But you're on to something: Going back to '11, here are the 1st Half/2nd Half OPS Allowed numbers for Hammel:
'10 .719/.790
'11 .754/.820
'12 .634/.660
'13 .814/.806
'14 .637/.754
'15 .611/.856
'16 .699/.738
I don't know if that is true for most MLB starters....but Hammel gets creamed in the 2nd 1/2 of seasons. Which makes me wonder if THAT was the real elbow problem he had in the post season.
