This is something I have wondered about. I generally lump each category of relief pitcher as the same, i.e., all closers are A, all set-up are A, all Long are A. This gives Sparky the chance to use them interchangeably. Does anyone know how Sparky makes the choice, if all pitchers of a given type have the same fatigue? Is it therefore a random selection or is their some hierarchy in the SIM that makes the selection?
