Update on Participation

By Athletic Director, 09/03/21, 7:33PM CDT



St. Isidore’s CYO basketball program is a member of the Tri-Valley CYO league. The CYO parish members of this league are in Livermore, Pleasanton, Dublin, San Ramon and Danville. During the 2021/22 basketball season, the Tri-Valley League has decided to only sponsor basketball competition for boys and girls in grades 7 and 8 only. 

For the 2021/22 season, St. Isidore CYO basketball has committed to offer competition in all grade levels, 3 – 8, for boys and girls. This will be accomplished in the following way.

Grades 3 and 4 are will play an ”in-house” format. Games and practices will be held at our gyms at St. Isidore parish. If viable, fourth grade girls and boys “A” teams will be offered for competition.

Grades 5 and 6 will participate in competition in the East Diablo CYO and West Diablo CYO leagues. Both leagues are located in East Contra Costa County with teams located from Orinda to Antioch.

Grades 7 and 8 will play in the Tri-Valley League sponsored competition in addition to games teams from the East and West Diablo Leagues.

Start date for games will not be before November 7 with regular season competition ending by the first week of February.

We are confident that these options for the 2020/21 will achieve the goal to offer excellent CYO basketball competition for all grades and levels of play. If you have questions, please contact me at with your questions and comments.

Thank you for your interest and support.
