Umpire Sign-Ups


Umpiring can be a challenging and rewarding experience. It's a great part-time summer job for youth. For adults, it's a way to stay involved in the game you love and also make some extra spending money.

If you are 12 years of age or older (as of May 1, 2019) and are interested in umpiring, please review the information below.
