Buster Posey had his first multihomer game in nearly five years, Alex Dickerson and Wilmer Flores connected during a six-run eighth inning and the San Francisco Giants muscled past the Philadelphia Phillies 10-7 Tuesday night. Tommy La Stella also homered for San Francisco, which got all of its run via the long ball. The Giants have 25 homers through 17 games, a surprising surge for a club that's finished in the bottom third of the league in homers in eight of the past 10 seasons.
