NEW YORK (AP) -- An agitated Stephen Strasburg settled down in a hurry after a rocky start and the Washington Nationals became the first visiting team to win at Citi Field this season, beating the New York Mets 8-2 on Thursday night.
The Mets had opened 10-0 at home for a team record-tying 12-game streak over two seasons.
Washington took advantage of yet another error by shaky shortstop Wilmer Flores to rally for its third straight win, matching its longest streak this year. Bryce Harper hit two doubles, including a three-run drive in the ninth inning.
Strasburg (2-2) seemed out of sorts at the beginning. In his previous outing, a loss at Miami, he got into a pointed discussion on the bench with pitching coach Steve McCatty.
This time, Strasburg strayed to talk with plate umpire Tom Hallion following the first inning after a few close pitches were called balls. In the second, Strasburg gave up consecutive doubles by Flores and Kevin Plawecki and glared at catcher Wilson Ramos.
Ramos briefly went to the mound, and then zipped the ball back to Strasburg after a pitch. When Curtis Granderson hit an RBI single, Strasburg didn't back up the throw home.
That prompted a visit from McCatty, and they sat next to each other in the dugout when the inning was over. Strasburg flipped his hand a time or two, apparently miffed.
But when Strasburg came out for the third inning, he was a completely different pitcher. He wound up retiring 10 straight before getting pulled after his 100th pitch as the Mets threatened in the sixth.
Strasburg gave up two runs and six hits in 5 1-3 innings, striking out seven.
Jacob deGrom (2-3) was perfect through three innings. He issued a leadoff walk in the fourth and Yunel Escobar followed with a routine double-play grounder, but Flores fumbled it for his sixth error this year.
Jayson Werth's single, Ryan Zimmerman's sacrifice fly and Ramos' RBI grounder put Washington ahead. Harper's double in the sixth set up RBI singles by Zimmerman and Ramos.
DeGrom allowed five hits and three earned runs in 5 1-3 innings.
Harper has reached base in a career-best 16 straight games. Nats center fielder Denard Span, on the disabled list earlier this year, left in the sixth and there was no reason given.
Washington reliever Sammy Solis made his big league debut, pitching two perfect innings.
Nationals: INF Anthony Rendon (left knee) had a full workout in the minors after missing several games because of tightness in his side. If he's OK, he's expected to play five innings for Double-A Harrisburg on Friday, manager Matt Williams said.
Mets: 3B David Wright, out since April 15 with a strained right hamstring, is "making progress," manager Terry Collins said. There's no timetable for him rejoining the team. ... RHP Rafael Montero will probably go on the DL because of stiffness behind his pitching shoulder, Collins said. Montero was brought up from Triple-A to start Tuesday and sent back to the minors after the game.
An ace matchup Friday night when RHP Max Scherzer (1-2, 1.26 ERA) returns to the Washington rotation to face RHP Matt Harvey (4-0, 3.04). Scherzer missed his last scheduled start after jamming his right thumb while batting. "I hope that thumb bothers him a little bit," Collins kidded. Harvey shut down the Nationals earlier this season and "is back to full force," Williams said. Harper is 0 for 10 with five strikeouts lifetime vs. Harvey.
