Game in a nutshell: Stop us if you've heard this one before: Jordan Zimmermann pitches brilliantly but gets precious little run support and finds himself facing a possible no-decision. Thankfully for the hard-luck right-hander, the Nationals strung together enough hits late to give him the lead. And Zimmermann didn't need much, because he didn't allow any runs over six strong innings. Adam LaRoche provided the big blast: a two-run homer in the sixth to snap a scoreless tie. Steve Lombardozzi then added the insurance knock: a two-run double in the seventh. That gave some cushion to the Nats bullpen, which unlike last night managed to close this one out in regulation (though Tyler Clippard did give up homers to both David Wright and Jason Bay in the ninth). Thus, the Nationals handed the Mets their sixth straight loss and dropped them eight games back in the NL East.
Hitting highlight: No, he's not raking at the plate the way he did during the season's first six weeks when he looked like a candidate for National League MVP. But LaRoche continues to come through with clutch hits on a regular basis for the Nats. The veteran first baseman delivered big-time in the sixth inning tonight, belting a 1-2 pitch from Chris Young into the Red Porch for his 16th homer and 54th and 55th RBI of the season. This may not turn out to be a career year for LaRoche, but he's basically doing exactly what the Nationals wanted him to do all along: Provide power, clutch hits and smooth defense at first base.
Pitching highlight: Just another quality start for "Mr. Consistency." Zimmermann was at it again, churning out six more scoreless innings and plowing through the Mets lineup with relative ease. He allowed only four hits, didn't walk a batter and in the process lowered his ERA to 2.35. That now ranks fifth in the majors. Perhaps most impressively, Zimmermann is getting better and stronger as this season plays out. Remember how the opposite seemed to be true last year as he made his comeback from Tommy John surgery? This is why the Nats limited him to 160 innings, and it's why they'll do the same with Stephen Strasburg later this season. You can't dispute the positive effect it's had on Zimmermann in 2012.
Key stat: Though he finally got his run support in the sixth, Zimmermann did go into the fifth inning without his teammates having plated a single run. That's the seventh time this season that's happened to the right-hander.
Up next: The series concludes with a fantastic showdown of the NL's only two 12-game winners: Gio Gonzalez and R.A. Dickey. They'll square off in Thursday's 12:35 p.m. matinee at Nationals Park.
WASHINGTON -- Anthony Rendon homered twice and drove in five runs, Joe Ross returned from the minors to allow one run over a career high-tying eight innings, and the Washington Nationals routed the Seattle Mariners 10-1 on Tuesday night.
Bryce Harper added his 14th homer and Jayson Werth hit his seventh off Chris Bergman (1-2), who allowed all of the Nationals' runs and 14 of their 15 hits.
Rendon doubled before his second homer -- and seventh of the season -- completed an eight-run fourth inning. Ryan Zimmerman also had three hits.
Mike Zunino homered off Ross (2-0) in his return from his own minor league stint. Robinson Cano was hitless in his first game back from the disabled list following a thigh injury as Seattle dropped its fourth straight.
Ross showed no signs of the late April struggles that ended with a demotion to Triple-A Syracuse. He yielded five hits and a walk while striking out six, and retired 12 straight batters after a leadoff single to begin the game.
By the time Seattle finally put multiple runners aboard, Washington had already opened a 10-0 lead.
Rendon's second-inning shot around the left field foul pole made it 2-0.
Then Werth, Harper and Rendon all connected in the fourth, helping the Nationals score seven of their eight runs in the inning with two outs.

The Nationals had a big day at the plate Tuesday night.
Washington hit four home runs, including three in an eight-run fourth inning, in its 10-1 victory over the Seattle Mariners.
Third baseman Anthony Rendon hit two home runs – the first a two-run blast to left field in the second inning and the second a three-run shot to center in the fourth. He finished the game 3-for-4 with five RBIs.
Prior to Rendon’s second homer in the fourth inning, left fielder Jayson Werth hit a two-run blast to left field, which was followed by a solo shot from right fielder Bryce Harper in the next at-bat.
Harper’s homer was measured at 450 feet.
At the end of the fourth, the Nationals led 10-0, which also included an RBI single from catcher Matt Wieters and an RBI triple from shortstop Trea Turner.
Tuesday night’s contest was the first of a three-game home series against the Mariners, who play in the American League. The Nationals and Mariners also will play Wednesday and Thursday.
Earlier this season in a 23-5 win over the New York Mets on April 30, Rendon went 6-for-6 with three home runs and 10 RBIs to become the first player to accomplish that feat since at least 1913. He now has seven homers this season.
Harper’s homer was his 14th of the season, tying him for first in the National League with the Atlanta Braves’ Freddie Freeman. The New York Yankees’ Aaron Judge is first with 15.
Though he did not have a home run Tuesday night, Nationals first baseman Ryan Zimmerman has 13 for the season.
