While reminiscing about old Shea Stadium, Johnson switched to the present, saying: "It would make my day if we sweep them here—it would make my year."

And the Nationals obliged, with another power display.

It was all or nothing for the Nationals against Harang until Bryce Harper singled to center with two outs in the sixth. Harang gave up only the three homers and struck out 10 before Harper's hit. Span was the only Nationals player that spent any time on the bases—he walked with one out in the third.

"I thought he threw good. He moved the ball around, struck out guys. The way they're swinging, that's hard to do and I thought he did a very good job," Collins said. "They hit three homers, but they're hitting homers all the time."

Zimmerman connected for the eighth time in 10 games with one out in the first, a drive to straightaway center. The Mets evened the score on Daniel Murphy's RBI double in the bottom half.

After a rain delay of 56 minutes, LaRoche hit a drive to left-center that Eric Young Jr. appeared to knock back into play with a leap at the wall. But after a video review of more than three minutes, umpires ruled a home run that gave Washington a 2-1 lead. It was LaRoche's fourth homer in 32 at-bats against Harang.

New York tied it again on Anthony Recker's RBI single to left field in the fourth. The Mets might've run themselves out of a big inning when Mike Baxter was thrown out trying to advance to third on the play.

"You play a team as good as they are, you gotta do the little things right," Collins said. "And we didn't do very many little things right."

Ramos homered leading off the fifth to put Washington ahead for good. After Recker's hit, Roark retired seven of his final eight batters.

New York had runners on second and third in the seventh but Craig Stammen struck out Juan Lagares to end the chance. Rendon hit a sacrifice fly in the seventh and homered in the ninth.
