  • We will be using SPO Hot Dot Classic Plus balls (SPO12HDSY) for all of our leagues.
  • Each team will be given 2 balls at the start of the season, teams are to supply their own if more balls are needed.
  • At the beginning of the game each team will give the umpire 1 ball to use during the game. The umpire will return the ball at the end of the game.  The team listed first on the schedule will have to provide a new (or reasonably new) ball.  The team listed 2nd on the schedule will provide a used but in good shape ball.


  • All bats must be USSSA certified and have the USSSA 1.20 BPF thumbprint on the taper of the bat.  If you are buying a new bat make sure it has the USSSA 1.20 BPF thumbprint
  • We also allow the older bats with the ASA 2004 stamp.
  • Any other bats will not be permitted.
  • If a player steps into the batters box with an illegal bat the opposing team must notify the umpire at that time.  The umpire will inspect the bat and if ti is deemed illegal the batter will receive an out.  Repeat offenders will be ejected from the game and receive further suspensions.
