Bellevue Thunderbird Umpire Program

Bellevue Thunderbird Little League supports a robust umpire program that includes a Junior Umpire program, plus a corps of volunteer adult umpires and umpire consultants. We provide extensive training, close supervision, and a supportive environment. Thunderbird provides umpires for both baseball and softball.

  • Thunderbird provides training as well as access to District 9 training resources. All training is free.
  • Thunderbird provides umpire uniform shirts and hats.
  • Thunderbird provides all necessary umpire equipment.
  • Thunderbird provides a self-scheduling system so that you decide when you wish to help out.

The Junior Umpire Program

Our Junior Umpire program comprises boys and girls aged 12 and older who have experience playing baseball, softball or umpiring, and who have a lot of self-confidence and enjoy the sport. In their first year, junior umpires umpire at the AAA level (9 and 10 year olds), then, as skills and experience grow, they move on to umpire at the Coast and Majors levels. Junior umpires qualify for the Bellevue Thunderbird Youth Scholarship Program.

Adult Umpires and Coordinators

To support our Junior Umpire program, we need parent participation. We need our League parents to help out in a number of ways. We need adults to volunteer as umpires, of course, but we also need parents to help as team-level and division-level umpire coordinators. Having adult umpires is extremely important and we encourage all of our Thunderbird parents to consider being involved.

Note to employees of Microsoft and Alaska Airlines. Both of these corporations offer matching gifts on a dollar-per-hour basis for volunteer hours that employees work for nonprofit organizations. Bellevue Thunderbird Little League is a 501(c)(3) charitable organization and is eligible to receive contributions from Microsoft and Alaska Airlines for every hour that their employees contribute. Please contact us if you have questions about these programs.

How do I schedule myself as a Junior Umpire to work games?

Once you have registered as a Junior Umpire in our system (Bonzi) and the League runs your background check and confirms you, you have access to self-assign to available games. It's very easy, follow these steps:

1. Log into the member account used to register you as an umpire (typically a parent's account, but sometimes a youth umpire's account). This can be done from our homepage,, using the "Member Login" link towards the upper right corner.

2. This will take you to a page showing all family accounts associated with the member account. The Junior Umpire, once confirmed by the League, should have a button next to his or her name labeled "Official Management". Click on this, it will take you into the scheduling system.

3. You will arrive on a page called "My Game Assignments". If you have not self-assigned to any games yet, there will not be any information. Click on the tab titled "Self Assign Games". This will show you all games with open umpire slots which you are eligible to sign up for.

4. Click on "Assign me to this game" for a game that has a date, time and location that works for you. A drop-down box will appear showing you available positions, typically "Plate Umpire" and "Field Umpire". Choose one, and then click "Complete My Assignment".

6. That's it! Add other games, or log out. And remember, be careful with your calendar and be responsible with your obligation to show up at games you've scheduled. It is very hard on the League and the teams when an umpire doesn't show up or cancels at the last minute. Thank you!

Contacting Team Managers before a game

We suggest you let team managers know about you being scheduled to umpire their game, so they can let you know if there are any changes to the game schedule.
