LaMonte Wade Jr. belted two home runs and a double, Wilmer Flores triggered a three-run sixth inning with a homer and the host San Francisco Giants salvaged one of three from the last-place Pittsburgh Pirates with a 6-1 victory Sunday afternoon. Left-hander Alex Wood (9-3) combined with four relievers on a five-hitter to win his fourth straight decision, helping the Giants gather a bit of momentum with the rival Los Angeles Dodgers coming to town.
