Littleton Thunder offers spring lacrosse teams for youth players K – 8th grade.  Littleton Thunder and all AYL teams are grouped based upon grade level, K – 8th.  High school students are not permitted to play in the AYL.

Teams are formed based on age, grade, and playing experience.  Returning players and teams are formed based on coaches and previous experience. Coaches provide input for teams based on previous rosters and team formation. New players will create new teams or be added to an existing team roster based on team numbers.

Registration begins in November and closes when the team’s rosters are complete.

AYL Competition Levels:

The AYL Lacrosse Board of Directors will make the best effort towards dividing each age group into multiple divisions with the goal of like talent and experience levels teams playing against each other. The final placement of all teams in each age division will be at the discretion of the AYL Lacrosse Board of Directors.

  • Red:  Select  / Elite
  • Silver: Advanced
  • White: Intermediate
  • Blue: Beginner / Recreational

The AYL is a community focused league.  In the past, all sports but boys lacrosse have adhered to a strict in-territory/out-of-territory roster mix.  For 2018, this policy will be extended to lacrosse.  The roster mix for the upcoming season is 70% in territory for Blue, White and Silver level teams and 50% in territory for Red level teams.  With the adoption of this policy, ALL rosters will go through an audit and sign off process to be conducted by the AYL Lacrosse Board.  

To be considered in-territory, a player must:

  1. Live within the club's boundaries
  2. Attend a school within the club's boundaries   

If you should have questions regarding your player's status, please email: boyslacrosse@littletonyouthsports.org
