Divisions within each age group will be formed based on number of teams, the competitive levels of the players, and other factors.

6-8 is an open division. 8 D1 is an open division. 9-14s we offer 3 divisions.

An example for division breakout is below:. 

D1 - Highest Level. Teams that were 11 Majors or 11 AAA (upper) this past spring would likely fall into this division. Possibly some 11 AAA (lower) teams as well.

D2 - Medium Level. Teams that were 11 AA or 10 Majors this past spring would likely fall into this division. Possibly some 11 AAA (lower) / 10 AAA (upper) teams as well.

D3 - Lowest Level. Teams that were 10 AAA (lower) or 10 AA this past Spring would likely fall into this division.
