Umpire Information

Welcome to the Umpires page for Los Gatos Little League

 Los Gatos Little League depends on adult volunteer and youth umpires to officiate baseball games.  For active players, umpiring can be a great way to enhance your understanding of the rules of baseball and how they are applied in game situations.  It is also a fun way to stay involved in baseball if you’re no longer playing.  The League’s umpires come from three categories:

1.     District Umpires:  Volunteer umpires that have been officially certified and/or trained by Little League International.

2.     Adult Umpires:  Persons over 21 who have successfully completed an umpire training clinic such as the Western Region Outreach Umpire Clinic (see below for more information) or equivalent.  Adult umpires perform without reimbursement.

3.     Youth Umpires:  Full or part time students, 20 years old or younger who have completed the umpire training conducted by Los Gatos Little League or equivalent.  Youth umpires do get compensated for their time or receive community service hours/credits.  Youth umpires may umpire AA, AAA, and Major league baseball games, with the following age restrictions*:

•    AA: 11 years old, as of January 1st 2024

•    AAA: 13 years old, as of January 1st 2024

•    Majors: 15 years old, as of January 1st 2024

Youth Umpire


The 2024 Los Gatos Little League season is just around the corner and the League needs experienced and new youth umpires for our AA, AAA and Majors division baseball games.  In order for the youth program to be successful, we need responsible youths who are interested in giving back to the community.

For both new and returning umpires, we encourage everyone to attend the youth training clinic . This is the best way to learn about how to learn the basics of becoming an umpire, the rules of baseball, and the on-field mechanics of officiating games.  Dates, times and locations for the clinics can be found below as details are confirmed. 

If you are interested in becoming a youth umpire and have not umpired in District 12 or Los Gatos previously, please complete the following form. 

NOTE: returning umpires do not need to fill out this form as you are still in our system.

 Los Gatos Little League is very proud of its youth umpire program.  We believe it is an outstanding way to develop the character, courage, and leadership of our youth.  If you have any questions please contact the Los Gatos Little League Umpire-In-Chief, Nick Bonacorsi at [email protected]


Youth Umpire Clinic -FEBRUARY 10th, 2024

The annual District 12 Youth Clinic is scheduled for Saturday, February 10th at Baggerly Field. All Umpires are required to attend our mandatory trainings prior to working any games. Umpires are considered independent contractors based on their expertise in applying the rules of Little League Baseball.

Led by our own District 12 umpire (and plate umpire for the 2012 Little League World Series Championship Game) Dan Campagnolo, this clinic discusses the mechanics of Little League and is open to all returning and new youth umpires.  Lunch and drinks will be provided. 

Adult Umpires


It is a little-known fact that virtually all adult umpires used for Little League baseball in Los Gatos (and everywhere around the world) are volunteers.  Los Gatos Little League and District 12 staff umpires will provide each adult umpire with thorough training and direction in advance of your first game.  

Umpires are great role models for the children and a great way to volunteer locally in the community, so please sign up today to partner with our youth umpires!

We always need eager adult umpires, especially for our Juniors and Majors games, where game management is of the utmost importance due to the higher level of competition.  Our adult umpires love the thrill of having “the best seat in the house” to watch some great baseball, and they enjoy the challenge of making the right call…quickly, confidently and decisively.

If you are interested in becoming an adult umpire and either have experience or have not done so in the past, please complete an Adult Umpire Application.  You must also complete a Little League International approved Volunteer Application and pass a background check. 

All umpires must attend mandatory training prior to their first game.

We are fortunate to have multiple opportunities for training across District 12 locations this year.
