For the second year in a row, Giancarlo Stanton's chances of winning the major league home run title have been hurt by an injury. The Miami Marlins slugger has a broken left hand, which is expected to sideline him four to six weeks. Stanton, who grimaced as he swung and missed for strike three Friday night in the ninth inning of the Marlins' 7-1 loss to the Los Angeles Dodgers, said the injury became worse as the game progressed.
