CBSA Announcements

Softball Age Levels

CBSA will follow the new USA 2024 Age Level Cutoffs.  Previously, age cutoffs followed the calendar year.  The cutoff date is closer to most school cutoff dates and allows players to play more often with those in the same grade. So players born in September-December are now able to stay back to play with their classmates. It also gives an extra 4 months of eligibility (September through December) for 18u players.
