League Age & Divisions

How does your player’s age affect the division they’ll be in? It’s a key way to identify the starting point for players in the league.

It’s not always the only factor, though – you can see that there’s some overlap in the groups below. Players who want to play in AAA and above will need to attend a tryout/evaluation. One or more are offered before every season begins.

SMLL has established the following age groups:


A player’s “league age” for baseball is the age they will be by the end of August 31 in the current season’s year.

Division - League Age Range
Tee Ball 6-4 years old
Minor Coach Pitch 6-5 years old
Minor Player Pitch 9-7 years old
Minor AAA 10-8 years old
Major 12-10 years old
50/70 13-11 years old


A player’s “league age” for softball is the age they were at the end of the year preceding the season. In other words, how old were they last Dec 31?

In the first year of SMLL softball, 2023, we used age-based divisions to align with nearby fastpitch youth leagues that use softball’s more conventional 2-year groupings. We expanding each division in 2024 to create larger Minor and Major divisions and facilitate a strong Junior team.


Division - League Age Range Birth Years
6U (Minor Coach Pitch) 6-5 2017-2018
9U (Minor Player Pitch) 9-7 2014-2016
12U (Major) 12-10 1 2011-2013 2
15U (Junior) 15-12 3 2008-2011 2


Division - League Age Range
6U (Coach Pitch) 6-5
8U (Coach & Player Pitch) 8-7

See the Little League age calculator for more information.

Please Note: Only players age 8 and above must attend a player tryout/evaluation.

  1. 12-year-olds may dual-roster in both Major and Junior softball 

  2. aligns with the age range for a Little League softball tournament division  2
