Roark, Werth lead Nationals past Phillies 4-0

PHILADELPHIA -- 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.

Thompson settled in nicely after a rough start. His last pitch was a nasty curve that froze Turner for strike three.

Roark didn't need much support. The righty stifled the Phillies again. He's 3-0 with a 0.64 ERA against them this season.

The NL East-leading Nationals snapped a two-game losing streak.

DIVISION DOMINANCE

Washington is 36-16 against the rest of the NL East. It's the best division record in the majors.

ROSTER MOVES

OF Michael A. Taylor was recalled from Triple-A Syracuse by the Nationals. RHP Lucas Giolito was optioned down.

ODUBEL ON THE MOVE

Phillies All-Star CF Odubel Herrera will likely play a corner outfield spot in winter ball. Manager Pete Mackanin has been impressed with Aaron Altherr in center and prospect Roman Quinn also plays there.

TRAINER'S ROOM

Nationals: RHP Stephen Strasburg threw a bullpen session one week after he was placed on the DL with elbow soreness. Strasburg is expected to return to the rotation when he's eligible.

UP NEXT
