Co-ed Softball Rules

ASA Adult Co-Ed Softball Rules

  1. Players and Positions

    • A team is expected to field ten players for each game. Teams must have at least half of the players in the field be females. The batting order is required to alternate between male and female hitters. When in the field, there must be at least two females playing outfield positions and three females slotted for the infield.

    Co-ed Game-play

    1. All players MUST wear shoes. Soles may either be smooth or have soft or hard rubber cleats. Shoes having metal cleats are NOT allowed.Some teams like to intentionally walk certain batters as part of their strategy, but this could backfire in co-ed play. If a team walks a male batter, then the batter automatically goes all the way to second base rather than first as in regular softball leagues. Also, if there are two outs, the following female batter has the option of walking or hitting. This rule was instituted to even up play and prevent a team from only pitching to female players.Let’s have fun rule:In the name of playing the game and making sure that the players / teams have fun the coaches may make minor changes to the rules if both coaches agree and the intent of the Softball Rules are followed. (For example: A coach may choose to allow another team to use an unregistered player, a team does not have enough players within the five minute grace period, or a team doesn’t have enough guys/girls).

Teams must have eight (8) eligible players in the team area in order to start the game. When a ninth and/or tenth player arrives they will be placed in the last batting spot in the order. If additional players arrive prior to the first batter entering the batters box for their second time at bat the additional players may be added if the umpire is notified. Teams may bat as many players as they wish. If a team has elected to bat all players present at the start of the game they will be permitted to add any player arriving after the start of the game to the bottom of the lineup. The manager must let the umpire and opposing team know when you add anyone to the lineup.

      It will be the responsibility for the ejected player’s team to remove the player as directed by the umpire in the time requested. Failure to do so will result in the game being terminated and a forfeit issued to the offending team.


      Over the years the language that some players have used has become more and more vulgar and inappropriate for the setting that we conduct this program. Please advise your players that this type of behavior will no longer be tolerated by ComePlayDetroit. Outbursts using vulgar language (The Four Letter Words, etc.) will subject that player to ejection.


      If a ball goes into the parking lot, the rule is that the play is DEAD, and that it is the umpire’s discretion to determine where that player should go.


      In the name of playing the game and making sure that the players / teams have fun the coaches may make minor changes to the rules if both coaches agree and the intent of the Softball Rules are followed. (For example: A coach may choose to allow another team to use an unregistered player, or a team does not have enough players within the five minute grace period)
