The Twins want to (and need to) aquire a #2 starter this off season. However, I'm skeptical that they'll be able to do so with Polanco and/or Kepler being the key pieces. I think it would require two things:
1. A willing trade partner: not sure many teams are looking to trade away SPs and if they are, the Twins will be competing with several teams to aquire meet a team's astronomical price for one, and;
2. Trading away elite prospects like Lee or Rodriguez.
As for this Baltimore pitcher, like others, I don't see why Baltimore would trade him unless someone overpays.
