Until Boston makes a trade, Paplebon likely doesn't have a spot. The Red Sox rotation already has Beckett, Schilling, Wakefield, Wells, Clement, and Arroyo. Even with a trade, Papelbon likely needs an injury to crack that rotation. Heilman is also likely a bullpen arm. He'll be in the majors all year, but I don't see him in the rotation. I could be wrong there, though. Liriano will crack the Twins rotation some time this year; I'm not certain if he breaks camp with the club though.
