Doctor G said:i would guess the right knee that started his slide last year is still the culprit.
Ehh, possibly. But he was pretty terrible every month last year, and didn't go to the DL until July with this knee "inflammation". Hard to read between the lines since inflammation is so nonspecific, but I doubt he had anything significant wrong with his knee since he pitched again 3 weeks later. The more likely scenario to me is that the knee thing was a very minor issue he would have pitched through if it wasn't for the fact that he was getting shelled at the time (14.40 ERA in July).
This season, instead of bouncing back, his velocity is continuing to decline and he has no command whatsoever. If it's still his knee 10 months removed from his "inflammation" DL stint, he has a significant knee injury the Red Sox probably should have known about before they signed him. I'm betting shoulder or elbow injury, regardless of how the Red Sox spin it if he goes on the DL after tonights pathetic performance.
