Bat Protest Procedure
Teams wishing to protest the use of an illegal bat must notify the umpire before the next batter enters the batter's box. Once the first pitch to the next batter has been thrown, the protest will be considered invalid.
Result of Successful Protest
A successful protest will result in the automatic ejection of the player committing the infraction and the manager of the infracting team. The protesting team can then choose to accept an automatic out or the result of the play.
Non-Team Related Occurrences
Players participating in USA Baseball camps or individual based identification events that are found to have committed an infraction will have their participation reviewed by the operating staff and may face expulsion from the event.
