Roark, Werth lead Nationals past Phillies 4-0
PHILADELPHIA (AP) Tanner Roark threw seven impressive innings, Jayson Werth hit a solo homer and the Washington Nationals beat the Philadelphia Phillies 4-0 on Monday night.
Roark (14-7) allowed four singles and struck out five. Marc Rzepczynski tossed a perfect eighth and Mark Melancon finished off the four-hitter.
Phillies rookie Jake Thompson (1-4) allowed two runs and seven hits in seven innings. It was the longest and best of his five career starts.
Werth lined a solo shot to left in the first against his former team. A member of Philadelphia's 2008 World Series championship team, Werth was greeted by boos, as usual.
Bryce Harper raced home from first on Anthony Rendon's single to left-center to make it 2-0 in the first. Clint Robinson and Trea Turner had RBI singles off Frank Herrmann in the ninth.
