Each summer and winter, SBG Sox hosts tryouts in Jackson, Hattiesburg, Gulf Coast, Birmingham, and Auburn AL. Tryouts are comprehensive and can take over an hour as players are evaluated by staff to determine the skill level & positions of the players. Invitations are extended as early as the night of the tryouts, but can take up to two weeks as over 1,500 players will attend summer tryouts. When an invitation is extended, the roster spot is held for 24 hours for the player, then the next player on a roster is extended. Rosters are completed by early August and in November.  Players and families sign their contracts in August, and the season begins on September 1 of each year, with winter players added for Spring.
