We try to grant friend requests but do not guarantee it and do not consider friend requests after registration deadline.  We attempt to make balanced teams in terms of numbers and consider skill levels of the players.

Coaches pick practice days/times so we do not know the practice day until we discuss with the coach.

We follow the rules of Marin Girls Softball and teams are formed based on a 2-year age groupingnot by school grade level

Interview with Cornell softball player and Tam High graduate Kim Scarsella

Kim Scarsella, Cornell University

"Softball is the main thing I remember from growing up, so I would pretty much equate my MVGS experience with my childhood experience. I was a shy kid, so having teammates and a sport where I excelled did a lot for my self-confidence and social skills. It's been 20 years since I first joined MVGS (whoa) and some of my best friends today are former teammates. Being part of a group that works toward a shared goal is an amazing bonding experience, and my friends and I still reminisce about our early softball days!


I would encourage every young kid to join MVGS. Being part of a team has so much value, but beyond that, softball is special. It's a technical game with so many facets. There's room for a huge range of skills from mental strategy to physical coordination. It really is a game of specialties, which means there are so many opportunities to fit in."
