It was the second straight win for Philadelphia, 8-2 against the Nationals this season. Washington has lost four straight to drop to 13-34.
Jimmy Rollins had two hits and two RBIs, Raul Ibanez, Jayson Werth, Pedro Feliz and Carlos Ruiz also each had two hits, and every Philadelphia position starter had at least one. The Phillies stranded 13 runners.
J.A. Happ (3-0), making his second start of the season and seventh of his career, went 5 1-3 innings and allowed three runs on three hits while matching his career high with five strikeouts. All three of the left-hander's wins — two in relief — this season are against the Nationals.
Brad Lidge pitched a scoreless ninth for his 10th save.
Ross Detwiler (0-1), making his third career start, gave up 10 hits and five runs in four innings. In his previous two starts, he allowed four runs (three earned) and five hits in 11 innings while holding batters to a .125 average. The Phillies had no such trouble against the rookie left-hander, especially in the third inning when they scored three runs on four hits.
Victorino led off with a single and went to third on Utley's double before Ibanez drove both home with a single. After the second out, Feliz tripled home Ibanez. Philadelphia scored the winning run in the fourth inning when Utley's groundout plated Rollins, who led off with his second double of the game. The run gave Philadelphia 5-1 lead, but Washington came back with three runs in the sixth. Josh Bard and Anderson Hernandez drove in runs in the inning for the Nationals.
Josh Willingham led off the second with a homer for Washington.
