a reasonable time the umpire's
order for removal of a player from the game;
(7) Fails to appear for the second game of a doubleheader
within twenty minutes after the close of the first game
unless the umpire-in-chief of the first game shall have
extended the time of the intermission.
(b) A game shall be forfeited to the opposing team when a team is
unable or refuses to place nine players on the field.
(c) A game shall be forfeited to the visiting team if, after it has
been suspended, the order of the umpire to groundskeepers
respecting preparation of the field for resumption of play inten-
tionally or willfully is not complied with.
(d) If the umpire-in-chief declares a game forfeited he shall trans-
mit a written report to the League President within 24 hours
thereafter, but failure of such transmittal shall not affect the for-
feiture.
7.04 Protesting Games
Each league shall adopt rules governing procedure for protesting a
game, when a manager claims that an umpire's decision is in viola-
tion of these rules. No protest shall ever be permitted on judgment
decisions by the umpire. In all protested games, the decision of the
League President shall be final.

Even if it is held that the protested decision violated the rules, no
replay of the game will be ordered unless in the opinion of the
League President the violation adversely affected the protesting
team's chances of winning the game.
Rule 7.04 Comment: Whenever a manager protests a game
because of alleged misapplication of the rules the protest will
not be recognized unless the umpires are notified at the time
the play under protest occurs and before the next pitch, play or
attempted play. A protest arising on a game-ending play may
be filed until 12 noon the following day with the league office.

8.00THE UMPIRE
8.01 Umpire Qualifications and Authority
(a) The League President shall appoint one or more umpires to
officiate at each league championship game.  The umpires shall
be responsible for the conduct of the game in accordance with
these official rules and for maintaining discipline and order on
the playing field during the game.
(b) Each umpire is the representative of the league and of profes-
sional baseball, and is authorized and required to enforce all of
these rules.  Each umpire has authority to order a player, coach,
manager or club officer or employee to do or refrain from
doing anything which affects the administering of these rules,
and to enforce the prescribed penalties.
(c) Each umpire has authority to rule on any point not specifically
covered in these rules.
(d) Each umpire has authority to disqualify any player, coach,
manager or substitute for objecting to decisions or for unsports-
manlike conduct or language, and to eject such disqualified
person from the playing field. If an umpire disqualifies a player
while a play is in progress, the disqualification shall not take
effect until no further action is possible in that play.
(e) Each umpire has authority at his discretion to eject from the
playing field (1) any person whose duties permit his presence on
the field, such as ground crew members, ushers, photographers,
newsmen, broadcasting crew members, etc., and (2) any specta-
tor or other person not authorized to be on the playing field.
8.02 Appeal of Umpire Decisions
(a) Any umpire's decision which involves judgment, such as, but
not limited to, whether a batted ball is fair or foul, whether a
pitch is a strike or a ball, or whether a runner is safe or out, is
final. No player, manager, coach or substitute shall object to
any such judgment decisions.

Rule 8.02(a) Comment: Players leav ing their position in the
field or on base, or managers or coaches leaving the bench or
coaches box, to argue on BALLS AND STRIKES will not be
permitted.  They should be warned if they start for the plate to
protest the call.  If they continue, they will be ejected from the
game.
(b) If there is reasonable doubt that any umpire's decision may be
in conflict with the rules, the manager may appeal the decision
and ask that a correct ruling be made. Such appeal shall be
made only to the umpire who made the protested decision.
(c) If a decision is appealed, the umpire making the decision may
ask another umpire for information before making a final deci-
sion. No umpire shall criticize, seek to reverse or interfere with
another umpire's decision unless asked to do so by the umpire
making it. If the umpires consult after a play and change a call
that had been made, then they have the authority to take all
steps that they may deem necessary, in their discretion, to elim-
inate the results and consequences of the earlier call that they
are reversing, including placing runners where they think those
runners would have been after the play, had the ultimate call
been made as the initial call, disregarding interference or
obstruction that may have occurred on the play; failures of run-
ners to tag up based upon the initial call on the field; runners
passing other runners or missing bases; etc., all in the discre-
tion of the umpires. No player, manager or coach shall be per-
mitted to argue the exercise of the umpires' discretion in
resolving the play and any person so arguing shall be subject to
ejection.  Notwithstanding the foregoing, correction of a
missed ball-strike count shall not be permitted after a pitch is
thrown to a subsequent batter, or in the case of the final batter
of an inning or game, after all infielders of the defensive team
leave fair territory.
Rule 8.02(c) Comment: A manager is permitted to ask the
umpires for an explanation of the play and how the umpires
have exercised their discretion to eliminate the results and con-
sequences of the earlier call that the umpires are reversing.
Once the umpires explain the result of the play, however, no

one is permitted to argue that the umpires should have exer-
cised their discretion in a different manner.
The manager or the catcher may request the plate umpire to ask
his partner for help on a half swing when the plate umpire calls
the pitch a ball, but not when the pitch is called a strike. The
manager may not complain that the umpire made an improper
call, but only that he did not ask his partner for help. Field
umpires must be alerted to the request from the plate umpire
and quickly respond. Managers may not protest the call of a
ball or strike on the pretense they are asking for information
about a half swing.
Appeals on a half swing may be made only on the call of ball
and when asked to appeal, the home plate umpire must refer to
a base umpire for his judgment on the half swing. Should the
base umpire call the pitch a strike, the strike call shall prevail.
Appeals on a half swing must be made before the next pitch, or
any play or attempted play. If the half swing occurs during a
play which ends a half-inning, the appeal must be made before
all infielders of the defensive team leave fair territory.
Baserunners must be alert to the possibility that the base
umpire on appeal from the plate umpire may reverse the call of
a ball to the call of a strike, in which event the runner is in
jeopardy of being out by the catcher's throw. Also, a catcher
must be alert in a base stealing situation if a ball call is
reversed to a strike by the base umpire upon appeal from the
plate umpire.
The ball is in play on appeal on a half swing.
On a half swing, if the manager comes out to argue with first or
third base umpire and if after being warned he persists in argu-
ing, he can be ejected as he is now arguing over a called ball or
strike.
(d) No umpire may be replaced during a game unless he is injured
or becomes ill.
(d) If there is only one umpire, he shall have complete jurisdiction
in administering the rules.  He may take any position on the
playing field which will enable him to discharge his duties

(usually behind the catcher, but sometimes behind the pitcher
if there are runners).  He shall be considered umpire-in-chief.
(e) If there are two or more umpires, one shall be designated
umpire-in-chief and the others field umpires.
8.03 Umpire Position
(a) The umpire-in-chief shall stand behind the catcher. (He usually
is called the plate umpire.) His duties shall be to:
(1) Take full charge of, and be responsible for, the proper
conduct of the game;
(2) Call and count balls and strikes;
(3) Call and declare fair balls and fouls except those com-
monly called by field umpires;
(4) Make all decisions on the batter;
(5) Make all decisions except those commonly reserved for
the field umpires;
(6) Decide when a game shall be forfeited;
(7) If a time limit has been set, announce the fact and the
time set before the game starts;
(8) Inform the official scorer of the official batting order,
and any changes in the lineups and batting order, on
request;
(9) Announce any special ground rules, at his discretion.
(b) A field umpire may take any position on the playing field he
thinks best suited to make impending decisions on the bases.
His duties shall be to:
(1) Make all decisions on the bases except those specifi-
cally reserved to the umpire-in-chief;
(2) Take concurrent jurisdiction with the umpire-in-chief in
calling "Time," balks, illegal pitches, or defacement or
discoloration of the ball by any player.
(3) Aid the umpire-in-chief in every manner in enforcing
the rules, and excepting the power to forfeit the game,

shall have equal authority with the umpire-in-chief in
administering and enforcing the rules and maintaining
discipline.
(c) If different decisions should be made on one play by different
umpires, the umpire-in-chief shall call all the umpires into con-
sultation, with no manager or player present. After consulta-
tion, the umpire-in-chief (unless another umpire may have been
designated by the League President) shall determine which
decision shall prevail, based on which umpire was in best posi-
tion and which decision was most likely correct.  Play shall
proceed as if only the final decision had been made.
8.04 Reporting
(a) The umpire shall report to the League President within twelve
hours after the end of a game all violations of rules and other
incidents worthy of comment, including the disqualification of
any trainer, manager, coach or player, and the reasons therefor.
(b) When any trainer, manager, coach or player is disqualified for a
flagrant offense such as the use of obscene or indecent lan-
guage, or an assault upon an umpire, trainer, manager, coach or
player, the umpire shall forward full particulars to the League
President within four hours after the end of the game.
(c) After receiving the umpire's report that a trainer, manager,
coach or player has been disqualified, the League President
shall impose such penalty as he deems justified, and shall
notify the person penalized and the manager of the club of
which the penalized person is a member.  If the penalty in -
cludes a fine, the penalized person shall pay the amount of the
fine to the league within five days after receiving notice of the
fine.  Failure to pay such fine within five days shall result in the
offender being debarred from participation in any game and
from sitting on the players' bench during any game, until the
fine is paid.

