2018 Summer and Fall Tremors Program

2018 Season Schedule

We haven’t even started the Rec League Softball season yet, so why are we talking about Summer and Fall Travel Ball???

Well, like you, many of us are currently planning our summer vacations, so we felt it might be good timing to let you know when the Tremors Summer Ball and Fall Ball programs will be running.  We’ve been contacted by numerous parents, who would love to know, so they can schedule vacations that don’t conflict with the season.

In 2018, we will be fielding at least one travel ball team for 8U, 10U, and 12U.  We will be fielding Club Ball teams for 8U and 10U.

In addition, there are some other important dates to start planning around in 2018.  Read more by clicking here.



We will be holding 4 Marin Tremors Clinics at Del Mar from 9am-12pm on following dates: March 18th, March 25, April 15 & April 22.

Please sign up via the below spreadsheet link for up to 2 clinics per player in advance and return here to pay for the clinics below.

Welcome to the home of the Marin Tremors.  Marin Tremors is organized by Marin Girls Softball and is open to all registered Marin Girls Softball players. 

What is Marin Tremors?

Marin Tremors is a competitive softball program conducted over the Summer and Fall.   We believe that every player that wants to continue their softball development into the Summer and Fall should have an opportunity to do so.   This includes the experienced competitive travel ball players, and the players who love the game, and are looking to further their skills.    In addition to taking 11 players from each age group for the competitive Travel Ball program, in 2017 we added a Club Level program.  Both of these programs are described below and are offered for 8U, 10U, and 12U players (assuming resource availability).  The summer season will run from May 6 to July 15.  Fall season runs from September through October.

The two programs include the traditional competitive Travel Ball program and a Club Level Program.  Both programs play and compete under USA Softball rules for their specific age groups, giving all players a chance to experience the excitement that competitive softball has to offer.

Marin Tremors Travel Ball teams compete in B/C Level tournaments around Northern California.   Travel Ball players are selected during the tryouts/assessment day,  and selected players must be able to commit to practice 2 times per week during tournament weeks, and 3 times during non-tournament weeks.   In addition to practices, players need to be available to commit to at least 4 of the 5  scheduled tournament weekends over the Summer season.

Marin Tremors Club Ball teams play officiated games against each other and other districts with similar level teams.  Games are played on Saturdays at locations around Marin.  Club Level Ball teams practice 2 times a week.  Club Level is an ideal way for players that are looking to get an introduction to Travel Ball rules, are developing their game, or due to other plans, are unable to commit the entire season.
