MGS Tremors is the competitive travel ball and summer club program for Marin Girls Softball.  Marin Tremors is open to all registered Marin Girls Softball players and field teams from 8U to 14U. 

MGS Tremors hosts teams with players that range from the elite, to the developing player.   We are incredibly proud of this focus, ensuring that every player that wants to continue developing their competitive softball, has the opportunity to do so.

Our programs start in January (Tremors Black), May (Tremors Gold and Club), and September (Tremors Fall Ball).

The 16U/18U Team

There are so many talented 16U and 18U players in Marin that play in high school but choose not to play in the rigorous A-ball fall travel ball season.  To provide these players with a fun way to keep their skills up over the fall  Marin Tremors will be fielding a 16U/18U team.  We'll keep the schedule LOCAL and light! (no trips up and down the I-5 or to SoCal!).   Other North Bay programs are doing similar, so if the idea of playing locally sounds more enticing than playing in Manteca and Stockton, this could be your fall gig!

Click here to register interest for the 16U/18U team for this fall.

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.
