JKUmp,

I feel your pain! For me, I'd call the coaches of each team to the plate during the break between innings and ask them to take care of the situation if that person is a fan of their team, which should do it.

If the coaches say the fan isn't a follower of their team, I'd contact the person in charge of the facility to call for police. In some states, it's against the law to use foul language and make obscene gestures.

If the coaches don't take care of the fan, there are things as the plate ump you can do:

1) Strike zone for the fans team when at bat becomes larger and larger. While on defense it becomes smaller and smaller. Just lean over the catcher and tell him to silence the fan and things will get back to normal. I'd just say my concentration is being interupted by the fan and I can't focus on the pitch. By the time you toss the players for protesting the strike zone, you've got a forfiet. Game over! I know all of this is not ethical, but drastic times call for drastic measurers!
