Marin Girls Softball League, with almost 1,000 registered players, is one of the largest youth softball leagues in California.
We're a volunteer-driven league for youth fast-pitch softball in Central and Southern Marin County. We operate as a USA Softball district program - providing an educational-athletic program for any age-eligible child. Any child can register and all registered kids play.
Marin Girls Softball provides programs for 5 to 15-year-olds; from beginner to competitive travel ball. Our goal is to help our players develop both life skills and a love of the game, through a positive coaching experience.
