Girls Youth League


MSLC is a member of the Washington Girls Youth Lacrosse (WAGLAX) . The MSLC Girls Youth Program is comprised of the following four divisions:


  • U15: This Division is designed for teams comprised of programs of 7th and 8th graders. 6th graders are allowed to play with this level if there is no program for them to appropriately play at the U13 level.
  • U13: This Division is designed for teams comprised of 5th and 6th graders.
  • U11: This Division is designed for 3rd and 4th graders who play a modified game of 7 v 7, and a simplification of the rules.
  • U9: This Division is the entry level of the sport and is designed for 2nd grade players. They practice in a six-week clinic format with a set of games played at the League's End of the Season Jamboree.

Spring season generally starts the last week of February and runs through early June. Occasionally, a tournament team will form and play at competitive tournaments in the Northwest.  Fall Ball runs September through November.
