Game in a nutshell: A prime pitching matchup between Jordan Zimmermann and R.A. Dickey lived up to the billing; even though Zimmermann labored through much of his five innings, he managed to allow only two runs and keep the game close. Dickey, meanwhile, thoroughly dominated the Nationals through six innings, his only blemish to that point a manufactured first-inning run. But then Tyler Moore came up to pinch-hit in the top of the seventh and crushed a game-turning homer, giving the Nats the lead. Kurt Suzuki and Bryce Harper (career-high four hits) plated a couple of big insurance run in the top of the ninths, and a pieced-together bullpen of Tom Gorzelanny, Christian Garcia, Michael Gonzalez, Drew Storen and Tyler Clippard finished off the Nationals' 88th win of the season (though Clippard allowed a solo homer to Scott Hairston in the bottom of the ninth). At this moment, the Nationals lead the NL East by 7 games, the NL wild card by 13 12 games, with 20 to play.
Hitting highlight: It's been tough for Davey Johnson to find at-bats for Moore since Jayson Werth and Michael Morse came back from early season injuries, but the rookie is somehow finding a way to keep his bat hot despite the lack of action. He stepped to the plate in the top of the seventh inning tonight to pinch-hit for Gorzelanny and wasted no time inflicting damage on Dickey, crushing the first knuckleball he saw into the left field stands. That's nine homers this season for Moore in only 138 at-bats. Do the math: Over a full season, that's quite impressive.
Pitching highlight: While Zimmermann labored through his five innings, Garcia absolutely dominated his one inning of relief. Despite this being only his fifth big-league appearance, the right-hander was entrusted with a one-run lead in the bottom of the seventh, a major vote of confidence from Johnson. Well, Garcia earned even more with his explosive performance. He struck out the side, showing both a high-90s fastball with a devastating changeup and slider. In only 4 23 innings, he's already got seven strikeouts and zero walks. Could a rookie September call-up force his way onto the October playoff roster? It's happened before (remember Francisco Rodriguez with the Angels in 2002?). If Garcia keeps this up, he's going to have a strong case for it.
Key stat: In 32 career plate appearances against Dickey, Werth now has 13 hits and five walks. That equates to a .563 on-base percentage.
Up next: The series wraps up at 7:10 p.m. Wednesday, with New York native John Lannan officially taking over Stephen Strasburg's spot in the Nationals' rotation. Lannan will face Mets rookie Matt Harvey, their top pitching prospect.
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.
