WASHINGTON — The opponents on this road trip aren’t particularly daunting, giving the Mets a wide opening to continue their recent surge.

Monday night they avoided a letdown following the euphoria of winning the Subway Series, attacking throughout against the Nationals.

‘The Mets won 16-7 in 12 innings for a sixth victory in seven games.

The Mets scored 10 runs in the final inning, piling on against Jorbit Vivas, a position player, after they had built a comfortable cushion.

“When you win games, you start to kind of feel what it feels like, and you just try to keep that going,” Bo Bichette said. “It’s fun to win. It’s fun to come to the park right now.”

Carson Benge’s RBI single in the 12th inning brought in the go-ahead run after Hayden Senger’s sacrifice bunt had advanced the automatic runner.

Vidal Bruján’s suicide squeeze brought in Benge for an insurance run.

Brett Baty delivered the dagger with a two-run single.

But the Mets kept going. Marcus Semien, A.J. Ewing, Benge and Bichette all had hits that brought in runs to complete the onslaught in the inning.

“It was back and forth, and we never got down,” manager Carlos Mendoza said. “We kept punching, and even when we didn’t score in a couple of extra innings there, the pitching staff gave us a chance and the guys came through.”

Huascar Brazobán survived the 10th and 11th innings.

After Joey Wiemer’s infield hit in the 11th brought in a run to tie it 6-6, Baty at first base executed a tight throw on a grounder to nail the lead runner Wiemer at second.

The ensuing batter, Vivas, doubled, but the Nationals never scored the winning run.

“I was just trying to turn a double play there and [the throw] snuck by Wiemer,” Baty said. “I was just trying to get two outs there.”

Home runs by Baty and Bichette were the hits that resonated the loudest, but Tyrone Taylor, Juan Soto, Benge and Luis Torrens all were instrumental offensively on a night the Mets rallied from a 3-2 deficit in the middle innings.

The Mets carried a 5-3 lead into the seventh, but couldn’t hold it.

After Brooks Raley surrendered a run in the seventh, Tobias Myers allowed an RBI double to Curtis Mead in the eighth that tied it.

Myers had recorded a big out an inning earlier, entering with the bases loaded to strike out José Tena.

The Mets (21-26) play another three games against the Nats before heading to Miami for three this weekend.

Christian Scott had a third straight start in which he failed to pitch at least five innings.

The right-hander was removed after allowing three earned runs on four hits and three walks with five strikeouts over four innings.

He threw 81 pitches.

“In order to get deeper in games, I have to get ahead and stay ahead,” Scott said.

Torrens’ RBI double in the second gave the Mets a 1-0 lead.

The run was unearned after Taylor singled and advanced two bases on James Wood’s double error.

Wood misplayed the ball and then overthrew second attempting to nail Taylor.

Scott got two fast outs in the bottom of the frame before drilling Jacob Young in the ribs (Young departed the game).

Tena’s RBI double tied it, and Drew Millas’ single — following a walk to Vivas — put the Nats ahead 2-1.

Scott encountered additional heavy traffic in the third and allowed another run on Wiemer’s RBI double.

Brady House singled to begin the rally and Daylen Lile walked with two outs.

Lile stumbled rounding third base on Wiemer’s double and had to retreat, potentially costing the Nats a run as Scott retired the ensuing batter, Tena, for the third out.

Baty’s homer leading off the fourth pulled the Mets to within 3-2.

It was the third homer this season for Baty, who crushed Jake Irvin’s first-pitch sinker 451 feet to center field.

The Mets rallied in the fifth to take a 4-3 lead.

Torrens reached on an error by first baseman Luis García Jr. and Benge walked — both runners advanced on Bichette’s flyout — before Soto stroked a two-run single.

Bichette’s homer in the seventh widened the Mets lead to 5-3.

It was a needed contribution for Bichette, who began the day with a paltry .531 OPS.

“I’m pretty sure he’s going to get going here,” Mendoza said. “And he’s going to carry us for quite a bit.”
