Norcal Fusion

Tremors Summer 2025 Travel Ball Tryouts!

Marin Tremors will be holding tryouts for the Summer Travel Ball Season on Sunday, April 27th.  UPDATE: 14U and 16/18U will now be Sunday May 4, at Del Mar 10 am-12pm  

This summer we'll be fielding 8U, 10U, 12U, 14U and potentially a 16/18U team in B/C-level tournaments around the North Bay area. Each team will compete in approximately five tournaments. Some teams will compete in Western Nationals come the end of July!

To register for the Marin Tremors Travel Ball tryouts, please visit https://maringirlssoftball.sportngin.com/register/form/878292448

(Registration will close at 7:15 PM April 26th for tryouts on the 27th)

Alternatively, if your athlete is interested in continuing to play over the summer in a relaxed local setting, we will be opening registration in early May for our Summer Tremors Club Season. Open to 8U, 10U, and 12U players, this program typically offers one evening practice per week and Saturday doubleheaders in Marin. 

It’s a great way for players to keep developing their skills, stay active, and have fun. The summer schedule also works well for families planning to travel, as the Club program is designed to be flexible.
