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.

If you anticipate coaching for the 2025 season (September 2024 through August 2025), this registration must be completed before all other certifications. Please get in touch with your district for information regarding all certifications required for coaching!

*Please note that the instructions are located at the bottom of the "Coaches Corner" page*

2025 umpire registration is now closed.  Reach out to Madie Augusto, madieaugusto.mgs@gmail.com, with any additional questions!

Marin Girls Softball League, with almost 1,000 registered players, is one of the largest youth softball leagues in California.

We're a volunteer-driven league for youth fast-pitch softball in Central and Southern Marin County.  We operate as a USA Softball district program - providing an educational-athletic program for any age-eligible child.  Any child can register and all registered kids play. 

Marin Girls Softball aspires to be an outstanding educational-athletic organization, providing and expanding opportunities for softball players across Marin, from beginner (recreational) through to competitive travel-ball programs.

Marin Girls Softball aim is to offer a high-quality experience for every player.  A high-quality experience is one in which every player: 

1. Is coached using the principles of positive coaching, developing confidence and self-esteem in every player
2. Has fun at practices and games
3. Feels like an essential part of the team
4. Learns to promote sportsmanship, integrity, and teamwork 
5. Learns “life lessons” that have value beyond the playing field
6. Learns the skills, tactics, and strategies of the game, and improves as a player
7. Has the opportunity to develop their game to their desired level: recreational, competitive travel-ball, and preparation for high school softball.

Marin Girls Softball recognizes that coaches, officials, and parents are the people who most directly make this all possible. It is our goal to provide every coach, official, and parent with a clear understanding of this mission, and the tools necessary to succeed.  

We are committed to creating a positive culture, in which coaches, officials, parents, administrators, and players, work together to achieve our mission.
