Jose Fernandez's comeback required a comeback. The precocious right-hander shook off a rocky start in his return from Tommy John surgery, pitching six innings and hitting a homer Thursday to help the Miami Marlins rally past the San Francisco Giants 5-4 and complete a three-game sweep. The first two batters to face Fernandez scored, and he screamed at himself as he walked off the mound to end the first inning.
