Consecutive road losses have become something of an anomaly for the Philadelphia Phillies.

The team with the major's best record shook off a ninth-inning collapse in Friday's series opener to shut down the Washington Nationals, 5-0.

Jimmy Rollins and Wilson Valdez both knocked in two runs for the Phillies, who established a franchise record by going 31 games without back-to-back losses as the visiting club. Philadelphia hasn't dropped two straight on the road since a four-game slide from May 31-June 4.

Roy Oswalt (6-7) took the mound for the second straight Saturday against Washington after an extended rain delay at the outset of Friday's game forced his start to be pushed back. The right-hander gave up eight hits, walked one and recorded nine strikeouts over eight innings. The strikeout total and innings pitched were both season-highs.
