Luis Severino kept everybody warm on a blustery night by breaking out the heat early and maintaining it. 

When it wasn’t the four-seam fastball, the veteran right-hander was frustrating batters with his cutter. Overall, 72 percent of his 90 pitches were fastballs, and solid contact was a problem for the opposition. 

With Severino in command over his five innings, the Mets opened a new homestand with their fourth victory in five games, 6-1 over the Royals at Citi Field. 

“Going out there it was just about not trying to strike out everybody and getting quick outs,” Severino said. “Get some ground balls and try to attack the hitters.” 

The Mets spread around the offense, receiving big hits from Brandon Nimmo, Brett Baty and Pete Alonso. And Jeff McNeil, who began to emerge from his early slump over the last week, had a breakout 3-for-4 performance with an RBI. 

The only blemish on Severino’s night was the four walks that kept him from extending beyond the fifth.

But for a second straight start, he held an opponent to one earned run over five innings. On this night, the only hit he allowed was Salvador Perez’s homer leading off the second inning. 

“I was feeling good, I thought I was going to go back out there for the sixth, but Mendy told me I threw a lot of pitches last time and it was a long [fifth] inning,” Severino said, referring to manager Carlos Mendoza. “The main thing is, I’m healthy and I feel good and hopefully next time I will get through six.” 

Severino walked Adam Frazier on 12 pitches leading off the fifth. Makiel Garcia walked with two outs in the inning before Severino escaped by striking out Bobby Witt Jr. 

The Mets bullpen handled the rest, with Jake Diekman, Reed Garrett, Adam Ottavino and Jorge Lopez combining for four shutout innings. 

For Severino, it was a much better performance than his Citi debut in a Mets uniform.

In that game against the Brewers two weeks ago, he allowed a homer to Rhys Hoskins as part of an 11-hit beatdown over five innings in which he allowed three earned runs and six overall. 

Severino averaged 96 mph with his four-seamer on this night and 93.3 mph with his cutter.

He struck out four batters. 

“I think he did a good job attacking the zone,” Mendoza said. “I thought he was pulling pitches [early], but after that found a rhythm. I thought he was in position to go deeper in the game and then that fifth inning, that 12-pitch at-bat with Frazier, he had to work.” 

Perez homered leading off the second to put Severino in a 1-0 hole.

Severino walked consecutive batters, Nelson Velazquez and Frazier, later in the inning but escaped by retiring Hunter Renfroe and Kyle Isbel in succession. 

Nimmo’s RBI double in the third tied it 1-1 following Harrison Bader’s two-out single and stolen base against Michael Wacha. 

Four straight singles against Wacha in the fourth allowed the Mets to take a 3-1 lead.

After Alonso hit into a double play, Baty, Francisco Alvarez, McNeil and DJ Stewart each delivered a single, netting two runs. 

Baty’s two-run double off center fielder Isbel’s glove extended the Mets’ lead to 5-1 in the fifth.

Nimmo’s walk and a single by slumping Francisco Lindor set up the inning. 

Before his first plate appearance, the reeling Lindor received a standing ovation — following team owner Steve Cohen’s advice to fans in a tweet last weekend — but was retired.

Lindor also heard cheers before his ensuing at-bats on a night he finished 1-for-3 with a walk and single. 

Alonso smoked an 0-2 fastball from Will Smith for a homer leading off the seventh.

The blast was Alonso’s fourth of the season. 

“We are finding our footing,” Lindor said. “We are sticking with each other. We are playing the game the right way. We don’t have the team to go out there and roll through teams. There are times we lost games in one inning. The first week we lost a couple games in one inning. Now we are in a place where we are playing every inning the right way.”
