I'm pretty sure if they traded for another starter that would mean one of Milone, Pelfrey, Gibson etc would be traded as well (which could help fill another position) As long as the price would be right, they should be looking to upgrade. If I was running the show, I think my top targets for a trade candidate would be David Ortiz (solves your LH bat and DH problem), and one of Pappelbon, Clippard or Chapman to help build a shut down pen. I would also buy low on an Ian Desmond type as well to fill in at SS. CF I wouldn't touch, Rosario is fine there for now and Buxton/Hicks both will be back within a month.
