The Minor “AA” division is for players age 7 to 11 years of age that are drafted following tryouts. 11 year olds must waive down to play at this level. This division is intended to be an introductory competitive division. Managers and Coaches should keep this in mind as they develop the skills of all players on their team. This is a partial kid, partial machine pitch division using a hard ball. Umpires call balls & strikes. Games are 6 innings but may be called due to time. Batting orders are continuous. Players and parents should expect 3 games and/or practices a week.
