The Big West Fastpitch League of Minnesota and Tri-County Fastpitch League separate age divisions based on calendar year and not education grade level. For 2017:

Age Group Birthdays in the calendar year:
8U (8 and under) 2010, 2011
10U 2008, 2009
12U 2006, 2007


Please visit our Age Division Structure webpage for information on how we plan our teams for the season.

Please visit our 2019 8U Fastpitch Rules webpage for the rules that govern 8U gameplay and its differences from 10U or 12U fastpitch softball.

We no longer host a softball program for our younger daughters with a birthday in 2011 or younger. While softball skill development remains our primary goal for all age groups, we will not jeopardize a child's safety and put them in competition with other fastpitch softball teams which may comprise of girls 2-4 years older than your daughter.


  • as of "MAY2017"- when regular season games start
    • if your daughter has a "NOV2010" birthday, she will be 6 throughout the summer season
    • an opponent's team could have players with birthdays in JAN2008-JUN2008 making them 9 before the start of (or turning 9 during) the season. 
    • any child with a birthday in "2011" or "2012" (5-6 yr olds) would be at a significant size disadvantage compared to other teams which may be comprised of 8-9 yr olds
