The house rules have been put into place to help keep everyone safe, to keep the games fair and to make sure everyone is having a great time.
The umpires are paid to enforce the rules, but remember, they are human and will make mistakes from time to time. The ruling by the umpire on the field will stand. Any discussion on a call is only allowed after the game. Any abusive language will not be tolerated by the league and may result in a player being ejected from the game/park.
