Willie Mays is about to get his name on an entire complex of ballfields in San Francisco, and it is not a small makeover. Yesterday, the San Francisco Recreation and Park Commission signed off on renaming the Crocker Amazon Baseball and Softball Complex as the Willie Mays Fields of Champions, tying the new moniker to a major renovation of the park’s western half that city officials say could break ground as soon as 2027 and open in 2028.

The San Francisco Recreation and Park Department pegs the overhaul at roughly $50 million, fueled by the 2020 Health and Recovery Bond and a partnership with the San Francisco Giants, who are set to chip in about $28 million in cash and in-kind support; Mays’ Say Hey Foundation has committed a $5 million lead gift, according to San Francisco Recreation and Parks. The department estimates the renovation could expand access to safe, high-quality play by up to 10,000 additional hours per year, and commissioners have recommended that the Board of Supervisors accept the Giants’ grant as the project’s next formal step.

What the plan would build

Project materials from the Giants and city planners sketch out a multi-diamond complex that would serve everyone from Little Leaguers to high school teams. The concept includes two full-size fields suitable for high school competition, three youth diamonds, covered batting cages, upgraded lighting and new restrooms, while retaining one natural grass field for flexible community use, according to the San Francisco Giants. The Giants’ materials say the design would rely on next-generation synthetic turf that is intended to cut weather-related closures and could add roughly 2,000 hours of play during winter and spring seasons.

Design review and schedule

The project’s Civic Design Review packet backs up those choices with numbers, noting that spring 2023 and 2024 saw dozens of days when fields had to be shut down, and arguing that synthetic surfaces would significantly reduce rainouts while allowing more scheduled games and practices. The CDR presentation also lays out a tentative schedule that carries project development and design work through 2026, with construction activity potentially starting in 2027 and completion targeted for 2028-29, though all of that remains subject to regulatory review and community input; see the Civic Design Review presentation for details.

Neighbors raise turf and tree concerns

The grand plan is not exactly sailing through without pushback. Neighborhood activists and environmental groups have come out against replacing mature grass with synthetic turf and removing dozens of trees, arguing the redesign would shrink informal open space and hurt park users who do not take part in organized athletics. Supervisor Chyanne Chen has called for more public meetings, saying the proposal “would fundamentally change the character of the park and limit access for many current users,” the San Francisco Chronicle reported. Local TV coverage has also highlighted Recreation and Park’s assurances about new infill testing and a two-for-one tree replacement policy, according to ABC7.

Next steps

For now, Rec and Park commissioners have urged the Board of Supervisors to accept the Giants’ grant. If the board signs off, the Willie Mays Fields of Champions name would be formally attached to the complex as part of the renovation, the department said. Community members still have a chance to weigh in: residents can review the concept design and talk with project managers during two workshop sessions on Sunday, April 26. Spanish and Chinese interpreters will be available, and RSVPs can be made through the department’s project page, according to San Francisco Recreation and Parks.
