2019 Tremors Club Program Registration is Now Open!

Marin Tremors Club Program registration is now open until May 13th at 9:00pm. 

Marin Tremors Club is the development program for players who love softball, but are not quite ready for travel ball, or whose commitments through the summer don’t allow them to participate in a full travel ball program. Marin Tremors Club play Saturday games in June and July around Marin, against other Marin Tremors and local softball program teams.
