Anecdotally from his recent starts, I’ve noticed his curveball is completely trash, no command of it at all, so that’s one key pitch that missing from his arsenal and when you’re his type of pitcher, you k8nda need them all. 90 mph fastball, 87mph cutter and a change isn’t enough unless they’re all pinpoint.
I don’t know where to look to get his spin rates on a game by game basis either.
