Stacks is where MLBU BASE results live
The Baseball and Softball Evaluation (BASE) is the MLB-backed evaluation that measures every athlete's game using trusted, standardized technology. When a player completes one, their results flow into Stacks within hours. Coaches can see where every athlete is in their development, track progress across sessions, and guide improvement.
