For whatever reason, he’s mostly been used in single-inning appearances, though he’s had three multi-inning appearances between SF and Milwaukee. I’d imagine a lot goes into that decision, between scouting, analytics, and what the coaches are seeing in throwing sessions. It’s not like managers are going out there, cutting the head off a chicken in some old-timey voodoo ritual, and divining who to trot out there. The manager gets the heat, but the entire organization feeds into these decisions, I think.
