Hunter Pence, Pablo Sandoval and the San Francisco Giants charged back at a pulsating AT&T Park, taking a 7-4 lead over the Kansas City Royals through six innings Saturday in Game 4 of the World Series. Trailing 2-1 in the Series and in danger of dropping into a huge hole, the Giants and their fans rallied. All the early frustration that prompted manager Bruce Bochy to throw his hat in the dugout turned into positive energy during a two-run comeback in the fifth that made it 4-all. Then in the sixth, Sandoval hit a two-run single and Brandon Belt followed with an RBI single as the Giants roughed up postseason darling Brandon Finnegan to surge ahead.
