Fall 2010 Co-ed Softball
One Pitch Softball Rules

The rules for a One-Pitch Softball Tourney are different than a regular softball tourney.


A. Ten (10) players (5 women, 5 men) shall constitute a team can have up to 12 players maximum. Men and women must be listed alternately in the batting order. An even number of men & women players must be playing for each team at all times.

B. A game cannot begin without at least eight (8) players (4 women, 4 men) per team. Additional players may enter the line up upon their arrival whenever play is dead. Additional players will automatically be put at the end of the batting order, alternating men and women.


A. Metal spiked or metal-cleated shoes are illegal.

B. Official Balls used for tournament: Each team is required to bring a men’s ASA approved 12” softball and a women’s ASA approved 11” softball. Both teams are required to have their official game balls at all games they play. The batting team will use their own balls. Each team is responsible for getting their balls back from the umpire after each inning.

C. Baseball bats are illegal. Teams are required to supply their own bats provided they are factory marked as an “Official Softball” bat. All bats used during games must be approved by the diamond’s home plate umpire before play starts.


A. Each batter gets one pitch to swing at and hit. If the batter fouls it, flies out, swings and misses or is thrown out, they are OUT! If the batter does not swing and the umpire calls a strike, the batter is OUT! If the pitch is considered a “ball” and the batter does not swing, they walk.

B. Each team is allowed only one (1) over-the-fence homerun per game. After that one homerun has been obtained, any other over-the-fence homeruns are considered an automatic OUT!

C. A batter is immediately out if they attempt to bunt. The ball is dead and the runner(s) may not advance. (It is considered a bunt anytime the batter holds the bat still over the plate and allows the ball to hit the bat, no matter how the batter got the bat to that position.)

D. Substitutions/Player Re-Entry – Any of the starting players and substitutes may be substituted and re-entered as many times as a team wishes, provided players occupy the same batting positions whenever in the lineup. The starting player and the substitute(s) may not be in the lineup at the same time.

E. Base Stealing

1. Under no condition is a base-runner permitted to steal a base. They may leave their
base when a pitched ball has reached or passes homeplate.

2. When a base-runner fails to maintain contact with the base to which they are entitled
until a legally pitched ball has reached homeplate, the ball is dead, no pitch is
declared and the base-runner is OUT!

III. PLAY (cont.)

F. Baserunning

1. When a defensive player has the ball and is waiting for the runner and the runner remains on their feet and deliberately crashes into the defensive player, the runner is declared out.

NOTE: If the act is deemed flagrant, the offender shall be ejected.

2. Dislodged Base – If a runner dislodges a base from its proper position, neither they nor the succeeding runners in the same series of plays are required to follow a base unreasonably out of position.

3. Overslide/Overrun – A batter may overrun or overslide first base and return directly to the base without liability to be tagged out. The runner may be tagged out when there is an attempt or movement towards second base. Simply turning, either to the left or to the right is not an attempt to go to second. Whether a runner simply turns or attempts to advance to second is an umpire’s judgment.

G. No batter is automatically safe on a hit or error. They must run it out and make it to the base safely.

H. Overthrows – On thrown balls that go out of play (dead ball territory), all runners will be awarded two bases governed by the positions of the runners when the ball left the fielder’s hand. Runners may return to touch a missed base.

I. The ball becomes dead after each pitch and completed play. Pick-off attempts by the catcher are NOT ALLOWED.

J. A batter may be ejected from a game and an out charged to their team if they let the bat slip from their hands more than once or throws their bat intentionally.

K. When checking the ball after each play, the person returning the ball to the pitcher MUST RETURN THE BALL IMMEDIATELY.


Teams must submit a lineup, have all players in the dugout and be ready to play at least five (5) minutes before the scheduled time of the game. If a team fails to have the minimum number of players present at the scheduled location within 5 minutes of the scheduled time, the game will be declared forfeited to the team ready to play.

Each team must keep their own score.

A. The “home” and “visiting” teams will be determined by a coin toss prior to the beginning of the game.

B. A game will consist of seven (7) innings. During tournament play, a time allotment of thirty five (35) minutes is set to complete the seven (7) innings. NO INNING CAN BEGIN after the 35 minute limit. A game is not to be suspended until an inning is completed, regardless of the time limit. When the time limit gets close, the umpire will determine if a full inning can be completed within the 40 minute time period. If the umpire determines a full inning (giving the home team last ups) cannot be completed before the 35 minute time limit, the umpire has the authority to call the game even if there is time remaining in play time. All innings MUST end with the “home” team up last.

