Once you complete the online registration for Winthrop Youth Lacrosse, YOU MUST register your player with US LACROSSE via www.mbyll.org
ALL PLAYERS must be registered with US Lacrosse to play in Mass Bay Youth Lacrosse league. Use the link above to set up an account for your player and register them. You will receive an email confirmation at the conclusion of your registration and I ask that you please email that to email@example.com.
