MGS Tremors has played a very special role in the path these players have taken to college. For all these players, their first experience of travel ball softball was with MGS Tremors. We are incredibly proud of the journey they have all taken.

Marin Tremors Fall Ball Tryouts will be held Sunday, August 18th (16U/18U) and August 25th (8U-14U) at Memorial Park, San Anselmo.
The season runs from Sept to October. Teams will compete in three tournaments with 1 to 2 practices per week.
The Fall Ball season is a more relaxed season than the summer travel ball season. It's also a great opportunity for Tremors Club players who would like to try travel ball.

Two distinct softball programs tailored to different player commitments and skill levels: the Club Ball program and the Travel Ball program.
Club Ball Program:
Purpose: This program is ideal for players who are developing their skills and may not be ready for travel ball commitments or those whose families are unavailable during the summer.
Teams Formation: Teams are geographically formed.
Age Groups: Available for 8U, 10U, and 12U players.
Schedule: Teams practice once a week and play back-to-back games on Saturday mornings.
Game Play: The game rules align with those used in travel ball, facilitating continued player development.
Registration: Open enrollment without tryouts, but players must sign up by May 19th.
Travel Ball Program:
Purpose: Geared towards players deeply passionate about softball, this program involves more competitive and frequent gameplay.
Teams Formation: Players must demonstrate their skills at tryouts to be selected.
Age Groups: Open to 8U, 10U, 12U, and 14U players.
Schedule: Teams practice 2 to 3 times per week and participate in 5 to 6 local tournaments in the North Bay area.
Game Play: Each tournament can include up to six games, providing extensive playtime and competitive experience.
Tryouts: Players must attend tryouts on April 28th to qualify for team selection.
Key Differences
The Club Ball program does not require tryouts and has a more relaxed schedule with once-a-week practices and games only on Saturdays, making it suitable for players looking for less commitment.
The Travel Ball program demands a higher commitment with more frequent practices and multi-game tournaments, designed for players who are more serious about advancing their competitive softball skills.
MGS Tremors Black is the most competitive team program for MGS Tremors. Teams compete in Open, A and B tournaments around the Bay Area and state.