GENERAL INSTRUCTIONS TO UMPIRES
Umpires, on the field, should not indulge in conversation with play-
ers. Keep out of the coaching box and do not talk to the coach on duty.
Keep your uniform in good condition. Be active and alert on the
field.
Be courteous, always, to club officials; avoid visiting in club
offices and thoughtless familiarity with officers or employees of contest-
ing clubs.
When you enter a ball park your sole duty is to umpire a ball game
as the representative of baseball.
Do not allow criticism to keep you from studying out bad situations
that may lead to protested games.  Carry your rule book.  It is better to
consult the rules and hold up the game ten minutes to decide a knotty
problem than to have a game thrown out on protest and replayed.
Keep the game moving.  A ball game is often helped by energetic
and earnest work of the umpires.
You are the only official representative of baseball on the ball field.
It is often a trying position which requires the exercise of much patience
and good judgment, but do not forget that the first essential in working
out of a bad situation is to keep your own temper and self-control.
You no doubt are going to make mistakes, but never attempt to
"even up" after having made one.  Make all decisions as you see them
and forget which is the home or visiting club.
Keep your eye everlastingly on the ball while it is in play. It is more
vital to know just where a fly ball fell, or a thrown ball finished up, than
whether or not a runner missed a base.  Do not call the plays too quickly,
or turn away too fast when a fielder is throwing to complete a double
play. Watch out for dropped balls after you have called a man out.
Do not come running with your arm up or down, denoting "out" or
"safe."  Wait until the play is completed before making any arm motion.
Each umpire team should work out a simple set of signals, so the
proper umpire can always right a manifestly wrong decision when con-
vinced he has made an error. If sure you got the play correctly, do not be
stampeded by players' appeals to "ask the other man." If not sure, ask

one of your associates. Do not carry this to extremes, be alert and get
your own plays.  But remember!  The first requisite is to get decisions
correctly.  If in doubt don't hesitate to consult your associate.  Umpire
dignity is important but never as important as "being right."
Most important rule for umpires is always "BE IN POSITION TO
SEE EVERY PLAY."  Even though your decision may be 100% right,
players still question it if they feel you were not in a spot to see the play
clearly and definitely.
Finally, be courteous, impartial and firm, and so compel respect
from all.

an error. The official scorer shall communicate such decisions
to the press box and broadcasting booths by hand signals or
over the press box loudspeaker system and shall advise the
public address announcer of such decisions, if requested. Club
officials and players are prohibited from communicating with

the official scorer regarding any such decisions.
(a) The official scorer shall make all decisions concerning judg-
ment calls within 24 hours after a game concludes or is sus-
pended. A Major League player or club may request that the
Executive Vice President for Baseball Operations review a
judgment call of an official scorer made in a game in which
such player or club participated, by notifying the Office of the
Commissioner in writing or by approved electronic means
within 72 hours of the conclusion or suspension of such game,
or within 72 hours of the official scorer's call, in the event the
official scorer changes a call within 24 hours after a game con-
cludes or is suspended, as provided in this Rule 9.01(a).  The
Executive Vice President for Baseball Operations shall have
access to all relevant and available video and, after considering
any evidence he wishes to consider, may order a change in a
judgment call if he determines that the judgment of the official
scorer was clearly erroneous. No judgment decision shall be
changed thereafter. If the Executive Vice President for Baseball
Operations determines that a player or club has abused the
appeals process by repeatedly filing frivolous appeals, or acting
in bad faith, he may, after providing a warning, impose reason-
able sanctions on the club or player. A Minor League player or
club may request that the League President review a judgment
call of an official scorer in accordance with league rules.
(a) After each game, including forfeited and called games, the offi-
cial scorer shall prepare a report, on a form prescribed by the
Office of the Commissioner, with respect to Major League
games, and the Minor League President, with respect to Minor
League games, listing the date of the game, where it was
played, the names of the competing clubs and the umpires, the
full score of the game and all records of individual players
compiled according to the system specified in this Rule 9. The
official scorer shall forward this report to the Office of the
Commissioner, with respect to Major League games, and the
league office, with respect to Minor League games, as soon as
practicable after the game ends. The official scorer shall for-
ward the report of any suspended game as soon as practicable
after the game has been completed, or after it becomes a called

game because it cannot be completed, as provided by the Rule
7.02)  Rule 4.12(b)(4)).
Rule 9.01(a) Comment:  The official scorer shall forward the
official score report to the league statistician instead of to the
league office, if requested to do so by the league. In the event
of any discrepancy in records maintained by a league statisti-
cian and the rulings by an official scorer, the report of such offi-
cial scorer shall control. League statisticians and official scor-
ers should consult cooperatively to resolve any discrepancies.
(b) (1) In all cases, the official scorer shall not make a scoring
decision that is in conflict with Rule 9 or any other Official
Baseball Rule. The official scorer shall conform strictly to the
rules of scoring set forth in this Rule 9.  The official scorer
shall not make any decision that conflicts with an umpire's
decision. The official scorer shall have authority to rule on any
point not specifically covered in these rules. The Office of the
Commissioner, with respect to Major League scorers, and the
League President, with respect to Minor League scorers shall
order changed any decision of an official scorer that contra-
dicts the rules of scoring set forth in this Rule 9 and shall take
whatever remedial actions as may be necessary to correct any
statistics that need correction as a result of such mistaken scor-
ing decision.
(b) (2) If the teams change sides before three men are put out, the
official scorer shall immediately inform the umpire-in-
chief of the mistake.
(b) (3) If the game is protested or suspended, the official scorer
shall make a note of the exact situation at the time of the
protest or suspension, including the score, the number of
outs, the position of any runners, the ball-and-strike count
on the batter, the lineups of both teams and the players who
have been removed from the game for each team.
Rule 9.01(b)(3) Comment:  It is important that a suspended
game resume with exactly the same situation as existed at the
time of suspension.  If a protested game is ordered replayed
from the point of protest, the game must be resumed with
exactly the situation that existed just before the protested play.

the respect and dignity of his office and shall be accorded full
protection by the Office of the Commissioner, with respect to
Major League scorers, and the League President, with respect

appropriate league official any indignity expressed by any man-
ager, player, club employee or club officer in the course of, or
as the result of, the discharge of official scorer duties.

sixth inning, the official scorer shall credit that pitcher with 5
innings. If a starting pitcher is replaced with none out in the
sixth inning, the official scorer shall credit that pitcher with 5
innings and make the notation that that pitcher faced _____
batters in the sixth, noting the number of batters faced. If a
relief pitcher retires two batters and is replaced, the official
scorer shall credit that pitcher with  of an inning pitched. If a

(g) Number of runners left on base by each team. This total shall
include all runners who get on base by any means and who do

this total a batter-runner whose batted ball results in another
runner being retired for the third out.
(h) Names of batters who hit home runs with the bases full.
( i) Number of outs when winning run scored, if the game was won
in the last half-inning.

(a) In compiling the official score report, the official scorer shall
list each player's name and fielding position, or positions, in
the order in which the player batted, or would have batted if the
game ended before the player came to bat.
Rule 9.03(a) Comment: When a player does not exchange posi-
tions with another fielder but is merely placed in a different spot
for a particular batter (for example, if a second baseman goes to
the outfield to form a four-man outfield, or if a third baseman
moves to a position between the shortstop and second base-
man), the official scorer should not list this as a new position.
(b) The official scorer shall identify in the official score report any
player who enters the game as a substitute batter or substitute
runner, whether or not such player continues in the game there-

after, in the batting order by a special symbol that shall refer to
a separate record of substitute batters and runners. The record
of substitute batters shall describe what the substitute batter
did. The record of substitute batters and runners shall include
the name of any such substitute whose name is announced, but
who is removed for another substitute before he actually gets
into the game. Any such second substitute shall be recorded as
batting or running for the first announced substitute.
Rule 9.03(b) Comment:  Lower case letters are recommended
as symbols for substitute batters and numerals are recom-
mended as symbols for substitute runners. For example, an
official score report may note as follows: "a-Singled for Abel
in third inning; b-Flied out for Baker in sixth inning; c-Hit into
force for Charles in seventh inning; d-Grounded out for Daniel
in ninth inning; 1-Ran for Edward in ninth inning." If a substi-
tute's name is announced but the substitute is removed for
another substitute before he actually gets into the game, the
official scorer report shall record the substitute, for example, as
follows: "e-Announced as substitute for Frank in seventh
inning."
(c) How to Prove a Box Score
(c) A box score shall balance (or is proven) when the total of the
team's times at bat, bases on balls received, hit batters, sacrifice
bunts, sacrifice flies and batters awarded first base because of
interference or obstruction equals the total of that team's runs,
players left on base and the opposing team's putouts.
(d) When Player Bats Out of Turn
(d) When a player bats out of turn and is put out, and the proper
batter is called out before the ball is pitched to the next batter,
the official scorer shall charge the proper batter with a time at
bat and score the putout and any assists the same as if the cor-
rect batting order had been followed. If an improper batter
becomes a runner and the proper batter is called out for having
missed his turn at bat, the official scorer shall charge the proper
batter with a time at bat, credit the putout to the catcher and
ignore everything entering into the improper batter's safe

arrival on base. If more than one batter bats out of turn in suc-
cession, the official scorer shall score all plays just as they
occur, skipping the turn at bat of the player or players who first
missed batting in the proper order.
(e) Called and Forfeited Games
(1) If a regulation game is called, the official scorer shall
include the record of all individual and team actions up
to the moment the game ends, as defined in Rule 7.01.
If the game is a tie game, the official scorer shall not
enter a winning or losing pitcher.
(2) If a regulation game is forfeited, the official scorer shall
include the record of all individual and team actions up to
the time of forfeit. If the winning team by forfeit is ahead
at the time of forfeit, the official scorer shall enter as win-
ning and losing pitchers the players who would have
qualified as the winning and losing pitchers if the game
had been called at the time of forfeit. If the winning team
by forfeit is behind or if the score is tied at the time of
forfeit, the official scorer shall not enter a winning or los-
ing pitcher. If a game is forfeited before it becomes a reg-
ulation game, the official scorer shall include no records
and shall report only the fact of the forfeit.
Rule 9.03(e) Comment:  The official scorer shall not consider
that, by rule, the score of a forfeited game is 9 to 0 (see Rule
2.00 (Forfeited Game)), notwithstanding the results on the
field at the point the game is forfeited.
9.04 Runs Batted In
A run batted in is a statistic credited to a batter whose action at bat
causes one or more runs to score, as set forth in this Rule 9.04.
(a) The official scorer shall credit the batter with a run batted in for
every run that scores
(1) unaided by an error and as part of a play begun by the
batter's safe hit (including the batter's home run), sacri-
fice bunt, sacrifice fly, infield out or fielder's choice,
unless Rule 9.04(b) applies;

(2) by reason of the batter becoming a runner with the bases
full (because of a base on balls, an award of first base for
being touched by a pitched ball or for interference or
obstruction); or
(3) when, before two are out, an error is made on a play on
which a runner from third base ordinarily would score.
(b) The official scorer shall not credit a run batted in
(1) when the batter grounds into a force double play or a
reverse-force double play; or
(2) when a fielder is charged with an error because the fielder
muffs a throw at first base that would have completed a
force double play.
(c) The official scorer's judgment must determine whether a run
batted in shall be credited for a run that scores when a fielder
holds the ball or throws to a wrong base.  Ordinarily, if the run-
ner keeps going, the official scorer should credit a run batted
in; if the runner stops and takes off again when the runner
notices the misplay, the official scorer should credit the run as
scored on a fielder's choice.
9.05 Base Hits
A base hit is a statistic credited to a batter when such batter reaches
base safely, as set forth in this Rule 9.05.
(a) The official scorer shall credit a batter with a base hit when:
(1) the batter reaches first base (or any succeeding base)
safely on a fair ball that settles on the ground, that
touches a fence before being touched by a fielder or that
clears a fence;
(2) the batter reaches first base safely on a fair ball hit with
such force, or so slowly, that any fielder attempting to
make a play with the ball has no opportunity to do so;
Rule 9.05(a)(2) Comment:  The official scorer shall credit a hit
if the fielder attempting to handle the ball cannot make a play,
even if such fielder deflects the ball from or cuts off another
fielder who could have put out a runner.

