The Twins best trade bait right now is Glenn Perkins, Josh Willingham, and Justin Morneau and trading any of those 3 would be punting 2013 which is why a trade with the Blue Jays wouldn't fit. Toronto's not going to trade any of the top-4 you listed because they're trying to win now and none of the rest align with our 2014-2015 prospects. IF the Twins trade Perkins, Willingham, and/or Morneau I'd hope they'd continue to acquire pitchers in the mold of Meyer and May. For example, the Mariners, Braves, and Rangers all have top pitching prospects that fit into our 2014-2015 group that we should acquire.
Given the history of injuries and ineffectiveness the Blue Jays would need to keep all of their pitchers.
