WASHINGTON -- Daniel Murphy drove in five runs on four hits, Bryce Harper had three hits and two RBIs and the Washington Nationals routed the New York Mets 11-4 on Tuesday.
Murphy improved his career average to .405 against the Mets, his first and only former big league team. This was the third straight victory for NL East-leading Washington.
Joe Ross (5-3) allowed two runs over seven innings for the Nationals in his fourth consecutive start giving up two runs or fewer.
New York's Seth Lugo (3-2) yielded four of his sixth runs in his fifth and final innings, and failed to pitch beyond the fifth for the first time since his return from injury in June.
Jay Bruce hit his 21st home run for New York in the ninth. Jose Reyes and Rene Rivera also homered and Brandon Nimmo had three hits, but the Mets left nine men on and finished 0 for 4 with runners in scoring position.
In his fifth start after missing two months with elbow inflammation, Lugo required eight pitches to retire Washington's first five batters. But he eventually walked two and allowed 10 hits, including five straight to open the fifth.
Wilmer Difo singled and scored from first on Bruce's error fielding Harper's single to right. Harper raced to third and scored on Murphy's second single of the game. Two batters later, Ryan Raburn doubled in two runs to make it 6-2.
Murphy drove in two more on a single into shallow right, after relievers Erik Goeddel and Josh Edgin loaded the bases on three consecutive walks, making it 8-2.
Ross allowed eight hits, walked three and let multiple baserunners reach in each of the first five innings. He finally pitched a clean inning in the seventh and finished throwing 114 pitches, his last one a sinking changeup to strike out Lucas Duda on an eight-pitch at-bat.
