From ESPN: The Mets have agreed to a trade with the Minnesota Twins to acquire Johan Santana for four prospects, pending the left-hander passing a physical and working out an extension with New York.
The Mets have been granted a 48- to 72-hour window to work out a new contract with Santana.
If New York can work out a contract agreement with Minnesota, the Mets will send outfielder Carlos Gomez and pitchers Phil Humber, Deolis Guerra and Kevin Mulvey to the Twins.
The trade agreement was first reported by USA Today on its Web site.
"Right now, the Twins have no comment," the Twins' head of communications, Mike Herman, told 1050 ESPN New York's Andrew Marchand. Mets vice president of media relations Jay Horwitz also had no comment.
Santana, who completely controls his fate because of the full no-trade clause he possesses, asked the Twins to make a decision, which is why Minnesota imposed a Tuesday deadline for offers from the interested teams.
