The San Francisco Giants have jumped out to a 1-0 lead in the best-of-seven National League Championship Series, riding two key Cody Ross home runs as well as strong pitching from Tin Lincecum and two relievers to a 4-3 victory in Philadelphia.

The Phillies’ ace Roy Halladay took a step back from his no hit performance in the NLDS against the Cincinnati Reds, surrendering 4 runs in 7 innings of work.

Pat Burrell drove in a run with a two-run double, as did Juan Uribe, who chipped in an RBI single for the visiting Giants.

San Francisco will send left handed starter Jonathan Sanchez to the mound in Game 2, and he’ll go up against mid-season import Roy Oswalt for the Phillies, who will be looking to even the series at 1 before heading to San Francisco.
