Jeff Samardzija saved a depleted bullpen. The right-hander tossed three-hit ball over six scoreless innings, Buster Posey, Pablo Sandoval and Kevin Pillar homered in a five-run fifth and the short-handed San Francisco Giants beat the Philadelphia Phillies 5-1 Wednesday night. The Giants were down three relievers after a flurry of moves before the trade deadline but Samardzija (8-8) handcuffed Philadelphia for his fifth straight road win.
