Castro Valley Independent Sports League has become one of the largest sports leagues in the area! Last year we fielded 60 teams, providing 750 members from 5 to 18 years of age with an opportunity to learn and play baseball in a fun and safe environment. Family, Fun and Baseball - that's our batting order!

We appreciate your interest in sponsoring a team this year. Our goal is to raise funds to help support the program and provide you an opportunity to be recognized for your generosity. The money raised through our sponsorship program help supports many of the functions and activities of the league such as scholarships, field maintenance, tournament participation, training clinics and equipment. In return, we increase the visibility of your organization through team banners highlighting you as the sponsor, team hats with your name embroidered on the back, links to your organization on the CVIBL website, and signage that is displayed at the snackbar. In addition, you will receive a team plaque, and many thanks!
