Because of this, Crow has HEAVY platoon splits. LHP has traditionally beaten him up quite a bit (needs that changeup to really mess with their bat speed).
It doesn't make sense. I saw him pitch a lot in college, and he flashed a 40/45 changeup consistently there. That's a good enough pitch to project to MLB average, but it just never came.
