Our Fields

Home Field

Trinta Park (1950 Leslie Street, San Mateo, CA) is home to SMLLA and is primarily used to host Games. There are two full fields (North field and South field), a batting cage, a Snack Shack, and a playground and basketball hoop area.   The younger age divisions typically play on South (which is has smaller dimensions) and the older kids typically play on North (which is larger).

All of our fields, including Trinta, are managed and maintained by the City of San Mateo, Parks and Recreation Department.  SMLLA is an authorized,/permitted user during our Seasons (Spring and Fall).  SMLLA maintains the infield at our home field, Trinta Park.

Up-to-date Field Status

Games are played in the rain unless field or weather conditions become a safety hazard. Please assume games at TRINTA are ON unless you see a text alert or see an update from your manager.  Managers will be notified when games are postponed because of rain.

For practice fields other than Trinta, please review the San Mateo Parks and Recreation Field Updates Twitter Page or call the Field Conditions Hotline at (650) 522-7439. 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 our fields. They have graciously let SMLLA determine if a game should or should not be played based on field conditions.
