All equipment shall be kept in the dug-outs during the game. Managers should have their players, when in uniform, keep their shirts tucked in and in general look like a ball player to be proud of. This includes the team bat-boy. Any player warming up a pitcher must have on a helmet. This applies for both practices and games.
Managers are to make sure a catcher has on a protective cup.
If he does not, he will be prevented from catching until he is wearing one. Teams must have at least eight players to start a game and must maintain at least eight players at all times during the game. Failure to do so results in forfeiture. In all leagues, a vacant ninth batting position will be an automatic out. A vacant tenth batting position will not be counted as an out.
