Every season, between 18 and 22 games are played by the San Lorenzo Little League, a non-profit organization that plays its games at a sprawling 9.2-acre, five-field facility at 1062 Grant Avenue. More than 400 girls and boys between the ages of 4 and 18 participate in the games, from the T-ball division to the big league. The long-time institution stays afloat primarily through sponsorships, though it also charges $100 to participate, with discounts offered for early sign-ups and for siblings.