(3) the batter reaches first base safely on a fair ball that takes
an unnatural bounce so that a fielder cannot handle it with
ordinary effort, or that touches the pitcher's plate or any
base (including home plate) before being touched by a
fielder and bounces so that a fielder cannot handle the
ball with ordinary effort;
(4) the batter reaches first base safely on a fair ball that has
not been touched by a fielder and that is in fair territory
when the ball reaches the outfield, unless in the scorer's
judgment the ball could have been handled with ordinary
effort;
(5) a fair ball that has not been touched by a fielder touches a
runner or an umpire, unless a runner is called out for hav-
ing been touched by an Infield Fly, in which case the offi-
cial scorer shall not score a hit; or
(6) a fielder unsuccessfully attempts to put out a preceding
runner and, in the official scorer's judgment, the batter-
runner would not have been put out at first base by ordi-
nary effort.
Rule 9.05(a ) Comment:  In applying Rule 9.05(a), the official
scorer shall always give the batter the benefit of the doubt. A
safe course for the official scorer to follow is to score a hit
when exceptionally good fielding of a ball fails to result in a
putout.
(b) The official scorer shall not credit a base hit when a:
(1) runner is forced out by a batted ball, or would have been
forced out except for a fielding error;
(2) batter apparently hits safely and a runner who is forced to
advance by reason of the batter becoming a runner fails
to touch the first base to which such runner is advancing
and is called out on appeal. The official scorer shall
charge the batter with a time at bat but no hit;
(3) pitcher, the catcher or any infielder handles a batted ball
and puts out a preceding runner who is attempting to
advance one base or to return to his original base, or

would have put out such runner with ordinary effort
except for a fielding error. The official scorer shall charge
the batter with a time at bat but no hit;
(4) fielder fails in an attempt to put out a preceding runner
and, in the scorer's judgment, the batter-runner could
have been put out at first base; or
Rule 9.05(b) Comment:  Rule 9.05(b) shall not apply if the
fielder merely looks toward or feints toward another base
before attempting to make the putout at first base.
(5) is called out for interference with a fielder attempting to
field a batted ball, unless in the scorer's judgment the bat-
ter-runner would have been safe had the interference not
occurred.
9.06 Determining Value of Base Hits
The official scorer shall score a base hit as a one-base hit, two-base
hit, three-base hit or home run when no error or putout results, as
follows:
(a) Subject to the provisions of Rule 9.06(b) and 9.06(c), it is a
one-base hit if the batter stops at first base; it is a two-base hit
if the batter stops at second base; it a three-base hit if the batter
stops at third base; and it is a home run if the batter touches all
bases and scores.
(b) When, with one or more runners on base, the batter advances
more than one base on a safe hit and the defensive team makes
an attempt to put out a preceding runner, the scorer shall deter-
mine whether the batter made a legitimate two-base hit or
three-base hit, or whether the batter-runner advanced beyond
first base on the fielder's choice.
Rule 9.06 Comment:  The official scorer shall not credit the
batter with a three-base hit when a preceding runner is put out
at home plate, or would have been out but for an error. The
official scorer shall not credit the batter with a two-base hit
when a preceding runner trying to advance from first base is
put out at third base, or would have been out but for an error.

The official scorer shall not, however, with the exception of the
above, determine the value of base-hits by the number of bases
advanced by a preceding runner. A batter may deserve a two-
base hit even though a preceding runner advances one or no
bases; a batter may deserve only a one-base hit even though he
reaches second base and a preceding runner advances two
bases.  For example:
(1) Runner on first.  Batter hits to right fielder, who
throws to third base in an unsuccessful attempt to put
out runner. Batter takes second base.  The official
scorer shall credit batter with one-base hit.
(2) Runner on second. Batter hits fair fly ball. Runner
holds up to determine if ball is caught and then
advances only to third base, while batter takes second
base. The official scorer shall credit batter with two-
base hit.
(3) Runner on third. Batter hits high, fair fly. Runner takes
a lead, then runs back to tag up, thinking the ball will
be caught. The ball falls safe, but runner cannot score,
although batter has reached second. The official scorer
shall credit batter with a two-base hit.
(c) When the batter attempts to make a two-base hit or a three-base
hit by sliding, he must hold the last base to which he advances.
If a batter-runner overslides and is tagged out before getting
back to the base safely, he shall be credited with only as many
bases as he attained safely. If a batter-runner overslides second
base and is tagged out, the official scorer shall credited him
with a one-base hit; if the batter-runner overslides third base and
is tagged out, the official scorer shall credit him with a two-base
hit.
Rule 9.06(c) Comment:  If the batter-runner overruns second or
third base and is tagged out trying to return, the official scorer
shall credit the batter-runner with the last base he touched. If a
batter-runner runs past second base after reaching that base on
his feet, attempts to return and is tagged out, the official scorer
shall credit the batter with a two-base hit. If a batter-runner

runs past third base after reaching that base on his feet,
attempts to return and is tagged out, the official scorer shall
credit the batter with a three-base hit.
(d) When the batter, after making a safe hit, is called out for having
failed to touch a base, the last base the batter reached safely
shall determine if the official scorer shall credit him with a one-
base hit, a two-base hit or a three-base hit. If a batter-runner is
called out after missing home plate, the official scorer shall
credit him with a three-base hit. If a batter-runner is called out
for missing third base, the official scorer shall credit him with a
two-base hit. If a batter-runner is called out for missing second
base, the official scorer shall credit him with a one-base hit. If a
batter-runner is called out for missing first base, the official
scorer shall charge him with a time at bat, but no hit.
(e) When a batter-runner is awarded two bases, three bases or a
home run under the provisions of Rules 5.06(b)(4) or 6.01(h),
the official scorer shall credit the batter-runner with a two-base
hit, a three-base hit or a home run, as the case may be.
(f ) Subject to the provisions of Rule 9.06(g), when a batter ends a
game with a safe hit that drives in as many runs as are neces-
sary to put his team in the lead, the official scorer shall credit
such batter with only as many bases on his hit as are advanced
by the runner who scores the winning run, and then only if the
batter runs out his hit for as many bases as are advanced by the
runner who scores the winning run.
Rule 9.06 ( f ) Comment:  The official scorer shall apply this
rule even when the batter is theoretically entitled to more bases
because of being awarded an "automatic" extra-base hit under
various provisions of Rules 5.05 and 5.06(b)(4).
The official scorer shall credit the batter with a base touched in
the natural course of play, even if the winning run has scored
moments before on the same play. For example, the score is
tied in the bottom of the ninth inning with a runner on second
base and the batter hits a ball to the outfield that falls for a base
hit. The runner scores after the batter has touched first base and
continued on to second base but shortly before the batter-runner

reaches second base. If the batter-runner reaches second base,
the official scorer shall credit the batter with a two-base hit.
(g) When the batter ends a game with a home run hit out of the
playing field, the batter and any runners on base are entitled to
score.
9.07 Stolen Bases and Caught Stealing
The official scorer shall credit a stolen base to a runner whenever
the runner advances one base unaided by a hit, a putout, an error, a
force-out, a fielder's choice, a passed ball, a wild pitch or a balk,
subject to the following:
(a) When a runner starts for the next base before the pitcher delivers
the ball and the pitch results in what ordinarily is scored a wild
pitch or passed ball, the official scorer shall credit the runner
with a stolen base and shall not charge the misplay, unless, as a
result of the misplay, the stealing runner advances an extra base,
or another runner also advances, in which case the official scorer
shall score the wild pitch or passed ball as well as the stolen base.
(b) When a runner is attempting to steal, and the catcher, after
receiving the pitch, makes a wild throw trying to prevent the
stolen base, the official scorer shall credit the runner with a
stolen base. The official scorer shall not charge an error unless
the wild throw permits the stealing runner to advance one or
more extra bases, or permits another runner to advance, in
which case the official scorer shall credit the runner with the
stolen base and charge one error to the catcher.
(c) When a runner, attempting to steal, or after being picked off
base, evades being put out in a run-down play and advances to
the next base without the aid of an error, the official scorer shall
credit the runner with a stolen base. If another runner also
advances on the play, the official scorer shall credit both run-
ners with stolen bases. If a runner advances while another run-
ner, attempting to steal, evades being put out in a run-down
play and returns safely, without the aid of an error, to the base
he originally occupied, the official scorer shall credit a stolen
base to the runner who advances.

(d) When a double- or triple-steal is attempted and one runner is
thrown out before reaching and holding the base such runner is
attempting to steal, no other runner shall be credited with a
stolen base.
(e) When a runner is tagged out after oversliding a base, while
attempting either to return to that base or to advance to the next
base, the official scorer shall not credit such runner with a
stolen base.
(f ) When in the scorer's judgment a runner attempting to steal is
safe because of a muffed throw, the official scorer shall not
credit a stolen base. The official scorer shall credit an assist to
the fielder who made the throw, charge an error to the fielder
who muffed the throw and charge the runner with "caught
stealing."
(g) The official scorer shall not score a stolen base when a runner
advances solely because of the defensive team's indifference to
the runner's advance. The official scorer shall score such a play
as a fielder's choice.
Rule 9.07(g) Comment:  The scorer shall consider, in judging
whether the defensive team has been indifferent to a runner's
advance, the totality of the circumstances, including the inning
and score of the game, whether the defensive team had held the
runner on base, whether the pitcher had made any pickoff
attempts on that runner before the runner's advance, whether
the fielder ordinarily expected to cover the base to which the
runner advanced made a move to cover such base, whether the
defensive team had a legitimate strategic motive to not contest
the runner's advance or whether the defensive team might be
trying impermissibly to deny the runner credit for a stolen
base. For example, with runners on first and third bases, the
official scorer should ordinarily credit a stolen base when the
runner on first advances to second, if, in the scorer's judgment,
the defensive team had a legitimate strategic motivenamely,
preventing the runner on third base from scoring on the throw
to second basenot to contest the runner's advance to second
base. The official scorer may conclude that the defensive team
is impermissibly trying to deny a runner credit for a stolen base

