Divisions play in the Spring and Fall seasons. Spring teams are drafted after a skill assessment. Fall teams: each coach may freeze up to six players in total, including 2 pitchers and 1 catcher. OMGS then builds the rest of each team, keeping teams as balanced as we can by looking at experience, positions, and more. Summer All-Stars are for 8U through 18U and have their own tryout and draft.
Playing up
"Playing up" is on a case-by-case basis, reviewed by the board, however these conditions must be met in order to be allowed to play up. The player must be in their last year of an age group (Ex. second year of 10U asking to play in 12U) and must have played All-Stars in that age group, a parent must volunteer to be a coach, and the player must be listed as a coach pick. Also, being allowed to play up means that that player must try out for the age group they are placed in for all-stars, they may not play back down. The player may be granted to play up to one age group but will then have to request to play up again the next season and continue to meet the conditions to play up.
