NEW YORK — Ronny Mauricio was ready for the moment.

A day after he was called up from Triple-A Syracuse, Mauricio delivered a pinch-hit, walk-off single in the 10th inning of the Mets’ 4-3 win over the Arizona Diamondbacks at Citi Field.

It was the first-ever walk-off RBI for Mauricio, who lined an 0-2 pitch from Paul Sewald to the right-field wall in his first MLB at-bat of the year.

The Mets brought up Mauricio to fill the roster spot vacated by Juan Soto, who landed on the injured list Monday due to a right calf strain.

That came after the Mets (7-4) tied the game in the eighth, when Jared Young lifted a sacrifice fly against former Yankees right-hander Jonathan Loáisiga to make it a 3-3 game.

The lefty-swinging Young, who had three hits in Sunday’s 5-2 in San Francisco, pinch hit for righty-swinging Mark Vientos, who is batting .417 this season but went 0 for 3 on Tuesday.

Arizona had taken a 3-2 lead with a three-run rally in the fifth.

With two outs and the bases loaded, Mets reliever Huascar Brazobán dotted a sinker just off of the plate.

Home-plate umpire Brian O’Nora rang up Arizona Diamondbacks designated hitter Adrian Del Castillo with a called third strike, seemingly ending the inning and preserving a two-run Mets lead.

But Del Castillo challenged the strike call, and an ABS review determined the pitch was a mere 3/10 of an inch off the plate.

That extended the inning, and the Diamondbacks took advantage. On Brazobán’s very next pitch after the overturn, Del Castillo lined a change-up into right field for a two-run single, tying the game, 2-2.

Nolan Arenado followed with a bloop RBI double that put Arizona ahead.

All three runs were charged to Mets starter Freddy Peralta, whose afternoon quickly unraveled. After hurling four scoreless innings, Peralta recorded the first two outs of the fifth with back-to-back strikeouts.

But Peralta surrendered a single to Corbin Carroll, walked Geraldo Perdomo and plunked Gabriel Moreno to load the bases before giving way to Brazobán.

Five consecutive D-Backs batters reached base with two outs during that three-run eruption.

That made Del Castillo’s successful appeal one of the most consequential overturns since MLB introduced its first-ever automated ball-strike (ABS) challenge system at the start of the season.

Peralta’s final line was 4 2/3 innings, three earned runs, three hits, three walks and five strikeouts on 101 pitches.

He threw at least 20 pitches in four different innings, including 27 before he was removed in the fifth.

Acquired in an offseason blockbuster trade with the Milwaukee Brewers, Peralta has a 4.80 ERA through three starts with the Mets. The right-hander went 17-6 with a 2.70 ERA last season, when he finished fifth in National League Cy Young Award voting.

Due to a frigid forecast and windy conditions, the Mets moved up the start times for Tuesday and Wednesday’s games by three hours to 4:10 p.m.

Despite the cold, the Mets’ offense got off to a hot start Tuesday, scoring a run apiece in the first and second innings against Arizona ace Zac Gallen.

Francisco Lindor delivered a hit in both innings, including a run-scoring two-out double in the bottom of the second.

Francisco Alvarez scored from first on that double, appearing to blow through third-base coach Tim Leiper’s stop sign as he surged home. Lindor was not credited with an RBI, however, as the right fielder Carroll was charged with a throwing error on the play.

Lindor had entered the game in a 2-for-25 skid, including going 0 for 10 with three strikeouts in the previous games.
