I think that even if we move both Buchholz and Kelly to the pen, we may still need to pick up another late inning bullpen arm. Uehara has durability concerns and Farrell seems intent on using him as much as possible. + do we really want to see guys like Hembree and Buchholz pitching in 1 run/tied games late, like we had today?
Not a knock on Hembree, I actually like him, but I just don't think he's more then a solid middle reliever.
