Age in Little League (known as "LEAGUE AGE") is based on the age that a player will be on August 31st of the baseball season that they are (or will be) playing in. For example, a player who will turn 9-years-old on July 11th of a current year's spring season is considered to be "League Age 9-years-old"—even though he is actually 8-years-old for the duration of the spring baseball season (which ends mid/late June). To determine the League Age of your player, you can use LittleLeague.org's League Age Calculator or the chart below: All 12-year-olds are placed on Majors teams barring extenuating circumstances that warrant a waiver (e.g., brand new to baseball or safety concerns). All 11-year-old 6th graders are placed on a Majors team, unless safety concerns and/or parental preference warrants placement on a AAA Minors team. All 10-year-old 5th graders who are not drafted in Majors will be placed on a AAA Minors team, again, subject to safety concerns or parental preference. All Rookie & Tee-Ball teams (ages 5 – 8) are assembled by the League's Player Agents in an attempt to balance team sizes and skill levels. While you are welcome to request that we pair your player with another, there is no guarantee that it can be honored.
