The umpire coordinator can be reached at
To register as an umpire, please email the Umpire Coordinator with the following information:
Cell Phone number:
Date of Birth:
Note that umpires 17 years of age or older are required to submit a CORI form, a Little League Volunteer form, along with a photocopy of your driver's license or other state issued photo ID. This process is required once per calendar year that you umpire for ABYB. Please see the Hey Coach! page to access the forms and details on submitting the information.
New Umpire Trainees:
New umpire training for Spring 2019 will be held on Thursday, April 11th, at 6pm in the Boxborough Library.
New umpires must attend, and existing umpires who would like a refresher can attend as well.
- For Minor A & Majors, umpires are scheduled by the ABYB Umpire Coordinator. Umpires will receive notification emails for each game they are assigned. If a game is rained out or otherwise re-scheduled, the original umpires are responsible for umpiring the make-up game. Coaches will receive contact info for the umpires, and need to be sure to inform the umpires of the make-up game date/time once they have cleared it with the ABYB Field Coordinator and/or Webmaster. If the original umpires are not available for the make-up, they are responsible for finding subs using the process outlined to them by the ABYB Umpire Coordinator.
- For Babe Ruth, umpires are scheduled by ArbiterSports. The ABYB Babe Ruth Coordinator will work with the local umpire assigner from Arbiter to get game schedules loaded into the ArbiterSports web site. Umpires for Babe Ruth will self-assign themselves to games on ArbiterSports. Babe Ruth coaches will receive a login account on the ArbiterSports web site where they can get umpire contact information to use in the event of a rain out or for other re-scheduling needs.