if, for example, the defensive team fails to defend the advance
of a runner approaching a league or career record or a league
statistical title.
(h) The official scorer shall charge a runner as "caught stealing" if
such runner is put out, or would have been put out by errorless
play, when such runner
(1) tries to steal;
(2) is picked off a base and tries to advance (any move
toward the next base shall be considered an attempt to
advance); or
(3) overslides while stealing.
Rule 9.07(h) Comment: In those instances where a pitched ball
eludes the catcher and the runner is put out trying to advance,
the official scorer shall not charge any "caught stealing." The
official scorer shall not charge any caught stealing when a run-
ner is awarded a base due to obstruction or when a runner is
called out due to interference by the batter. The official scorer
shall not charge a runner with a caught stealing if such runner
would not have been credited with a stolen base had such run-
ner been safe (for example, when a catcher throws the runner
out after such runner tries to advance after a ball that had
eluded the catcher on a pitch).
9.08 Sacrifices
The official scorer shall:
(a) Score a sacrifice bunt when, before two are out, the batter
advances one or more runners with a bunt and is put out at first
base, or would have been put out except for a fielding error,
unless, in the judgment of the official scorer, the batter was
bunting exclusively for a base hit and not sacrificing his own
chance of reaching first base for the purpose of advancing a
runner or runners, in which case the official scorer shall charge
the batter with a time at bat;
Rule 9.08(a) Comment:  In determining whether the batter had
been sacrificing his own chance of reaching first base for the

purpose of advancing a runner, the official scorer shall give the
batter the benefit of the doubt. The official scorer shall con-
sider the totality of the circumstances of the at-bat, including
the inning, the number of outs and the score.
(b) Score a sacrifice bunt when, before two are out, the fielders
handle a bunted ball without error in an unsuccessful attempt to
put out a preceding runner advancing one base, unless, an
attempt to turn a bunt into a putout of a preceding runner fails,
and in the judgment of the official scorer ordinary effort would
not have put out the batter at first base, in which case the batter
shall be credited with a one-base hit and not a sacrifice;
(c) Not score a sacrifice bunt when any runner is put out attempt-
ing to advance one base on a bunt, or would have been put out,
except for a fielding error, in which case the official scorer
shall charge the batter with a time at bat; and
(d) Score a sacrifice fly when, before two are out, the batter hits a
ball in flight handled by an outfielder or an infielder running in
the outfield in fair or foul territory that
(1) is caught, and a runner scores after the catch, or
(2) is dropped, and a runner scores, if in the scorer's judg-
ment the runner could have scored after the catch had the
fly been caught.
Rule 9.08(d) Comment:  The official scorer shall score a sacri-
fice fly in accordance with Rule 9.08(d)(2) even though
another runner is forced out by reason of the batter becoming a
runner.
9.09 Putouts
A putout is a statistic credited to a fielder whose action causes the out
of a batter-runner or runner, as set forth in this Rule 9.09.
(a) The official scorer shall credit a putout to each fielder who
(1) catches a ball that is in flight, whether fair or foul;
(2) catches a batted or thrown ball and tags a base to put out
a batter or runner; or

fielder with a putout if such fielder catches a thrown ball and
tags a base to record an out on an appeal play.
(3) tags a runner when the runner is off the base to which the
runner is entitled.
(b) The official scorer shall credit an automatic putout to the
catcher when a:
(1) batter is called out on strikes;
(2) batter is called out for an illegally batted ball;
(3) batter is called out for bunting foul for his third strike;
Rule 9.09(b)(3) Comment:  Note the exception in Rule
9.15(a)(4).
(4) batter is called out for being touched by his own batted
ball;
(5) batter is called out for interfering with the catcher;
(6) batter is called out for failing to bat in his proper turn;
Rule 9.09(b)(6) Comment:  See Rule 9.03(d).
(7) batter is called out for refusing to touch first base after
receiving a base on balls, after being hit by a pitch or
after a catcher's interference; or
(8) runner is called out for refusing to advance from third
base to home plate.
(c) The official scorer shall credit automatic putouts as follows
(and shall credit no assists on these plays except as specified):
(1) When the batter is called out on an Infield Fly that is not
caught, the official scorer shall credit the putout to the
fielder who the scorer believes could have made the
catch;
(2) When a runner is called out for being touched by a fair
ball (including an Infield Fly), the official scorer shall

credit the putout to the fielder nearest the ball;
(3) When a runner is called out for running out of line to
avoid being tagged, the official scorer shall credit the
putout to the fielder whom the runner avoided;
(4) When a runner is called out for passing another runner,
the official scorer shall credit the putout to the fielder
nearest the point of passing;
(5) When a runner is called out for running the bases in
reverse order, the official scorer shall credit the putout to
the fielder covering the base the runner left in starting his
reverse run;
(6) When a runner is called out for having interfered with a
fielder, the official scorer shall credit the putout to the
fielder with whom the runner interfered, unless the
fielder was in the act of throwing the ball when the inter-
ference occurred, in which case the official scorer shall
credit the putout to the fielder for whom the throw was
intended and shall credit an assist to the fielder whose
throw was interfered with; or
(7) When the batter-runner is called out because of interfer-
ence by a preceding runner, as provided in Rule
6.01(a)(5), the official scorer shall credit the putout to the
first baseman. If the fielder interfered with was in the act
of throwing the ball, the official scorer shall credit such
fielder with an assist but shall credit only one assist on any
one play under the provisions of Rules 9.09(c)(6) and
9.09(c)(7).
9.10 Assists
An assist is a statistic credited to a fielder whose action contributes
to a batter-runner or runner being put out, as set forth in this Rule
9.10.
(a) The official scorer shall credit an assist to each fielder who
(1) throws or deflects a batted or thrown ball in such a way
that a putout results, or would have resulted except for a
subsequent error by any fielder. Only one assist and no

more shall be credited to each fielder who throws or
deflects the ball in a run-down play that results in a
putout, or would have resulted in a putout, except for a
subsequent error; or
Rule 9.10(a )(1) Comment:  Mere ineffective contact with the
ball shall not be considered an assist. "Deflect" shall mean to
slow down or change the direction of the ball and thereby effec-
tively assist in putting out a batter or runner. If a putout results
from an appeal play within the natural course of play, the offi-
cial scorer shall give assists to each fielder, except the fielder
making the putout, whose action led to the putout. If a putout
results from an appeal play initiated by the pitcher throwing to
a fielder after the previous play has ended, the official scorer
shall credit the pitcher, and only the pitcher, with an assist.
(2) throws or deflects the ball during a play that results in a
runner being called out for interference or for running out
of line.
(b) The official scorer shall not credit an assist to
(1) the pitcher on a strikeout, unless the pitcher fields an
uncaught third strike and makes a throw that results in a
putout;
(2) the pitcher when, as the result of a legal pitch received by
the catcher, a runner is put out, as when the catcher picks
a runner off base, throws out a runner trying to steal or
tags a runner trying to score; or
(3) a fielder whose wild throw permits a runner to advance,
even though the runner subsequently is put out as a result
of continuous play. A play that follows a misplay
(whether or not the misplay is an error) is a new play, and
the fielder making any misplay shall not be credited with
an assist unless such fielder takes part in the new play.
9.11 Double and Triple Plays
The official scorer shall credit participation in a double play or
triple play to each fielder who earns a putout or an assist when two
or three players are put out between the time a pitch is delivered

and the time the ball next becomes dead or is next in possession of
the pitcher in a pitching position, unless an error or misplay inter-
venes between putouts.
Rule 9.11 Comment:  The official scorer shall credit a double
play or triple play also if an appeal play after the ball is in pos-
session of the pitcher results in an additional putout.
9.12 Errors
An error is a statistic charged against a fielder whose action has
assisted the team on offense, as set forth in this Rule 9.12.
(a) The official scorer shall charge an error against any fielder:
(1) whose misplay (fumble, muff or wild throw) prolongs the
time at bat of a batter, prolongs the presence on the bases
of a runner or permits a runner to advance one or more
bases, unless, in the judgment of the official scorer, such
fielder deliberately permits a foul fly to fall safe with a
runner on third base before two are out in order that the
runner on third shall not score after the catch;
Rule 9.12(a )(1) Comment:  Slow handling of the ball that does
not involve mechanical misplay shall not be construed as an
error.  For example, the official scorer shall not charge a fielder
with an error if such fielder fields a ground ball cleanly but does
not throw to first base in time to retire the batter. It is not neces-
sary that the fielder touch the ball to be charged with an error. If
a ground ball goes through a fielder's legs or a fly ball falls
untouched and, in the scorer's judgment, the fielder could have
handled the ball with ordinary effort, the official scorer shall
charge such fielder with an error. For example, the official
scorer shall charge an infielder with an error when a ground ball
passes to either side of such infielder if, in the official scorer's
judgment, a fielder at that position making ordinary effort
would have fielded such ground ball and retired a runner. The
official scorer shall charge an outfielder with an error if such
outfielder allows a fly ball to drop to the ground if, in the official
scorer's judgment, an outfielder at that position making ordinary
effort would have caught such fly ball. If a throw is low, wide or

high, or strikes the ground, and a runner reaches base who oth-
erwise would have been put out by such throw, the official
scorer shall charge the player making the throw with an error.
The official scorer shall not score mental mistakes or misjudg-
ments as errors unless a specific rule prescribes otherwise. A
fielder's mental mistake that leads to a physical misplay
such as throwing the ball into the stands or rolling the ball to
the pitcher's mound, mistakenly believing there to be three
outs, and thereby allowing a runner or runners to advance
shall not be considered a mental mistake for purposes of this
rule and the official scorer shall charge a fielder committing
such a mistake with an error. The official scorer shall not
charge an error if the pitcher fails to cover first base on a play,
thereby allowing a batter-runner to reach first base safely. The
official scorer shall not charge an error to a fielder who incor-
rectly throws to the wrong base on a play.
The official scorer shall charge an error to a fielder who causes
another fielder to misplay a ballfor example, by knocking
the ball out of the other fielder's glove. On such a play, when
the official scorer charges an error to the interfering fielder, the
official scorer shall not charge an error to the fielder with
whom the other fielder interfered.
(2) when such fielder muffs a foul fly to prolong the time at
bat of a batter, whether the batter subsequently reaches
first base or is put out;
(3) when such fielder catches a thrown ball or a ground ball
in time to put out the batter-runner and fails to tag first
base or the batter-runner;
(4) when such fielder catches a thrown ball or a ground ball
in time to put out any runner on a force play and fails to
tag the base or the runner;
(5) whose wild throw permits a runner to reach a base safely,
when in the scorer's judgment a good throw would have
put out the runner, unless such wild throw is made
attempting to prevent a stolen base;

