Welcome Umpires to another great season of Little League baseball in Boulder, Colorado. Our spring season begins on Saturday, April 4th and ends with the last week of summer play in  August. We will once again need staffing to cover games at North Boulder Park, Iris Fields, Tom Watson Park, and Centennial Middle School, all in north Boulder. If you are a returning umpire, please log into your account to verify that you are a registered official and update your contact information. If you are new to the league and would like to become a member of our umpire crew, please select Register Online on the left menu bar and go to Umpire Registration.

Umpire Orientation and Training is TBD. If you have any questions, please contact Jake for more info at
