Zobrist would be a great fit for the Sox.
Two reasons the Rays entertain this - He's making $5.5M next season with a $7M option for 2014, i.e. getting priced out of their range for a secondary player and they need a cost-controlled power bat with Upton gone - which means Viciedo going the other way.
IMO, Viciedo alone wouldn't get a deal done for Zobrist, we'd probably have to throw in one of our OF prospects and/or a young reliever like Nate Jones.
The question for me is would the Sox risk Viciedo potentially equaling Zobrist's numbers in the near future - making the deal for a more refined and reliable hitter but one who's likely hitting FA in 1-2 more years?
If I were Hahn, I'd push for a younger player with more upside if they're thinking of dealing Viciedo.
