For Single A - Majors, SMLLA runs a draft. Managers of each league draft players one round at a time. The managers do their best to evaluate each participant at tryouts.  It is up to the manager to select a participant for any given division. The league can't guarantee a participant will be chosen to any specific division. However, every player will be selected for a team. 
Wiffle & T-Ball teams are built by the league taking into consideration buddy requests & school info.
