Rapid Reaction: Mets 5, Nats 2

WASHINGTON -- Juan Lagares will be in the lineup on Sunday. Promise.

Lagares homered and drove in three runs and also took away a homer from Jayson Werth as the Mets beat the Washington Nationals, 5-2, Saturday.

Jenrry Mejia, despite surrendering a leadoff single, tossed a scoreless ninth for his first save since June 15, 2007, in the Dominican Summer League.

The Mets (20-22) snapped a streak of nine straight losses against Washington. The franchise record for losses against a single team remains 12, against the Braves in 1962-63.

Juan Lagares receives congratulations after returning to the dugout following his two-run homer in the third.Lagares (2-for-4) had been out of the starting lineup the previous three games, as Terry Collins opted for an outfield configuration he felt had more offensive potential with the Mets struggling to score runs.

Eric Campbell (2-for-4) had a two-run single and Lagares followed with an RBI single in a three-run first against Nats left-hander Gio Gonzalez. Two innings later, Lagares belted a two-run homer as the Mets opened a 5-0 lead.

Gonzalez was pulled after three innings in his shortest start since Sept. 14, 2010. Craig Stammen followed with four scoreless innings, during which he limited the Mets to one hit.

Ian Desmond produced a two-run homer in the fourth against Bartolo Colon. Lagares helped prevent Washington from drawing closer.

Werth, who took away a potential game-tying homer from Daniel Murphy in the series opener, had the tables turned Saturday. Lagares leaped at the center-field wall and brought back a would-be solo homer from Werth in the sixth.

Benefiting from Lagares’ catch, Colon retired the final 11 batters he faced. His final line in a 105-pitch effort: 8 IP, 5 H, 2 R, 2 ER, 1 BB, 5 K, 1 HR. Colon stranded runners in scoring position in three different innings. He earned his first win since April 24.

What’s next: Zack Wheeler (1-3, 4.53 ERA) looks to get back on track when he opposes right-hander Jordan Zimmermann (2-1, 3.59) in Sunday’s 1:35 p.m. rubber game. Wheeler allowed five runs in a career-high 118-pitch effort that lasted only 4 1/3 innings Tuesday in the Bronx.
