If the Yankees lose Alex Rodriguez ? whose agent, Scott Boras, says they should be open to negotiating with him as a free agent ? Miguel Cabrera would be an obvious target if the Marlins offered him. The Yankees have deepened their farm system, and pitchers Joba Chamberlain, Philip Hughes, Ian Kennedy and Alan Horne were off-limits at the July trading deadline. Trading for a player of Cabrera's caliber, though, would probably require the Yankees to change that stance and to consider moving young position players like second baseman Robinson Can? and center fielder Melky Cabrera. That seems unlikely, but the idea of using Melky Cabrera as a trading chip is intriguing because of the choices among free-agent center fielders: Torii Hunter, Andruw Jones and Aaron Rowand are all right-handed hitters who play outstanding defense.
