Penalty For Use Of Illegal Bats

The bat rule adopted is for the safety of players.  It is a coach’s responsibility to ensure that the bats being used by their players conform to the bat rule and as such, offenses are considered a serious breach of rules.


First Offense – If the umpire discovers that the bat does not conform to Cooper City Optimist Baseball Rules and prior to a ball being put into play, the umpire will remove the bat from play and the player must then utilize a legal bat.  It shall not be grounds for declaring the batter out and/or ejection from the game.  If the umpire discovers that a bat has been used to put a ball in play and before the next legal pitch, the defensive team will have the choice of the result of play or the batter being called out and all runners returning to the base occupied before the pitch.


Second Offense – If a team is found in violation of this rule a second time (coming to the plate with an illegal bat – whether or not a ball is put into play), then the manager (or acting manager) will be ejected in addition to the First Offense penalty.
