PHILADELPHIA, Sept. 22 (UPI) -- Michael Morse hit a three-run homer Thursday and six Washington pitchers combined to throw a four-hitter in bringing the Nationals a 6-1 win over Philadelphia.
Washington completed a four-game sweep of the Phillies, who have lost six in a row since clinching their fifth straight National League East title. Philadelphia remains two wins shy of reaching 100 for the season.
Brad Peacock (2-0), a winner in both his major league starts, allowed one hit over 5 2/3 scoreless innings.
Morse hit his home run during a four-run eighth that gave Washington a 6-0 lead. Ian Desmond doubled home a run in both the third and eighth.
Roy Oswalt (8-10) gave up all six runs on seven hits over 7 2/3 to take the loss. It was Philadelphia's final home game of the regular season.
