NOTE: If the infraction is discovered before the next player enters the batter's box following the turn at bat of the player who used an illegal bat:
(1) The manager of the defense may advise the plate umpire of a decision to decline the penalty and accept the play. Such election shall be made immediately at the end of the play.
(2) For the first violation, the offensive team will lose one eligible adult base coach for the duration of the game.
A.R.—Any of the three adults in the dugout may be used as the one adult base coach at any time during the duration of the game. (that means only one adult base coach is allowed regardless of how many adults are present at the game or in the dugout)
(3) For the second violation, the manager of the team will be ejected from the game. Any subsequent violation will result in the newly designated manager being ejected. (a one game suspension also occurs and you will only be able to have 1 adult base coach the next game. If 2 are ejected, you will have no adult base coaches)
A.R.—When an illegal bat is discovered, it MUST be removed from the game at that point.
