What are the Little League Age brackets?
Little League has chosen for baseball to align kids ages around a September to August Calendar span to ensure kids particiapting at the Little League World Series are the appropriate age for their respective division. This differs from other sports in the Calgay area - however as a Little League Chartered Association we are required to follow the age brackets as they are established in the Little League Rule book
Those age brackets are as follows:
What are the Divisions?
T-Ball LL Ages 4-6*
Young players are introduced to the game of baseball. They learn, develop and practice fundamental baseball skills at an early age to receive maximum enjoyment from the experience. Emphasis is placed on participation and enjoying their first baseball experience.
Rookie Ball LL ages 7-8*
Players continue to develop their skills and learn the rules of baseball. Emphasis is placed upon hitting, base running, fielding/ throwing and teamwork. Both Offensive and Defensive fundamental are stressed.
American League and Minors LL ages 9-10*
Players are evaluated for the first time in Majors. Player pitching is introduced, and all players are encouraged to try pitching. Umpires in this division allow a fairly liberal strike zone. The object of the game is to get the ball hit into play as often as possible. Players are encouraged to play all positions throughout the season. This is the first age group where All-Star teams can continue with Tournament play after the season ends.
National League and Majors LL ages 11-12*
Players are drafted based on their ability and Players development to either a Majors or or a National League team. The number of teams vary year to year depending on enrollment.
