Umpire Rule Reference Sheet
(All Divisions)

Time Limit & Tiebreaker

  • No new inning after 90 min.

  • Start times are 6:30pm and 8:15pm (NO grace period)

  • If the game is tied after 9 innings the game will continue using the “International Tiebreaker Rule”.  Under this rule, each team starts the inning with the player who completed the last official at bat, as a base runner on second base and one out. Each subsequent inning will start the same until a winner has been determined.

  • Tiebreaker is not in effect during the playoffs. Games are played until completion regardless of time limits.

Number of Players

  • Teams may start the game with a min of 8 players, max 20 players.  When playing with eight (8) or nine (9) players, the 9th and/or 10th spots in the batting lineup are NOT automatic outs.  

  • Once the game has commenced and a team has batted through their order, players may only be added to the lineup to a maximum of ten (10). Subsequent players added to the line-up will be by substitution only.

  • A player who is deleted from the line-up due to injury during a game is not an out (deleted players may not re-enter the game).

Courtesy Runners

  • 3 per game (does not have to be the last out)

  • No injury runners from the fence

Exception: IF a player is injured during the course of the game such that he cannot make it to 1st and IF the game would be forfeit without said player remaining in the lineup, a runner from the screen may be allowed at the discretion of the umpire.


  • All Divisions will follow a 6ft to unlimited pitch range.