C. Five (5) complete innings (4 ½ innings if the home team is ahead) constitutes a game, and the director will declare the team leading the winner in the following conditions:

1. The game passes the thirty five (35) minute time allotment during tournament play and the inning has been completed.

2. Inclement weather conditions during tournament and championship play – If weather
conditions necessitate calling the game in the middle of an inning, the score of the last
completed inning will stand and the game will be considered official.

D. Tie Games

1. Tournament Play – If the score is tied at the end of seven (7) innings and the time allotment has run out, the team who was ahead in the last completed inning will be declared the winner. If the teams were tied at the end of that inning, the previous inning will determine the winner and so on.

2. Championship Playoff games shall be seven (7) innings long and must be completed unless halted by the “Run Ahead Rule”. (Tie games will continue into extra innings until the tie is broken and the “home” team has had last ups.)

3. “Run Ahead Rule” – 15 after 5 innings or 4 ½ innings if the home team is ahead. Complete innings must be played unless the home team scored the run ahead limit while at bat. When the visiting team reaches the limit in the top half of the inning, the home team must have their opportunity to bat in the bottom half of the inning.

Slowpitch League Rules


A. Unless modified by this set of rules, all games of the league shall be
played in accordance with the current slow pitch rules adopted by the
Amateur Softball Association (ASA).

B. The number of players to start and continue a game shall be as
follows: All league games may start and/or be played with a minimum
of 8 players, only if the ninth and tenth eligible player(s) are not
available. If a ninth and tenth player(s) arrive after the start of a
game, he/she bats in the ninth and tenth position. Teams will not
receive outs for these missing positions. If a game is started with
eleven players it must end with 11 players if substitutes are available.

C. Additional Hitter(s) Rule (optional in ALL Leagues) Teams have
the option at the start of the game to bat 12 players, but defensively
play 10. A team may insert an additional hitter(s) into its line-up at
the start of a game only. The batting order must remain constant,
however, any 10 of the 12 players can take defensive position
throughout the game. All 12 players shall be subject to the re-entry

D. Courtesy Runners: (Only for Individuals with Physical/Health
Related Issues or Players Injured During a Game and no
Substitutes are Available): a Courtesy Runner at the first dead ball
may replace any batter/base runner on a base after they reach base. The
Courtesy Runner is defined as “the last completed turn at bat not
currently on base” (Co-Ed) – “the last completed turn at bat of the same
sex not currently on base”. If it should happen in the first inning and no
one has been retired or scored, it will be filled by the last spot in the
batting order. Players with Physical/Health Related Issues,
requesting Courtesy Runners, must report to the umpire, as well
as, gain approval from the opposing manager, prior to entering
the game; same process and approval procedure for players
injured during a game.

E. Rule 6 – Pitching Regulation (Slow Pitch)

(Safety) – A imaginary line from the front edge of each side of the
pitching rubber will be drawn back (6)six feet to form a rectangular
box. Since the pitching rubber is (50) fifty feet from the home plate,
the imaginary box will extend back to (56) fifty-six feet, and the
pitcher will be allowed to pitch anywhere inside of that box. The
pitcher must have one foot touching the box to begin pitching. All
other rules regarding pitching will still be in force.

F. Rule 8. Sec. 4G – Stealing (Men’s Slow Pitch)
(This rule does not apply to any of the men’s , women’s or
Co-ed softball leagues.

G. Any team leading by 10 or more runs after 5 innings (4 &1/2 if the home
team is ahead) or any complete inning thereafter will be declared the
winner and the game will be complete.

H. Home Run Rules (an untouched fair ball over the fence) One-Up
in affect for all leagues

1. Men’s ‘C’ – (5) home runs with one-up after fifth (5th) home run.
2. Men’s ‘C/D’ – (4) home runs with one-up after fourth (4th) home run.
3. Men’s ‘D’ – (3) home runs with one-up after third (3rd) home run.
4. Co-ed and Women’s (all divisions) - (5) home runs with one-up
after fifth (5th) home run.

One-Up Rule: Once both teams reach their home run limits, the teams
are allowed one additional home run. As long as both teams keep
matching the limit or equal number of home runs, teams may continue
to hit additional home run(s). If one team reaches the limit and goes
over the limit before the other team reaches their limit, the home runs
become an out. The one-up rule is in affect for all innings.
Teams are responsible for retrieving or providing back-up balls,
as specified in these rules, for home runs hit over the fence. If a
player hits a over the limit, successive untouched ball over the fence,
the batter will be ruled out.