(6) whose wild throw in attempting to prevent a runner's
advance permits that runner or any other runner to
advance one or more bases beyond the base such runner
would have reached had the throw not been wild;
(7) whose throw takes an unnatural bounce, touches a base
or the pitcher's plate, or touches a runner, a fielder or an
umpire, thereby permitting any runner to advance; or
Rule 9.12(a)(7) Comment:  The official scorer shall apply this
rule even when it appears to be an injustice to a fielder whose
throw was accurate. For example, the official scorer shall
charge an error to an outfielder whose accurate throw to second
base hits the base and caroms back into the outfield, thereby
permitting a runner or runners to advance, because every base
advanced by a runner must be accounted for.
(8) whose failure to stop, or try to stop, an accurately thrown
ball permits a runner to advance, so long as there was
occasion for the throw. If such throw was made to second
base, the official scorer shall determine whether it was
the duty of the second baseman or the shortstop to stop
the ball and shall charge an error to the negligent fielder.
Rule 9.12(a )(8) Comment: If, in the official scorer's judg-
ment, there was no occasion for the throw, the official scorer
shall charge an error to the fielder who threw the ball.
(b) The official scorer shall charge only one error on any wild
throw, regardless of the number of bases advanced by one or
more runners.
(c) When an umpire awards the batter or any runner or runners one
or more bases because of interference or obstruction, the offi-
cial scorer shall charge the fielder who committed the interfer-
ence or obstruction with one error, no matter how many bases
the batter, or runner or runners, may advance.
Rule 9.12(c) Comment:  The official scorer shall not charge an
error if obstruction does not change the play, in the opinion of
the scorer.
(d) The official scorer shall not charge an error against:

(1) the catcher when the catcher, after receiving the pitch,
makes a wild throw attempting to prevent a stolen base,
unless the wild throw permits the stealing runner to
advance one or more extra bases or permits any other
runner to advance one or more bases;
(2) any fielder who makes a wild throw if in the scorer's
judgment the runner would not have been put out with
ordinary effort by a good throw, unless such wild throw
permits any runner to advance beyond the base he would
have reached had the throw not been wild;
(3) any fielder who makes a wild throw in attempting to com-
plete a double play or triple play, unless such wild
throw enables any runner to advance beyond the base such
runner would have reached had the throw not been wild;
Rule 9.12(d) Comment:  When a fielder muffs a thrown ball
that, if held, would have completed a double play or triple play,
the official scorer shall charge an error to the fielder who drops
the ball and credit an assist to the fielder who made the throw.
(4) any fielder when, after a ground ball or dropping a batted
ball that is in flight or a thrown ball, the fielder recovers
the ball in time to force out a runner at any base; or
(5) any fielder when a wild pitch or passed ball is scored.
(e) The official scorer shall not charge an error when the batter is
awarded first base on four called balls, when the batter is
awarded first base when touched by a pitched ball, or when the
batter reaches first base as the result of a wild pitch or passed
ball.
Rule 9.12(e) Comment: See Rule 9.13 for additional scoring
rules relating to wild pitches and passed balls.
(f ) The official scorer shall not charge an error when a runner or run-
ners advance as the result of a passed ball, a wild pitch or a balk.

ball and as a result

base;
           (B)  any runner forced to advance by the base on balls
advances more than one base; or
           (C)  any runner, not forced to advance, advances one
or more bases, the official scorer shall score the
base on balls and also the wild pitch or passed
ball, as the case may be.
(2) When the catcher recovers the ball after a wild pitch or
passed ball on the third strike, and throws out the batter-
runner at first base, or tags out the batter-runner, but
another runner or runners advance, the official scorer
shall score the strikeout, the putout and assists, if any, and
credit the advance of the other runner or runners on the
play as a fielder's choice.
Rule 9.12( f ) Comment:  See Rule 9.13 for additional scoring
rules relating to wild pitches and passed balls.
9.13 Wild Pitches and Passed Balls
A wild pitch is defined in the Definition of Terms (Wild Pitch).  A
passed ball is a statistic charged against a catcher whose action has
caused a runner or runners to advance, as set forth in this Rule 9.13.
(a) The official scorer shall charge a pitcher with a wild pitch
when a legally delivered ball is so high, so wide or so low that
the catcher does not stop and control the ball by ordinary effort,
thereby permitting a runner or runners to advance. The official
scorer shall charge a pitcher with a wild pitch when a legally
delivered ball touches the ground or home plate before reach-
ing the catcher and is not handled by the catcher, thereby per-
mitting a runner or runners to advance. When the third strike is
a wild pitch, permitting the batter to reach first base, the offi-
cial scorer shall score a strikeout and a wild pitch.
(b) The official scorer shall charge a catcher with a passed ball
when the catcher fails to hold or to control a legally pitched ball
that should have been held or controlled with ordinary effort,

thereby permitting a runner or runners to advance. When the
third strike is a passed ball, permitting the batter to reach first
base, the official scorer shall score a strikeout and a passed ball.
Rule 9.13 Comment:  The official scorer shall not charge a wild
pitch or passed ball if the defensive team makes an out before
any runners advance. For example, if a pitch touches the
ground and eludes the catcher with a runner on first base, but
the catcher recovers the ball and throws to second base in time
to retire the runner, the official scorer shall not charge the
pitcher with a wild pitch. The official scorer shall credit the
advancement of any other runner on the play as a fielder's
choice. If a catcher drops a pitch, for example, with a runner on
first base, but the catcher recovers the ball and throws to sec-
ond base in time to retire the runner, the official scorer shall not
charge the catcher with a passed ball. The official scorer shall
credit the advancement of any other runner on the play as a
fielder's choice.
See Rules 9.07(a), 9.12(e) and 9.12(f) for additional scoring
rules relating to wild pitches and passed balls.
9.14 Base on Balls
A base on balls is defined in the Definition of Terms (Base on
Balls).
(a) The official scorer shall score a base on balls whenever a batter
is awarded first base because of four balls having been pitched
outside the strike zone, but when the fourth such ball touches
the batter it shall be scored as a "hit batter."
Rule 9.14(a) Comment:  See Rule 9.16(h) for the procedure
when more than one pitcher is involved in giving a base on
balls.  See also Rule 9.15, which addresses situations in which
a substitute batter receives a base on balls.
(b) The official scorer shall score an intentional base on balls when
the pitcher makes no attempt to throw the last pitch to the bat-
ter into the strike zone, but purposely throws the ball wide to
the catcher outside the catcher's box.

(c) If a batter awarded a base on balls is called out for refusing to
advance to first base, the official scorer shall not credit the base
on balls and shall charge a time at bat.
(d) The official scorer shall score an intentional base on balls
when a batter is awarded first base because the defensive
team's manager informs the umpire of the team's intention to
walk the batter.
9.15 Strikeouts
A strikeout is a statistic credited to a pitcher and charged to a batter
when the umpire calls three strikes on a batter, as set forth in this
Rule 9.15.
(a) The official scorer shall score a strikeout whenever a batter:
(1) is put out by a third strike caught by the catcher;
(2) is put out by a third strike not caught when there is a run-
ner on first before two are out;
(3) becomes a runner because a third strike is not caught; or
(4) bunts foul on third strike, unless such bunt on third strike
results in a foul fly caught by any fielder, in which case
the official scorer shall not score a strikeout and shall
credit the fielder who catches such foul fly with a putout.
(b) When a batter leaves the game with two strikes against him,
and the substitute batter completes a strikeout, the official
scorer shall charge the strikeout and the time at bat to the first
batter. If the substitute batter completes the turn at bat in any
other manner, including a base on balls, the official scorer shall
score the action as having been that of the substitute batter.
9.16 Earned Runs and Runs Allowed
An earned run is a run for which a pitcher is held accountable. In
determining earned runs, the official scorer shall reconstruct the
inning without the errors (which exclude catcher's interference)
and passed balls, giving the benefit of the doubt always to the
pitcher in determining which bases would have been reached by
runners had there been errorless play. For the purpose of determin-

ing earned runs, an intentional base on balls, regardless of the cir-
cumstances, shall be construed in exactly the same manner as any
other base on balls.
(a) The official scorer shall charge an earned run against a pitcher
every time a runner reaches home base by the aid of safe hits,
sacrifice bunts, a sacrifice fly, stolen bases, putouts, fielder's
choices, bases on balls, hit batters, balks or wild pitches
(including a wild pitch on third strike that permits a batter to
reach first base) before fielding chances have been offered to
put out the offensive team. For the purpose of this rule, a defen-
sive interference penalty shall be construed as a fielding
chance. A wild pitch is solely the pitcher's fault and shall con-
tribute to an earned run just as a base on balls or a balk.
Rule 9.16(a) Comment: The following are examples of earned
runs charged to a pitcher:
(1) Peter pitches and retires Abel and Baker, the first two
batters of an inning. Charlie reaches first base on an
error charged to a fielder. Daniel hits a home run.
Edward hits a home run. Peter retires Frank to end the
inning. Three runs have scored, but no earned runs are
charged to Peter, because Charlie should have been the
third out of the inning, as reconstructed without the
error.
(2) Peter pitches and retires Abel. Baker hits a triple. While
pitching to Charlie, Peter throws a wild pitch, allowing
Baker to score. Peter retires Daniel and Edward.  One
run has scored, charged as an earned run to Peter,
because the wild pitch contributes to an earned run.
In an inning in which a batter-runner reaches first base
on a catcher's interference, such batter-runner shall not
count as an earned run should he subsequently score.
The official scorer shall not assume, however, that such
batter would have made an out absent the catcher's inter-
ference (unlike, for example, situations in which a bat-
ter-runner reaches first base safely because of a fielder's
misplay of a ball for an error). Because such batter never

