Standing United with #Black Lives Matter

The game of softball doesn’t discriminate.  Our players, coaches, officials, and volunteers come from a diverse range of ethnicities and socioeconomic backgrounds.  

On the field, our players learn to respect one another based on their efforts as a player and a teammate.  It has been said multiple times that newborns don’t discriminate. It’s a learned behavior.   We as coaches, officials, and administrators of Marin Girls Softball know that we can have a positive influence on the actions, language, and behaviors of our players and our community, and we are committed to creating an environment where the values including inclusiveness, effort, and teamwork are demonstrated and encouraged every day, and discrimination in any form is not accepted.

MGS Softball Players,

Unfortunately, there will be no summer recreation softball league for Marin Girls Softball this year.

We’ve come to this difficult decision because - per current MHHS guidelines - there is no clear timeframe by which we would be allowed to commence open practices or to start playing games between local teams.

Thank you to all the parents and volunteers who jumped in to help keep the season a possibility. In particular, the MGS board would like to thank the efforts of the Summer Recreation League Sub-committee, led by Pete Searson from MVGS, for all the effort they put into creating a plan for the season, building registrations, and organizing umpires and fields, knowing full well it might not happen, but putting in the effort because they know how important it is to our players.  

The good news is that planning for next season is starting now.  The entire MGS board, and the districts represented, are all committed to making the 2021 season the best season ever.

Marin Girls Softball Board


Marin Girls Softball has been working closely with Marin Health and Human Services (MHHS), and the Marin Recovers Youth Sports Advisory Committee, to develop a set of guidelines by which we could recommence practices, and ultimately games.   These guidelines will be reviewed this month by MHHS, and depending on how the numbers (cases) look, we expect to hear back from MHHS by the end of June at the latest.  Any programs that commence this season will do so, strictly following the guidelines laid down by MHHS and the CDC.

Will there be a Marin Girls Softball Summer Recreation League This Summer?
We hope so. In fact, we have a sub-committee of MGS volunteers who have been working diligently to develop a plan for a seven-week season that could start as early as the last week of June, or as late as July 11th and finish on August 20th, depending on if and when we get the go-ahead from MHHS.   

The season will require some planning and logistics to manage registrations, team formation, field, and game scheduling, so the latest date we can make a decision to hold a season will be June 15th.  

If we hear from MHHS by June 15th that we could start, we will release a registration form to all MGS players.  

The registration fee will be $195 and no registration fees will be processed until the season commences.  That way, if anything changes, no players of families will be out of pocket or refunds will be necessary.


Our first priority is the safety of our players, coaches, umpires, volunteers, and their families, and so any continuation of our softball season will be coordinated with direction from local, state, and national authorities, and USA Softball, our governing body.  

While news over recent days suggests that things will get worse before they get better, we believe that when they do get better, getting our players back to participating in sport and reconnecting with their friends will be a very important step in returning to some level of normality. 

So, following on from the announcement by Marin School Districts to remain closed through May 1st (and assuming this happens), the MGS Board has revised the plan for our recreation softball season.

Here are the key points of the revised 2020 MGS Recreation season plan:

1. The MGS Recreation season, including games and practices, will restart Monday, May 4th, and be extended through Saturday, June 6th.

2. All games from May 4th through May 17th remains as originally scheduled.

3. A revised schedule from May 18th to June 6th will be published by May 7th. We’re looking to provide all teams with additional games as resources (fields, umpires) allow.

4. There will be no playoffs at any age group.

5. Games will scheduled on Saturday May 23rd (Memorial Day Weekend). Please make sure you keep your coaches up to date on your availability.

6. All teams (age groups) will be allowed to call up or across (same age group) players from any district to support a roster of up to 10 players . All other age-level rules remain the same.

7. The MGS Board is currently exploring offering a MGS Summer Recreation softball season, especially in the event that the Spring season is cancelled. More information to follow shortly.

Of course, there is still some uncertainly as to whether school districts will re-open after May 1st, or whether there will be further restrictions when they do. We will continue to monitor the situation and provide updates as the situation develops.

Be safe,

Marin Girls Softball


As many of you will have already heard, a number of Bay Area counties, including Marin, have implemented a shelter-in-place order restricting activities to only those considered essential services. 

This order came into effect at 12:01am this morning, and will be in place until at least April 7th. 

The MGS Board had already announced that should the need to pause our season extend beyond March 30th, that we would recommence after the scheduled spring break on April 13th.

We will continue to monitor the situation, and provide updates to the season start as the date nears. 

For more information on the shelter-in-place order for Marin County, please visit


In support of the decision by some of the Marin County School Districts to close over the next two weeks, and at the request of the USA Softball NorCal Commissioner, the Marin Girls Softball board has voted to postpone the 2020 softball season until at least Monday, March 30th, 2020.

Effective immediately, no opening ceremonies, games, clinics, or practices will take place until Monday, March 30th at the earliest. 

Assuming schools reconvene on Monday, March 30th, games and practices will recommence on that date, based on the existing schedule.

If schools do not reconvene on March 30th, we will move the resumption of games and practice to the week of April 13th.

Games that were supposed to occur during the postponement will not be rescheduled.

More information on plans for when our season recommences will be posted here as they develop.


Summer League Possibility


A decision on the possibility of a summer rec league will be made by or before June 15. You can continue to monitor this site for updates as they become available. 

Pitching clinics

MGS pitching clinics are here.  This season they're open to all 8U through 15U players from beginner to advanced.  Signups open at 9:00am Tuesday, January 14th.

Beginner Pitching Clinics - 8U, 10U, 12U, and 15U Welcome!

MGS recently announced our intent to discontinue adult coach-pitch for 10U in 2021 (next season).   As a result, we're encouraging  8U players that are interested to start attending pitching clinics as soon as possible.  Likewise, all players that have had an interest in pitching can benefit from understanding the skills.  Sign up for these beginner sessions, hosted by MGS at Red Hill starting January 26th.

Sign Up!

Intermediate Advanced Pitching Clinic (10U-15U only)

Conducted at Bacich Community Center, these sessions are indoors and will happen rain, hail, or shine.  These sessions are limited to 5 pitchers per session.  There is no charge for these sessions, however, players are limited to 2 session sign-ups at any one time.  This is an investment in our players by MGS, therefor no-shows will not be tolerated and will result in suspension from attending these clinics for the remainder of the season.

Sign Up!