I. Base awards must be touched in legal order.
Exception: All Men’s Slow Pitch. (This does not apply to Co-Ed and
women’s play). On any fair-batted ball hit over the fence for a
home run, or a four base award, the batter and any runners are
credited with a score. The batter and any runners can go directly
to the dugout. This would eliminate any runner appeal play.

J. Use of double first base and batter-runners inappropriately
touching only the white portion of the base.
“The batter-runner is out when there is a play being made at first
base and the batter-runner touches only the white portion provided the
defense appeals prior to the batter –runner returning to touch the white
or colored base.”

K. A runner shall be declared out when a defensive player has the ball and
the runner remains on his or her feet and initiates contact with the
defensive player. The runner shall be ejected from the game (if, in the
judgment of the umpire, the contact is flagrant).

L. A runner shall be declared safe (obstruction shall be called) when a
defensive player initiates contact by blocking a base or home plate and
the defensive player does not possess the ball. A defensive player must
grant unimpeded access to a base when he is not in possession of the
ball or in the act of fielding a batted ball.

M. A player shall be officially in the game when his/her name has been
entered on the Official Score Sheet (home team is official) or has been
announced. When preparing the team’s batting order for the game, and
prior to exchanging line-ups with the opposition, you must use the
following format for listing player’s names.
Always first initial and last name in full. When more than 1 player has the same last name, please list full first and last name of these players.

A. A team shall consist of 5 men and 5 women and 5 of each sex on the
field. If a team is playing with (8) players, there must be 4 of each
sex on the field; (9) players, there must be 5 of one sex and 4 of the
other sex on the field.

B. Additional Hitter(s) Rule (optional in the Co-Ed Leagues)
A team may insert 2 additional hitters, one of each sex, into its line-up
at the start of a game only. The batting order must remain constant;
however, any 10 (5 male and 5 female) of the 12 players can take a
defensive position throughout the game. If the game is started with 12
players, it must end with 12 players if substitutes are available. All 12
players shall be subject to the re-entry rule.

C. In all Reverse Co-Ed divisions, the men shall hit a 12-inch
circumference softball and the women shall hit an 11-inch
circumference softball.

1. The home team will provide one "new" 12-inch ball and one
"new" 11-inch ball.

2. The offensive team MUST provide a first base coach. The first
base coach will be responsible for giving the defensive pitcher
the proper size ball for the batter. For example, if a team has a
male batter, the first base coach will provide the 12-inch ball to
the pitcher. As soon as the play has ended and the umpire calls
time out, the 12-inch ball would then be replaced with the 11-
inch ball for the female batter by exchanging balls between the
first base coach and pitcher.

3. If a ball is hit out of play and cannot be recovered quickly, the
team that is at bat must furnish as many additional league specified
balls as needed to complete their turn at bat.

4. If the incorrect ball is pitched to a batter the following
enforcements will apply.
Female batter pitched the 12-inch ball:

a. If the wrong ball is used, the manager of the offensive
team has the option of taking the result of the play or
having the last batter re-bat and assume the ball and
strike count prior to the wrong ball being discovered.

Male batter pitched the 11-inch ball:

a. batter-runner safely reaches first base or beyond, the
play will stand.
b. batter-runner fails to safely reach first base as the result
of a fly out, ground out, foul out, etc., the play will stand;
no replays will be granted.

Male or female batters:

a. Upon the discovery that an incorrect ball has been used,
the umpire shall rectify the situation by placing the
appropriate ball in play; the count from the previous pitch
is official regardless of whether the batter was a male or

Example: Female batter
_ First pitch is a strike,
_ Catcher discovers that a 12-inch ball was pitched,
_ Umpire replaces the 12-inch ball with the proper
ball prior to the next pitch,
_ The count reflects the prior pitch, which should
indicate 1 ball, 2 strikes.

D. The offensive line-up may begin with either a man or a woman,
thereafter the sexes shall alternate. EXCEPTION: If a team is playing
with 9 players, the offensive line-up must begin with sex which has 5
players and there will be a repetition of sex in the line-up.

E. Positions in the field may be distributed as the coach/captain desires.
While positions in the field may be changed at any time, the
male/female order of the starting line-up must be maintained.

F. Men shall assume the batting stance opposite to that which they would
normally use in a softball game. Opposite-handed means: If the
individual fields with the glove on the left hand and throws right-handed
normally, he is supposed to bat left-handed and vice-versa. If
the opposing manager feels that any male is not batting opposite
handed or on their weaker side as required, he may require the batter
to switch his batting stance anytime. The manager can reverse this
decision anytime during the game and once the decision is reversed, it
will be final.