had a chance to complete his time at bat, it is unknown
how such batter would have fared absent the catcher's
interference.  Compare the following examples:
(3) With two out, Abel reaches first on an error by the short-
stop in misplaying a ground ball. Baker hits a home run.
Charlie strikes out.  Two runs have scored, but none is
earned, because Abel's at-bat should have been the third
out of the inning, as reconstructed without the error.
(4) With two out, Abel reaches first on a catcher's interfer-
ence.  Baker hits a home run. Charlie strikes out.  Two
runs have scored, but one (Baker's) is earned, because the
official scorer cannot assume that Abel would have made
an out to end the inning, absent the catcher's interference.
(b) No run shall be earned when scored by a runner who reaches
first base
(1) on a hit or otherwise after his time at bat is prolonged by
a muffed foul fly;
(2) because of interference or obstruction; or
(3) because of any fielding error.
(c) No run shall be earned when scored by a runner whose pres-
ence on the bases is prolonged by an error, if such runner
would have been put out by errorless play.
(d) No run shall be earned when the scoring runner's advance has
been aided by an error, a passed ball or defensive interference
or obstruction, if in the official scorer's judgment the run
would not have scored without the aid of such misplay.
(e) An error by a pitcher is treated exactly the same as an error by
any other fielder in computing earned runs.
(f ) Whenever a fielding error occurs, the pitcher shall be given the
benefit of the doubt in determining to which bases any runners
would have advanced had the fielding of the defensive team
been errorless.
(g) When pitchers are changed during an inning, the official scorer
shall not charge the relief pitcher with any run (earned or

unearned) scored by a runner who was on base at the time such
relief pitcher entered the game, nor for runs scored by any run-
ner who reaches base on a fielder's choice that puts out a run-
ner left on base by any preceding pitcher.
Rule 9.16(g) Comment:  It is the intent of Rule 9.16 (g) to
charge each pitcher with the number of runners he put on base,
rather than with the individual runners. When a pitcher puts
runners on base and is relieved, such pitcher shall be charged
with all runs subsequently scored up to and including the num-
ber of runners such pitcher left on base when such pitcher left
the game, unless such runners are put out without action by the
batter (i.e., caught stealing, picked off base or called out for
interference when a batter-runner does not reach first base on
the play). For example:
(1) Peter is pitching.  Abel reaches first base on a base on
balls.  Roger relieves Peter. Baker grounds out, advanc-
ing Abel to second base.  Charlie flies out.  Daniel sin-
gles, scoring Abel.  Abel's run is charged to Peter.
(2) Peter is pitching. Abel reaches first base on a base on
balls. Roger relieves Peter. Baker forces Abel at second
bases. Charlie grounds out, advancing Baker to second
base. Daniel singles, scoring Baker. Baker's run is
charged to Peter.
(3) Peter is pitching. Abel reaches first base on a base on
balls. Roger relieves Peter. Baker singles, advancing
Abel to third base. Charlie grounds to short, with Abel
out at home plate and Baker advancing to second base.
Daniel flies out. Edward singles, scoring Baker. Baker's
run is charged to Peter.
(4) Peter is pitching. Abel reaches first base on a base on
balls.  Roger relieves  Peter. Baker reaches on a base on
balls.  Charlie flies out.  Abel is picked off second base.
Daniel doubles, scoring Baker from first base.  Baker's
run is charged to Roger.
(5) Peter is pitching. Abel reaches first base on a base on
balls. Roger relieves Peter.  Baker reaches first base on a

Abel at third base.  Daniel forces Baker at third base.
Edward hits a home run, scoring three runs.  The official
scorer shall charge one run to Peter, one run to Roger
and one run to Sierra.
(6) Peter is pitching. Abel reaches first base on a base on
balls. Roger relieves Peter. Baker reaches first base on a
base on balls. Charlie singles, filling the bases. Daniel
forces Abel at home plate. Edward singles, scoring
Baker and Charlie. The official scorer shall charge one
run to Peter and one run to Roger.
(7) Peter is pitching. Abel reaches first base on a base on
balls. Roger relieves Peter. Baker singles, but Abel is
out trying to reach third base and Baker advances to
second base on the throw. Charlie singles, scoring
Baker. Baker's run is charged to Roger.
(h) A relief pitcher shall not be held accountable when the first bat-
ter to whom he pitches reaches first base on four called balls if
such batter has a decided advantage in the ball and strike count
when pitchers are changed.

pitcher, not to the relief pitcher.
(2) Any other action by such batter, such as reaching base on
a hit, an error, a fielder's choice, a force-out, or being
touched by a pitched ball, shall cause such a batter to be
charged to the relief pitcher.

Rule 9.16(h ) Comment:  The provisions of Rule 9.16(h)(2)
shall not be construed as affecting or conflicting with the pro-
visions of Rule 9.16(g).
(3) If, when pitchers are changed, the count is
2 balls, 2 strikes,
1 ball, 2 strikes,
1 ball, 1 strike,
1 ball, no strike,
no ball, 2 strikes,
no ball, 1 strike,
(1) the official scorer shall charge that batter and the actions
of that batter to the relief pitcher.
(i) When pitchers are changed during an inning, the relief pitcher
shall not have the benefit of previous chances for outs not
accepted in determining earned runs.
Rule 9.16(i) Comment:  It is the intent of Rule 9.16 (i) to
charge a relief pitcher with earned runs for which such relief
pitcher is solely responsible.  In some instances, runs charged
as earned against the relief pitcher can be charged as unearned
against the team. For example:
(1) With two out and Peter pitching, Abel reaches first base
on a base on balls. Baker reaches first base on an error.
Roger relieves Peter.  Charlie hits a home run, scoring
three runs. The official scorer shall charge two unearned
runs to Peter, one earned run to Roger and three
unearned runs to the team (because the inning should
have ended with the third out when Baker batted and an
error was committed).
(2) With two out, and Peter pitching, Abel and Baker each
reach first base on a base on balls. Roger relieves Peter.
Charlie reaches first base on an error. Daniel hits a
home run, scoring four runs. The official scorer shall
charge two unearned runs to Peter and two unearned
runs to Roger (because the inning should have ended

with the third out when Charlie batted and an error was

(3) With none out and Peter pitching, Abel reaches first
base on a base on balls. Baker reaches first base on an
error. Roger relieves Peter. Charlie hits a home run,
scoring three runs. Daniel and Edward strike out. Frank
reaches first base on an error. George hits a home run,
scoring two runs. The official scorer shall charge two
runs, one of them earned, to Peter, three runs, one of
them earned, to Roger and five runs, two of them
earned, to the team (because only Abel and Charlie
would have scored in an inning reconstructed without
the errors).
9.17 Winning and Losing Pitcher
(a) The official scorer shall credit as the winning pitcher that
pitcher whose team assumes a lead while such pitcher is in the
game, or during the inning on offense in which such pitcher is
removed from the game, and does not relinquish such lead,
unless
(1) such pitcher is a starting pitcher and Rule 9.17(b)
applies; or (2) Rule 9.17(c) applies.
Rule 9.17(a) Comment:  Whenever the score is tied, the game
becomes a new contest insofar as the winning pitcher is con-
cerned.  Once the opposing team assumes the lead, all pitchers
who have pitched up to that point and have been replaced are
excluded from being credited with the victory.  If the pitcher
against whose pitching the opposing team gained the lead con-
tinues to pitch until his team regains the lead, which it holds to
the finish of the game, that pitcher shall be the winning pitcher.
(b) If the pitcher whose team assumes a lead while such pitcher is
in the game, or during the inning on offense in which such
pitcher is removed from the game, and does not relinquish such
lead, is a starting pitcher who has not completed
(1) five innings of a game that lasts six or more innings on
defense, or

(2) four innings of a game that lasts five innings on defense, 
then the official scorer shall credit as the winning pitcher the
relief pitcher, if there is only one relief pitcher, or the relief
pitcher who, in the official scorer's judgment was the most
effective, if there is more than one relief pitcher.
Rule 9.17(b) Comment:  It is the intent of Rule 9.17(b) that a
relief pitcher pitch at least one complete inning or pitch when a
crucial out is made, within the context of the game (including
the score), in order to be credited as the winning pitcher. If the
first relief pitcher pitches effectively, the official scorer should
not presumptively credit that pitcher with the win, because the
rule requires that the win be credited to the pitcher who was the
most effective, and a subsequent relief pitcher may have been
most effective. The official scorer, in determining which relief
pitcher was the most effective, should consider the number of
runs, earned runs and base runners given up by each relief
pitcher and the context of the game at the time of each relief
pitcher's appearance. If two or more relief pitchers were simi-
larly effective, the official scorer should give the presumption
to the earlier pitcher as the winning pitcher.
(c) The official scorer shall not credit as the winning pitcher a
relief pitcher who is ineffective in a brief appearance, when at
least one succeeding relief pitcher pitches effectively in helping
his team maintain its lead. In such a case, the official scorer
shall credit as the winning pitcher the succeeding relief pitcher
who was most effective, in the judgment of the official scorer.
Rule 9.17(c) Comment:  The official scorer generally should,
but is not required to, consider the appearance of a relief
pitcher to be ineffective and brief if such relief pitcher pitches
less than one inning and allows two or more earned runs to
score (even if such runs are charged to a previous pitcher).
Rule 9.17(b) Comment provides guidance on choosing the
winning pitcher from among several succeeding relief pitchers.
(d) A losing pitcher is a pitcher who is responsible for the run that
gives the winning team a lead that the winning team does not
relinquish.

