No.  ATB players are not permitted to play for a second travel baseball team at any point during the ATB season, which runs from the fall through the spring/summer.  There are many reasons for this policy. First, we want to protect players from overuse of their arms, and playing on multiple travel baseball teams (in addition to ALL or ABR in the spring) makes that difficult.  Moreover, travel baseball programs often overlap at critical points, forcing players to choose one travel team over another. This is not a positive situation for either team. Finally, because ATB seeks to build team camaraderie over the course of a year-long season, it is not possible to play ATB only in the fall season.  Players who accept roster spots with ATB are making a commitment to their teammates and coaches to play with ATB through the fall and spring/summer seasons.
