MGS Tremors Black is the A/B team program from MGS Tremors. The MGS Tremors Black teams will form following tryouts in November and December and start practicing in January. MGS Tremors Black players will still participate in the MGS recreation season, with additional practice sessions, and early season tournaments on non-MGS weekends, to help fine tune the team for the summer travel ball season.

MGS Tremors Black is for players, and their families, who love softball and are committed to the extra effort to compete at the highest levels in the state. We encourage all of our returning players who want to play through the year, to come and tryout for the Tremors Black team. For these players, softball is their primary sporting activity from January to July.

Professional coaching, indoor facilities for the winter months, and specialized conditioning programs are just some of the features of this program.

Marin Tremors Black will form teams in 10U, 12U, and 14U, and compete in Open, A, and B-level tournaments, including out of area and interstate events.