Rule 9.17(d) Comment:  Whenever the score is tied, the game
becomes a new contest insofar as the losing pitcher is con-
cerned.
(e) A league may designate a non-championship game (for exam-
ple, the Major League All-Star Game) for which Rules
9.17(a)(1) and 9.17(b) do not apply.  In such games, the offi-
cial scorer shall credit as the winning pitcher that pitcher whose
team assumes a lead while such pitcher is in the game, or dur-
ing the inning on offense in which such pitcher is removed
from the game, and does not relinquish such lead, unless such
pitcher is knocked out after the winning team has attained a
commanding lead and the official scorer concludes that a sub-
sequent pitcher is entitled to credit as the winning pitcher.
9.18 Shutouts
A shutout is a statistic credited to a pitcher who allows no runs in a
game. No pitcher shall be credited with pitching a shutout unless he
pitches the complete game, or unless he enters the game with none
out before the opposing team has scored in the first inning, puts out
the side without a run scoring and pitches the rest of the game with-
out allowing a run. When two or more pitchers combine to pitch a
shutout, the league statistician shall make a notation to that effect in
the league's official pitching records.
9.19 Saves for Relief Pitchers
A save is a statistic credited to a relief pitcher, as set forth in this
Rule 9.19.
The official scorer shall credit a pitcher with a save when such
pitcher meets all four of the following conditions:
(a) He is the finishing pitcher in a game won by his team;
(b) He is not the winning pitcher;
(c) He is credited with at least 13 of an inning pitched; and
(d) He satisfies one of the following conditions:
(1) He enters the game with a lead of no more than three runs
and pitches for at least one inning;

(2) He enters the game, regardless of the count, with the
potential tying run either on base, or at bat or on deck
(that is, the potential tying run is either already on base or
is one of the first two batters he faces); or
(3) He pitches for at least three innings.
9.20 Statistics
The League President shall appoint an official statistician.  The
statistician shall maintain an accumulative record of all the batting,
fielding, running and pitching records specified in Rule 9.02 for
every player who appears in a league championship game or post-
season game.
The statistician shall prepare a tabulated report at the end of the
season, including all individual and team records for every champi-
onship game, and shall submit this report to the League President.
This report shall identify each player by his first name and surname
and shall indicate as to each batter whether he bats righthanded,
lefthanded or both ways, and as to each fielder and pitcher, whether
he throws righthanded or lefthanded.
When a player listed in the starting lineup is substituted for before
he plays on defense, he shall not receive credit in the defensive sta-
tistics (fielding) unless he actually plays that position during the
game.  All such players, however, shall be credited with one game
played (in batting statistics) so long as they are announced into the
game or listed on the official lineup card.
Rule 9.20 Comment: The official scorer shall credit a player
with having played on defense if such player is on the field for
at least one pitch or play.  If a game is called (for example,
because of rain) after a substitute player enters the field but
before a pitch is thrown or a play is made, the official scorer
shall credit such player with a game played in the batting sta-
tistics but shall not credit such player in any defensive statis-
tics.  If a game is called (for example, because of rain) after a
relief pitcher enters the field but before a pitch is thrown or a
play is made, the official scorer shall credit such pitcher with a
game played in the batting statistics but shall not credit such
pitcher in any defensive statistics or with a game pitched.

statistics for that championship season.
9.21 Determining Percentage Records
To compute:
(a) Percentage of games won and lost, divide the number of games
won by the sum of games won and games lost;
(b) Batting average, divide the total number of safe hits (not the
total bases on hits) by the total times at bat, as defined in Rule
9.02(a);
(c) Slugging percentage, divide the total bases of all safe hits by
the total times at bat, as defined in Rule 9.02(a);
(d) Fielding average, divide the sum of putouts and assists by the
sum of putouts, assists and errors (which shall be called chances);
(e) Pitcher's earned-run average, multiply the total earned runs
charged against such pitcher by 9, and divide the result by the
total number of innings he pitched, including fractions of an
inning; and
Rule 9.21(e) Comment:  For example, 913 innings pitched and 3
earned runs is an earned-run average of 2.89 (3 earned runs
times 9 divided by 913 equals 2.89).
(f ) On-base percentage, divide the sum of hits, bases on balls and
times hit by pitch by the sum of at-bats, bases on balls, times
hit by pitch and sacrifice flies.
Rule 9.21( f ) Comment:  For the purpose of computing on-base
percentage, ignore instances of a batter being awarded first
base on interference or obstruction.
9.22 Minimum Standards for Individual Championships
To assure uniformity in establishing the batting, pitching and field-
ing championships of professional leagues, such champions shall
meet the following minimum performance standards:
(a) The individual batting, slugging or on-base percentage cham-
pion shall be the player with the highest batting average, slug-

ging percentage or on-base percentage, as the case may be, pro-
vided the player is credited with as many or more total appear-
ances at the plate in league championship games as the number
of games scheduled for each club in his club's league that sea-
son, multiplied by 3.1 in the case of a Major League player and
by 2.7 in the case of a National Association player. Total
appearances at the plate shall include official times at bat, plus
bases on balls, times hit by pitcher, sacrifice hits, sacrifice flies
and times awarded first base because of interference or obstruc-
tion. Notwithstanding the foregoing requirement of minimum
appearances at the plate, any player with fewer than the
required number of plate appearances whose average would be
the highest, if he were charged with the required number of
plate appearances shall be awarded the batting, slugging or on-
base percentage championship, as the case may be.
Rule 9.22(a ) Comment:  For example, if a Major League
schedules 162 games for each club, 502 plate appearances
qualify (162 times 3.1 equals 502) a player for a batting, slug-
ging or on-base percentage championship.  If a National
Association league schedules 140 games for each club, 378
plate appearances qualify (140 times 2.7 equals 378) a player
for a batting, slugging or on-base percentage championship.
Fractions of a plate appearance are to be rounded up or down
to the closest whole number.  For example, 162 times 3.1
equals 502.2, which is rounded down to a requirement of 502.
If, for example, Abel has the highest batting average among
those with 502 plate appearance in a Major League with a .362
batting average (181 hits in 500 at-bats), and Baker has 490 plate
appearances, 440 at-bats and 165 hits for a .375 batting average,
Baker shall be the batting champion, because adding 12 more at-
bats to Baker's record would still give Baker a higher batting
average than Abel:  .365 (165 hits in 452 at-bats) to Abel's .362.
(b) The individual pitching champion in a Major League shall be
the pitcher with the lowest earned-run average, provided that
the pitcher has pitched at least as many innings in league cham-
pionship games as the number of games scheduled for each
club in his club's league that season. The individual pitching
champion in a National Association league shall be the pitcher

with the lowest earned-run average provided that the pitcher
has pitched at least as many innings in league championship
season games as 80% of the number of games scheduled for
each club in the pitcher's league.
Rule 9.22(b) Comment:  For example, if a Major League
schedules 162 games for each club, 162 innings qualify a
pitcher for a pitching championship.  A pitcher with 16123
innings would not qualify. If a National Association league
schedules 140 games for each club, 112 innings qualify a
pitcher for a pitching championship. Fractions of an inning for
the required number of innings are to be rounded to the closest
third of an inning. For example, 80% of 144 games is 115.2, so
11513 innings would be the minimum required for a pitching
championship in a National Association league with 144
games scheduled and 80% of 76 games is 60.8, so 60 23 innings
would be the minimum required for a pitching championship
in a National Association league with 76 games scheduled.
(c) The individual fielding champions shall be the fielders with the
highest fielding average at each position, provided:
(1) A catcher must have participated as a catcher in at least
one-half the number of games scheduled for each club in
his league that season;
(2) An infielder or outfielder must have participated at his
position in at least two-thirds of the number of games
scheduled for each club in his league that season; and
(3) A pitcher must have pitched at least as many innings as
the number of games scheduled for each club in his
league that season, unless another pitcher has a fielding
average as high or higher and has handled more total
chances in fewer innings, in which case such other
pitcher shall be the fielding champion.
9.23 Guidelines for Cumulative Performance Records
(a) Consecutive Hitting Streaks
(a) A consecutive hitting streak shall not be terminated if a batter's
plate appearance results in a base on balls, hit batsman, defen-
sive interference or obstruction or a sacrifice bunt. A sacrifice
fly shall terminate the streak.

(b) Consecutive-Game Hitting Streaks
(b) A consecutive-game hitting streak shall not be terminated if all
of a batter's plate appearances (one or more) in a game result
in a base on balls, hit batsman, defensive interference or
obstruction or a sacrifice bunt. The streak shall terminate if the
player has a sacrifice fly and no hit.
(b) A player's individual consecutive-game hitting streak shall be
determined by the consecutive games in which such player
appears and is not determined by his club's games.
(c) Consecutive-Game Playing Streak
(c) A consecutive-game playing streak shall be extended if a
player plays one half-inning on defense or if the player com-
pletes a time at bat by reaching base or being put out. A pinch-
running appearance only shall not extend the streak.  If a player
is ejected from a game by an umpire before such player can
comply with the requirements of this Rule 9.23(c), such
player's streak shall continue.
(d) Suspended Games
(d) For the purpose of this Rule 9.23 all performances in the com-
pletion of a suspended game shall be considered as occurring
on the original date of the game.

who, during his time at bat, receives four pitches outside the strike zone
or following a signal from the defensive team's manager to the umpire
that he intends to intentionally walk the batter.  If the manager informs

A BUNT is a batted ball not swung at, but intentionally met with
the bat and tapped slowly within the infield.
A CALLED GAME is one in which, for any reason, the umpire-in-
chief terminates play.
A CATCH is the act of a fielder in getting secure possession in his
hand or glove of a ball in flight and firmly holding it; providing he does
not use his cap, protector, pocket or any other part of his uniform in get-
ting possession. It is not a catch, however, if simultaneously or immedi-
ately following his contact with the ball, he collides with a player, or with
a wall, or if he falls down, and as a result of such collision or falling, drops
the ball. It is not a catch if a fielder touches a fly ball which then hits a
member of the offensive team or an umpire and then is caught by another
defensive player. In establishing the validity of the catch, the fielder shall
hold the ball long enough to prove that he has complete control of the ball
and that his release of the ball is voluntary and intentional. If the fielder
has made the catch and drops the ball while in the act of making a throw
following the catch, the ball shall be adjudged to have been caught.
(Catch) Comment: A catch is legal if the ball is finally held by
any fielder, even though juggled, or held by another fielder
before it touches the ground.  Runners may leave their bases
the instant the first fielder touches the ball.  A fielder may
reach over a fence, railing, rope or other line of demarcation to
make a catch.  He may jump on top of a railing, or canvas that
may be in foul ground.  No interference should be allowed
when a fielder reaches over a fence, railing, rope or into a stand
to catch a ball. He does so at his own risk.
If a fielder, attempting a catch at the edge of the dugout, is
"held up" and kept from an apparent fall by a player or players
of either team and the catch is made, it shall be allowed.
The CATCHER is the fielder who takes his position back of the
home base.
The CATCHER'S BOX is that area within which the catcher shall
stand until the pitcher delivers the ball.
THE CLUB is a person or group of persons responsible for assem-
bling the team personnel, providing the playing field and required facili-
ties, and representing the team in relations with the league.

