Fall Ball is a time for players to further develop the skills that can take them to the next level in the Spring.
In Fall Ball, Tee Ballers looking to move off the tee can get some plate appearances, pitched to by their coaches. Minors A players looking to move to player-pitch can do so in Minors AA. And so on and so on! Players who just want to play in the off-season, but don't necessarily want to move up in Spring are welcome as well!
The Fall Ball season is real baseball, but with the focus even more on fun and development than the "real" Spring season.
