According to Joe Frisaro of MLB.com, the Marlins aren't convinced the Athletics are willing to part with Gio Gonzalez. The Marlins are willing to part with prospects and big-league talent in order to upgrade their rotation this winter, but the Athletics will ask for a huge return since Gonzalez is under team control through 2015. Miami doesn't have much in the way of top prospects, so any deal would likely need to be centered around Logan Morrison.
