Welcome to San Mateo Little League American

Welcome to San Mateo Little League American! For over 55 years we have brought the great game of baseball to the youth of the San Mateo and Burlingame. Every year we have approximately 600 players swinging bats, throwing & catching balls, making new friends, seeing old friends and keeping Trinta Park filled with the neighbors in our communities - enjoying one of our nation's favorite pastimes. We are proud of the tradition SMLLA continues each Spring and will work hard to make sure it endures well into the future for our neighborhoods. SMLLA is chartered under the Little League Inc. of Williamsport, P.A. and is subject to all rules and regulations contained in their Official Rule Book.

Safety First: SMLLA follows Little League guidelines for the safety and security of the children that enroll in the San Mateo Little League American youth baseball program (i.e. batting helmets, catchers gear etc.). SMLLA encourages parents to go that extra mile to assure the safety of their child. Many parents choose to mitigate the risk of head lice and purchase personal batting helmets for their child. Other considerations might be mouth guards, batting helmets with a face guard, a chest protector for pitchers by IsoBlox or EvoShield or a pitching helmet by Halo or IsoBlox. At SMLLA, we believe that you can never be too safe.

Note: The City of San Mateo does post when they close all fields. We have the permits for Trinta Park and the City knows how much time and effort that we put into the fields. They have graciously let SMLLA determine if a game should or should not be played based on field conditions. They are keenly aware that SMLLA would not do anything to compromise the integrity of our beloved fields.
