From Buster Olney:

Our colleague Peter Gammons is hearing that the Twins want this three-player package from the Yankees, in any Santana conversation: pitcher Phil Hughes and center fielders Melky Cabrera and Austin Jackson. Given that the Yankees will probably be asked to pay Santana a deal of at least six years and $150 million to convince him to stay, I'd be shocked if they seriously considered that trade. Because part of the equation for the Yankees or any other team, as they make decisions about a possible Santana deal, is this: Even beyond the question of swapping promising young players like Hughes and Cabrera and Jackson, how much money does it save them to have cheap players on their roster. How much will it cost them to replace a Cabrera or Jackson? Without Cabrera or Jackson, the Yankees might have to sign a veteran center fielder in their place in a year or two.
