Sponsors play a vital role in supporting the Castro Valley Girls Softball League, contributing to its growth and success. Through their generous contributions, sponsors provide crucial financial assistance that helps cover equipment costs, field maintenance, and league operations. Their support enables the league to offer affordable registration fees, ensuring that all girls, regardless of financial background, can participate in the sport they love. Additionally, sponsors often foster a sense of community by actively engaging with players, families, and volunteers, strengthening the bonds within the league and promoting a positive environment for young athletes to thrive.

Sponsorships are $500 for the season.  Logo will appear on a team's jerseys.  At the end of the season plaques are presented to the sponsors for recognition and gratitude.
