Giants ride sixth-inning rally to 3-1 NLCS edge

Buster Posey went 2-for-3 and drove in three runs to lead the Giants to a 6-4 triumph Wednesday night over St. Louis in Game 4 of the National League Championship Series. A three-run rally in the sixth inning, which included a clutch RBI single from Posey, put the Giants on top after they had trailed since the second inning.
