Divisions of play / age groups


Players are evaluated before the season and placed in a division that best matches their age, skill, and experience.  The number of divisions and teams each season is based on the number of girls of an age group registered. In some years, age groups may be combined in order to create enough teams, but never to the detriment of player safety.

For Spring 2022, we expect to conduct player evaluations and form teams by mid-January, commence practices by the end of January, and schedule games from mid-March through early May (late April for 6U).  All teams, except the 6U, will participate in the Peninsula League, playing both against each other and teams from neighboring cities. Our home games will be hosted at the Cabrillo School fields and an additional field in Pacifica if needed.
