Look at Papelbon's last two years
09: 68 IP, 54 hits, 5 HR, 24 BB, 76 K
10: 65 IP, 55 hits, 7 HR, 26 BB, 73 K
Those numbers are almost literally the same, the difference? In 09 he had a 1.85 ERA and this year he had a 4.02 ERA. His peripherals are still good and he's still better than anyone we are going to be able to find.
Okajima's peripherals have been plummeting for a while now and it's really showing.
