If a game is tied after the time limit, the international rule will apply. The last batter out from the previous inning will be put on 2nd base with one out. The proper batter will come to bat.
  12. Rainouts will be played the following Tuesday. If a storm comes up during a game, the game will be postponed until the storm is over (30 minutes after the last lightning strike or thunder clap) if field is still playable or the following Tuesday.

  14. Each team will umpire their own games. Teams will provide a home plate umpire when their team is at bat. The umpire can be anyone on the team. The Park Staff will honor any rulings on the field from the umpires. If umpires feel it is necessary, they may ask individuals to leave the game and premises due to inappropriate behavior.
