According to Mr. Ken Rosenthal, the Mets want Burgos in exchange for a pitching prospect.  I have no idea which prospect the Mets plan on sending the Royals way.  I highly doubt Omar would be willing to offer a Mike Pelfrey, Phil Humber or Miguel Pinango for Burgos.  I wouldn't be surprised to see them send Adam Bostick and Jason Vargas (who were just acquired from Florida) to Kansas City.
