A change of approach 6 years into your career is probably not the easiest thing to do, especially when it seems to be abandoning his bread and butter "out pitch" -- his sinker. His last start he pitched very well while down in the zone. He never got hurt down in the zone. When he was up in the zone he overpowered a few hitters for k's, but then he got hurt with the HR ball. The only times that he got hurt was when he was up in the zone.
Like I said in my edit to my last post, the final chapter is not written on his deal, but if he pitches this year like he did he did last year, we can call the time of death.