A COACH is a team member in uniform appointed by the manager
to perform such duties as the manager may designate, such as but not
limited to acting as base coach.
A DEAD BALL is a ball out of play because of a legally created
temporary suspension of play.
The DEFENSE (or DEFENSIVE) is the team, or any player of the
team, in the field.
A DOUBLE-HEADER is two regularly scheduled or rescheduled
games, played in immediate succession.
A DOUBLE PLAY is a play by the defense in which two offensive
players are put out as a result of continuous action, providing there is no
error between putouts.
(a) A force double play is one in which both putouts are force
plays.
(b) A reverse force double play is one in which the first out is a
force play and the second out is made on a runner for whom
the force is removed by reason of the first out. Examples of
reverse force plays: runner on first, one out; batter grounds
to first baseman, who steps on first base (one out) and throws
to second baseman or shortstop for the second out (a tag
play). Another example: bases loaded, none out; batter
grounds to third baseman, who steps on third base (one out);
then throws to catcher for the second out (tag play).
DUGOUT (See definition of BENCH)
A FAIR BALL is a batted ball that settles on fair ground between
home and first base, or between home and third base, or that is on or over
fair territory when bounding to the outfield past first or third base, or that
touches first, second or third base, or that first falls on fair territory on or
beyond first base or third base, or that, while on or over fair territory
touches the person of an umpire or player, or that, while over fair terri-
tory, passes out of the playing field in flight.
A fair fly shall be judged according to the relative position of the
ball and the foul line, including the foul pole, and not as to whether the
fielder is on fair or foul territory at the time he touches the ball.

(Fair Ball) Comment:  If a fly ball lands in the infield
between home and first base, or home and third base, and
then bounces to foul territory without touching a player or
umpire and before passing first or third base, it is a foul ball;
or if the ball settles on foul territory or is touched by a player
on foul territory, it is a foul ball. If a fly ball lands on or
beyond first or third base and then bounces to foul territory, it
is a fair hit.
A batted ball not touched by a fielder, which hits the pitcher's
rubber and rebounds into foul territory, between home and
first, or between home and third base is a foul ball.
Clubs, increasingly, are erecting tall foul poles at the fence line
with a wire netting extending along the side of the pole on fair
territory above the fence to enable the umpires more accurately
to judge fair and foul balls.
FAIR TERRITORY is that part of the playing field within, and
including the first base and third base lines, from home base to the bot-
tom of the playing field fence and perpendicularly upwards. All foul lines
are in fair territory.
A FIELDER is any defensive player.
FIELDER'S CHOICE is the act of a fielder who handles a fair
grounder and, instead of throwing to first base to put out the batter-run-
ner, throws to another base in an attempt to put out a preceding runner.
The term is also used by scorers (a) to account for the advance of the bat-
ter-runner who takes one or more extra bases when the fielder who han-
dles his safe hit attempts to put out a preceding runner; (b) to account for
the advance of a runner (other than by stolen base or error) while a
fielder is attempting to put out another runner; and (c) to account for the
advance of a runner made solely because of the defensive team's indiffer-
ence (undefended steal).
A FLY BALL is a batted ball that goes high in the air in flight.
A FORCE PLAY is a play in which a runner legally loses his right
to occupy a base by reason of the batter becoming a runner.
(Force Play) Comment: Confusion regarding this play is
removed by remembering that frequently the "force" situation

is removed during the play. Example: Man on first, one out,
ball hit sharply to first baseman who touches the bag and bat-
ter-runner is out. The force is removed at that moment and run-
ner advancing to second must be tagged. If there had been a
runner on third or second, and either of these runners scored
before the tag-out at second, the run counts. Had the first base-
man thrown to second and the ball then had been returned to
first, the play at second was a force out, making two outs, and
the return throw to first ahead of the runner would have made
three outs. In that case, no run would score.
Example: Not a force out. One out. Runner on first and third.
Batter flies out. Two out. Runner on third tags up and scores.
Runner on first tries to retouch before throw from fielder
reaches first baseman, but does not get back in time and is out.
Three outs. If, in umpire's judgment, the runner from third
touched home before the ball was held at first base, the run
counts.
A FORFEITED GAME is a game declared ended by the umpire-in-
chief in favor of the offended team by the score of 9 to 0, for violation of
the rules.
A FOUL BALL is a batted ball that settles on foul territory
between home and first base, or between home and third base, or that
bounds past first or third base on or over foul territory, or that first falls
on foul territory beyond first or third base, or that, while on or over foul
territory, touches the person of an umpire or player, or any object foreign
to the natural ground.
A foul fly shall be judged according to the relative position of the
ball and the foul line, including the foul pole, and not as to whether the
infielder is on foul or fair territory at the time he touches the ball.
(Foul Ball) Comment: A batted ball not touched by a fielder,
which hits the pitcher's rubber and rebounds into foul territory,
between home and first, or between home and third base is a
foul ball.
If a fly ball lands in the infield between home and first base, or
home and third base, and then bounces to foul territory without
touching a player or umpire and before passing first or third
base, it is a foul ball; or if the ball settles on foul territory or is

touched by a player on foul territory, it is a foul ball. If a fly
ball lands on or beyond first or third base and then bounces to
foul territory, it is a fair hit.
FOUL TERRITORY is that part of the playing field outside the
first and third base lines extended to the fence and perpendicularly
upwards.
A FOUL TIP is a batted ball that goes sharp and direct from the bat
to the catcher's hands and is legally caught. It is not a foul tip unless
caught and any foul tip that is caught is a strike, and the ball is in play. It
is not a catch if it is a rebound, unless the ball has first touched the
catcher's glove or hand.
A GROUND BALL is a batted ball that rolls or bounces close to
the ground.
The HOME TEAM is the team on whose grounds the game is
played, or if the game is played on neutral grounds, the home team shall
be designated by mutual agreement.
ILLEGAL (or ILLEGALLY) is contrary to these rules.
An ILLEGAL PITCH is (1) a pitch delivered to the batter when the
pitcher does not have his pivot foot in contact with the pitcher's plate; (2)
a quick return pitch.  An illegal pitch when runners are on base is a balk.
An INFIELDER is a fielder who occupies a position in the infield.
An INFIELD FLY is a fair fly ball (not including a line drive nor an
attempted bunt) which can be caught by an infielder with ordinary effort,
when first and second, or first, second and third bases are occupied,
before two are out.  The pitcher, catcher and any outfielder who stations
himself in the infield on the play shall be considered infielders for the
purpose of this rule.
When it seems apparent that a batted ball will be an Infield Fly, the
umpire shall immediately declare "Infield Fly" for the benefit of the run-
ners. If the ball is near the baselines, the umpire shall declare "Infield
Fly, if Fair." 
The ball is alive and runners may advance at the risk of the ball being
caught, or retouch and advance after the ball is touched, the same as on
any fly ball. If the hit becomes a foul ball, it is treated the same as any foul.

If a declared Infield Fly is allowed to fall untouched to the
ground, and bounces foul before passing first or third base, it is a foul
ball. If a declared Infield Fly falls untouched to the ground outside the
baseline, and bounces fair before passing first or third base, it is an
Infield Fly.
(Infield Fly) Comment: On the infield fly rule the umpire is to
rule whether the ball could ordinarily have been handled by an
infielder-not by some arbitrary limitation such as the grass, or
the base lines. The umpire must rule also that a ball is an
infield fly, even if handled by an outfielder, if, in the umpire's
judgment, the ball could have been as easily handled by an
infielder. The infield fly is in no sense to be considered an
appeal play. The umpire's judgment must govern, and the deci-
sion should be made immediately.
When an infield fly rule is called, runners may advance at their
own risk.  If on an infield fly rule, the infielder intentionally
drops a fair ball, the ball remains in play despite the provisions
of Rule 5.09(a)(12).  The infield fly rule takes precedence.
If interference is called during an Infield Fly, the ball remains
alive until it is determined whether the ball is fair or foul.  If
fair, both the runner who interfered with the fielder and the bat-
ter are out.  If foul, even if caught, the runner is out and the bat-
ter returns to bat.
IN FLIGHT describes a batted, thrown, or pitched ball which has
not yet touched the ground or some object other than a fielder.
IN JEOPARDY is a term indicating that the ball is in play and an
offensive player may be put out.
An INNING is that portion of a game within which the teams alter-
nate on offense and defense and in which there are three putouts for each
team. Each team's time at bat is a half-inning.
INTERFERENCE
(a) Offensive interference is an act by the team at bat which inter-
feres with, obstructs, impedes, hinders or confuses any fielder
attempting to make a play. 
(b) Defensive interference is an act by a fielder that hinders or pre-
vents a batter from hitting a pitch.

fielder.
(d) Spectator interference occurs when a spectator (or an object
thrown by the spectator) hinders a player's attempt to make a
play on a live ball, by going onto the playing field, or reaching
out of the stands and over the playing field.

ORDINARY EFFORT is the effort that a fielder of average skill at
a position in that league or classification of leagues should exhibit on a
play, with due consideration given to the condition of the field and
weather conditions.
(Ordinary Effort) Comment: This standard, called for several
times in the Official Scoring Rules (e.g., Rules 9.05(a)(3),
9.05(a)(4), 9.05(a)(6), 9.05(b)(3) (Base Hits); 9.08(b)
(Sacrifices); 9.12(a)(1) Comment, 9.12(d)(2) (Errors); and
9.13(a), 9.13(b) (Wild Pitches and Passed Balls) and in the
Official Baseball Rules (e.g., Definitions of Terms, Infield
Fly), is an objective standard in regard to any particular fielder.
In other words, even if a fielder makes his best effort, if that
effort falls short of what an average fielder at that position in
that league would have made in a situation, the official scorer
should charge that fielder with an error.
An OUT is one of the three required retirements of an offensive
team during its time at bat.
An OUTFIELDER is a fielder who occupies a position in the out-

base, is with such momentum that he loses contact with the base.
A PENALTY is the application of these rules following an illegal act.
The PERSON of a player or an umpire is any part of his body, his
clothing or his equipment.
A PITCH is a ball delivered to the batter by the pitcher.
(Pitch) Comment: All other deliveries of the ball by one player
to another are thrown balls.
A PITCHER is the fielder designated to deliver the pitch to the batter.
The pitcher's PIVOT FOOT is that foot which is in contact with the
pitcher's plate as he delivers the pitch.
"PLAY" is the umpire's order to start the game or to resume action
following any dead ball.

while holding the ball securely and firmly in his hand or glove; or touch-
ing a runner with the ball, or with his hand or glove holding the ball (not
including hanging laces alone), while holding the ball securely and
firmly in his hand or glove. It is not a tag, however, if simultaneously or
immediately following his touching a base or touching a runner, the
fielder drops the ball. In establishing the validity of the tag, the fielder
