UPDATE

Due to weather and field closures, MGS Tremors is holding its tryouts indoors at LaunchPad Marin.

10U tryouts will be held 4 pm - 6 pm Friday, January 6th.

12U and 14U (two teams) will be held 6 pm - 8 pm, Saturday, January 7th.

ALL PLAYERS must register below if you're planning to attend.

The Tremors Black season runs from January to July in a spring session and a summer session.  It's the most competitive program of Marin Girls Softball.   Players will practice and compete in 1 or 2 tournaments prior to the MGS Rec season, practice once a week during the Rec season, and head into the competitive summer season with a goal of qualifying and competing in the Western Nationals.  

Tournaments are typically held around the Bay Area and the Western Nationals will be held in California (San Diego, Hayward, or Clovis).

Teams will practice two to three times per week prior to the rec season commencing,  one day a week during the rec season (Sunday), and 2 to 3 times a week during the summer.

Approximately 12 players (and possible practice players) will be selected for each team.  

Typically we look for a maximum of three pitchers and three catchers per team.  This ensures those players will get plenty of pitching and catching time to help them develop.

Coaches will be selecting players for their teams from the tryouts.  

Player Notification

All players selected for the Tremors Black teams will be notified within 48hrs of the tryouts.

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