Example: If a left-handed male batter hits a home run right-
handed, the next time at the opposing manager requests that he bat
left-handed. Left-handed, he bats another home run. The opposing
manager has one last chance at his next at-bat to decide with which
hand the batter shall bat. At this point, the decision is final.

G. Walk Rule:
The following walk rule will be used in this division only: When a male
batter is walked intentionally or unintentionally, the male batter is
awarded first and second base and the following female batter must

Exception: With two outs, the female batter has the option
to walk or bat.
In all other Co-Ed Divisions, female batters do not have the option of
walking if the preceding male batter is walked. The pitcher must pitch
to all batters unless the pitcher declares an intentional base on balls.


A. In all leagues, when a batter enters the batter's box, he/she will have the
count of one ball and one strike. After the batter has reached two strikes,
he/she will be declared out when he/she hits a second foul ball. (If the foul
fly ball is caught, runners may tag and advance at their own risk.)

B. Time Limit: There will be a 65-minute time limit for all games. The time
limit begins with the first pitch. No new inning may begin after the time
limit has been reached. An inning that has begun will be completed, and if
the time limit has been reached, at that point the game will end with the
team ahead declared the winner. For time limit purposes, the new
inning begins when the 3rd out occurs.

C. Tie Game: If the game is tied after the Time Limit has been reached, the
game will remain a tie. No new inning will start after the time limit. For
purposes of league standings, teams will receive two (2) points for a win, one
(1) point for a tie, zero (0) for a loss and (-1) for a forfeit. Post
Post-Season related tournaments: The ‘one-pitch’ format will be used to
decide tie games.

The following policies and procedures will apply:

No new inning shall start after 10:30 p.m. and there is an absolute curfew of 10:45 p.m. All play stops at this time. If a game is stopped due to the
curfew or darkness in the middle of an inning, the game reverts back to the
last full complete inning.
D. There will be a 10 minute grace period for all 6 p.m. and 6:15 p.m. weekday games. However, the official will start the time limit clock at the scheduled game time. Example, for games scheduled to start at 6 p.m. the time limit rule will be 7:05 p.m. If part of the 65-minute game time is lost due to weather (rain, lightning and/or thunder), maintenance issues, or and injury to a player that “lost” time counts towards the official 65-minute game time limit, just as the 10-minute grace period does for games that are scheduled to start at 6:00 PM.

For example: If a game is stopped due to weather and at least 30 minutes of
playing time in the game remains then it should be continued from the point
stopped. If less than 30 minutes remains the game should be postponed and
continued from the stopping point at a later date.

For Sunday league games and weekend make-up games, the 10
minute grace period will not be in effect.

Forfeited Game: A team forfeits a game when it fails to have the minimum
number of players to start a game or maintain the minimum number of
eligible players to continue playing. Teams participating in Doubleheaders will
forfeit each game separately. Teams that forfeit the first game of the
doubleheader due to insufficient number of players, must begin the second
game of the Doubleheader as soon as they have the minimum number of
eligible players present, but no later than the scheduled starting time for the
second game.

VI.  Equipment:

The official game ball for all Men's, Women's, and
Reverse Co-Ed Leagues will be furnished by the Recreation
Department and to all teams. The official ball for the league play will
be as follows:

Men’s - WT12RF 80 ASA Leather Cover, .44 Cor/375lbs. compression
Women’s – WT-11 RF 80 ASA Leather Cover, .44Cor/375

No other softballs are acceptable other than .44 Cor/375lbs.
compression balls. The Home Team shall furnish 2 new balls to start
the game. If additional balls are needed, the team at bat shall furnish
as many additional playable balls as needed to complete the game.
The 2 new balls, 1 each, should be introduced at the top half and
bottom half of the first inning. The balance of the game should always
be played with the best ball as judged by the Umpire.

H. BATS: The official bat for the adult softball program must meet all the
ASA specifications and the requirements of Rule 3, Section 1, and:
1. must bear either the ASA approved 2000 certification mark or
the ASA 2004 Certification mark as shown below, and must
not be listed on an ASA non approved bat list, or

2. must be included on a list of approved bat models published by the
ASA; or

3. must, in the sole opinion and discretion of the umpire, have been
manufactured prior to 2000 and, if tested, would comply with the ASA
bat performance standards then in effect.

Beginning January 1, 2004, all bats must pass the ASA bat standard.
All bats having the 2004 certification mark will be allowed. Bats that
have the 2000 certification mark will not be allowed unless they are
listed on an approved bat list on the ASA website. For convenience, the
ASA website has a listing of bats that do not pass the ASA 2004 bat
