District 57 Challenger Program 

The Little League Challenger Program is a program for mentally and physically challenged youth, helping them to enjoy the full benefits of Little League participation in an athletic environment structured to their abilities. More information about the Challenger Program is located HERE.

District 57 has several Challenger teams throughout the district. Teams meet each Sunday afternoon at the Dublin Sports Grounds to play games from March through June. In addition, District 57 sponsors the Annual Western Regional Challenger Jamboree each Memorial Day weekend, with teams from around the Bay Area and the state attending.

 If you are interested in participating in the Challenger Program and don't know which league you are part of or where to start, contact our District 57 Challenger Director, Mike Muranaka at  [email protected]
