After weeks of speculation that the Yankees and Red Sox were the two favorites to land Johan Santana, the Twins could wind up shipping him to the Mets. According to people with knowledge of the discussions, the Mets have offered top pitching prospect Deolis Guerra, along with center fielder Carlos Gomez and pitchers Kevin Mulvey and Phil Humber. The Twins like those players. They've told the Mets they'd have a done deal if New York would add prized outfield prospect Fernando Martinez.
