Before his MLB debut on Friday at Citi Field, Ronny Mauricio said through an interpreter he wanted to “go out there and put on a show.” 

The switch-hitter, called up from Triple-A Syracuse on Friday, opened the show in the Mets 2-1 win over Seattle, ripping a 117.3-mph double to right from the left side to lead off the bottom of the third in his first at-bat. 

It was the hardest-hit ball by a Met this season and the 11th hardest-hit ball in the majors all year. 

Mauricio said he had never hit a ball that hard. 

“It was incredible it happened in that moment,’’ said Mauricio, who had about 20 family members and friends in attendance. 

And the 22-year-old also proved to be capable at second base — the position he started playing this season in the minors. 

He caught the first ball hit in his direction, a routine popup by Dominic Canzone to end the top of the second, and then started a 4-6-3 double play on a Mike Ford grounder an inning later. 

“He turned a good double play and [made a] good feed,’’ manager Buck Showalter said, noting Mauricio’s other routine plays at second. “That’s what stuck out to me.” 

“This is what I always wanted and what I’ve prepared myself for,” Mauricio said.

“Now I’m here, and I have to go out and play without fear.” 

Mauricio was joined by Brett Baty, back in the majors after a nearly monthlong stint with Syracuse after his rookie struggles.

Baty snapped an 0-for-21 streak, after a pair of strikeouts, with a seventh-inning single. 

The Mets expect to use the final month of a lost regular season looking at Mauricio’s ability to play in the majors, as well as how Baty and fellow rookies Francisco Alvarez and Mark Vientos finish the year. 

“We grew up together, pretty much, in the system and I think that’s the goal for all of us,” Mauricio said, “to be a part of this core.” 

Mauricio began the season at his regular spot at shortstop before being shifted initially to second base and then left field. He’s also started a pair of games at third base. 

Showalter said Mauricio’s position would be decided on a daily basis, based on conversations with general manager Billy Eppler and the needs of the teams. 

“No one can say for sure if and where he might be down the road,’’ Showalter said. “He’s got experience at four [positions] this year and all four are on the table. A certain part of this is we’ve got to be fair to the people competing against Seattle and also do what’s best for the Mets.” 

Mauricio said he didn’t know where he’d end up playing defensively and acknowledged getting used to playing both second base and left field has been “difficult.” 

“It’s an adjustment period, but I’m starting to feel comfortable,’’ Mauricio said. “I still have a lot to learn at second base with my footwork.” 

Baty found himself back in Queens after he was being sent down after going 0-for-18 with eight strikeouts in his last six games with the Mets in early August. 

“It was a good break,” Baty said of the demotion. “Just go down there and work on some things and get back to being who I am.” 

Baty said by the end of his earlier stint with the Mets, he “started to do too much and that’s not who I am. I just need to hit balls hard up the middle. I kind of got away from that a little bit and hopefully I get back on track.” 

And he added that his issues at third base stemmed from trying to “make every single play and be perfect.” 

He wasn’t tested on Friday and Showalter said Baty still has to prove himself at this level. 

“We’ll see,’’ Showalter said. “Brett is very capable. We’ve seen it. I’d love to see him finish strong if the game will allow it.

“He’s gonna face some really good pitching.”
