Buster Olney of ESPN.com reports that the Athletics are "moving closer" to trading left-hander Gio Gonzalez. Olney hears that the bidding is down to two teams and confirms that the Nationals are one of them. He speculates that the Red Sox or Marlins could be the other. Gonzalez, 26, is under team control through 2015, so the asking price is expected to be substantial. Bill Ladson of MLB.com reported Wednesday that the Nationals were talking about a package which included right-hander Brad Peacock and prospect catcher Derek Norris.
