Marin Tremors Summer and Fall Ball 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.

We have opened Tremors Spring Clinic sign-ups.  Click here for Tremor's homepage for details & sign-up.

In addition, there are some other important dates to start planning around in 2018.  Click here to get the season schedule.
