The Yankees? pursuit of Johan Santana showed a flicker of life early Tuesday morning when the Minnesota Twins backed off their demand that the right-hander Ian Kennedy be added to the Yankees? trade offer. But with the Yankees? midnight deadline for a deal come and gone, the teams had still not reached an agreement on the third player to be added to the package of Phil Hughes and Melky Cabrera. If the sides cannot agree by Tuesday morning, the Yankees say they will back out of trade talks. ?If things don?t change drastically, it?ll probably be no,? the Senior Vice President Hank Steinbrenner said.
