WASHINGTON (AP) -- Cameron Rupp hit a tiebreaking, two-run double off Jonathan Papelbon in a three-run ninth inning, and the Philadelphia Phillies beat the Washington Nationals 3-0 Thursday to complete a three-game sweep.
Aaron Nola, Dalier Hinojosa, Elvis Araujo (1-0) and Jeanmar Gomez combined on a four-hitter and extended Washington's scoreless streak to 22 innings.
Philadelphia has won six of seven and at 12-10 moved two games over .500. The Phillies swept a series in Washington for the first time since May 2009.
Odubel Herrera singled off Felipe Rivero (0-1) opening the ninth and took third on Freddy Galvis' double.
Maikel Franco was walked intentionally, and Papelbon came in to strike out pinch-hitter Darin Ruf. Rupp hit a drive to deep right that landed over a backpedaling Bryce Harper at the warning track, and David Lough followed with a run-scoring single boosted the lead.
Gomez pitched a one-hit ninth for his seventh save in seven chances -- his third in three days -- getting Jayson Werth to ground into a game-ending double play.
In a game delayed by 36 minutes at the start because of rain, Harper went 1 for 4 on the fourth anniversary of his major league debut. The NL MVP struck out against Araujo with two outs and the bases loaded in the eighth.
Nola, 0-1 with a 7.80 ERA in three prior starts versus Washington, gave up two hits and struck out seven in seven innings.
Washington's Tanner Roark, who struck out a career-high 15 in his previous outing, fanned six as he yielded two hits over seven innings for his second straight start.
