I haven't quite figured it out but some pitchers, even the ones who should be able to go 85-90 pitches, do ridiculously better at 50-55 PC. It seems, and I don't have a lot of data to work with, that the guys with no "out" pitch but several average to above average pitches do better with the shorter PC. Looking at his ratings, I'd expect better than his 1.55/5.50 numbers in any role.
