The American League is for girls ages 8-14. This program is for recreational or competitive recreational players looking to develop good fundamentals.

Registration (2 steps)

1) Register the team Nov. 1st – Dec. 2nd.  No fee required.  As you register the team, you will input an expected roster.  Then you will "Invite" the parent who will get an email with a link to register.  Rosters can be edited and players added or removed as needed.

 2) Players register.  After registering the team, those expected roster players receive an email with a link to register.  Be sure to check SPAM or junk mail for the email.  Player fee is $145 and players should register by Jan. 31 (late fee of $25 after Jan. 31)

  • If a player DOES NOT have a team, they may register Dec. 1-Jan. 31 and CBSA will try to find them a team.  Player fee is $145/player. We also encourage you to check the ads, or create your own, our American Softball discussion boards.
