Susan Slusser of the San Francisco Chronicle reports that the Blue Jays are interested in trading for Athletics left-hander Gio Gonzalez. The 26-year-old southpaw has, not surprisingly, draw significant interest from around the league. But, A's general manager Billy Beane will be asking for a large package of prospects for him, as Gonzalez is still relatively cheap for the time being since he's arbitration-eligible for the first time this winter. The Nationals, Tigers, Diamondbacks, Royals, Marlins, Reds and Yankees have all expressed some interest in the lefty.
