Jon Heyman on SI.com reveals the Twins demands for Johan Santana.

The Yankees have been offering a package leading with Ian Kennedy and Melky Cabrera, however the Twins are insisting that Philip Hughes be included.

The Twins have requested Jacoby Ellsbury and Clay Buchholz from the Red Sox. The Red Sox seem unwilling to deal either player.

The Twins asked the Dodgers for Clayton Kershaw and Andre Ethier but they refused.

Buster Olney on his ESPN blog writes of the matters that could complicate the trading of Johan Santana.

Among them is his no-trade clause, which he could use as leverage to block any deal where he doesn’t feel he will get his best return on a new deal.

On top of that, a team would need to part with a number of their best prospects, a proposition that could present another roadblock due to the fact that the Yankees are reluctant to give up Joba Chamberlain, Ian Kennedy, and Phillip Hughes, and the Red Sox may be unwilling to trade Clay Buchholz, Jon Lester, and Jacoby Ellsbury on top of a $150 million contract extension.

The Mets seem more willing to deal their prospects, as Omar Minaya has stated that ‘nobody’s untouchable’ and he intends to upgrade his rotation this off season.

A package could include either Carlos Gomez, Fernando Martinez, or more likely Lastings Milledge, who has the most major league experience of the three, as the Twins want players who are major league ready in return, along with and pitchers Mike Pelfrey, Phil Humber and Joe Smith.

Hot Foot reported earlier this week that Jim Callis of Baseball America doesn’t believe the Mets could put a package together that the Twins would be willing to accept for Santana. Callis believes the Mets should set their sights on Dan Haren instead. Ken Davidoff seems to agree, and writes of a Haren deal with the Mets on Newsday.

“Trade Aaron Heilman, Lastings Milledge, Kevin Mulvey and a lower-level prospect to the A’s for Dan Haren.The beauty of a Haren trade is that the Mets would be acquiring an ace for the price of a back-of-the-rotation starter. They would retain the payroll flexibility to go out and get Santana on the free-agent market a year from now, if Santana is still available, or Erik Bedard in two years.”

Olney wonders if a package of Milledge, Humber and Pelfrey would be enough weighed against the backlash new Twins GM Billy Smith would receive from fans for trading Santana.

Smith, in his first year as Twins GM, will look to shape his legacy in his first season. He could find that he may endear himself better to fans, however unlikely, by holding onto Santana, hoping he leads the Twins back into the pennant race next season rather than hand him over to the Yankees or Red Sox.
