CA District 52 is located in Northern California and covers most of the San Francisco Peninsula (except the city of San Francisco) and contains member leagues from San Mateo County and Northern Santa Clara County.  San Mateo Little League American is a member of District 52.

Following the completion of our regular season (February to early June), we select postseason All-Star teams to represent us at the District level (and hopefully beyond) during the Summer.  District 52 hosts a postseason tournament for our teams at 5 different age group levels (8-10, 9-11, 10-12, 13, and 14).  The winners of the District Tournament for each age group advance to the California Section 3 tournament.  The winners of the Section 3 tournament advance to the Northern California tournament.  The road ends at NorCal’s for all ages, except 10-12’s, also known as Majors.

For Majors, the winner of the Northern California tournament advances to the Western Regional in San Bernardino, CA.  The Western Regional brings together the champions from Arizona, Hawaii, Nevada, Northern California, Southern California, and Utah who compete for the right to advance to the Little League World Series in South Williamsport, Pennsylvania, which is broadcast annually to a national television audience on ESPN and ABC.
