The Yankees spent the weekend beating up on the Royals in a get-right series.

The Mets came into town on Tuesday and turned the tables.

Justin Verlander cruised through six shutout innings and Pete Alonso crushed a pair of home runs to lead the Mets to a 9-3 win over the Yankees in front of 46,540 at Yankee Stadium.

With the second edition of this year’s Subway Series beginning one week ahead of MLB’s trade deadline — and neither team looking like a surefire buyer — the Mets (47-53) snapped a two-game losing streak while the Yankees (53-48) saw their winning streak cut short at three games.

The Yankees mustered just two hits against Verlander, who continued to look like his old self, now with a 1.46 ERA over his last six starts. Alonso continued to show signs of turning a corner himself, recording his first two home runs since July 6 while going 3-for-4 with a walk and five RBIs.

Alonso was just part of the Mets’ onslaught against Domingo German, who was roughed up for a second straight start, giving up six runs across six innings.

The Yankees’ offense, coming off scoring 18 runs in a three-game sweep of the lowly Royals over the weekend, was unable to build on that momentum. The Mets’ bullpen tried to offer them a lifeline across the final three innings, but it proved too little, too late on a night when the Yankees went 0-for-5 with runners in scoring position and left 11 men on base.

The Mets jumped out to a 1-0 lead in the first inning, which Brandon Nimmo led off with a double off the right-field wall. Two outs later with Nimmo on third, Alonso hit a well-placed bloop to left-center field that found grass among three Yankees for a 1-0 Mets lead.

Alonso’s single had an expected batting average of .050, but counted all the same.

The Mets ran a similar left-field bloop play in the third inning and found even more success with it. With two outs, Francisco Lindor skied a pop-up down the left-field line that Billy McKinney made a charge for but could not come up with, resulting in a double — despite having a .030 expected batting average.

After walking Jeff McNeil, German got ahead 0-2 on Alonso, before leaving a changeup over the plate. Alonso did not miss, cruising a three-run home run to center field to make it 4-0.

In the sixth inning, Alonso and Daniel Vogelbach led off with back-to-back home runs off German that extended the lead to 6-0.

With the Yankees down 7-0 in the bottom of the seventh inning, Anthony Volpe got them on the board with an RBI double off Brooks Raley. They went on to load the bases with one out, but only got a Giancarlo Stanton sacrifice fly out of it.

The Yankees reloaded the bases with one out in the eighth inning against Grant Hartwig, at which point Buck Showalter brought in David Robertson. The veteran put out the flames with the Yankees again only scratching across one run on a fielder’s choice by pinch-hitter Ben Rortvedt.

The Mets then added some insurance in the ninth as McNeil roped a two-run double off the struggling Ron Marinaccio.

But they got a late scare when Albert Abreu, called on to clean up Marinaccio’s mess, hit Mark Vientos and Francisco Alvarez on the hands with 98 and 97 mph sinkers, respectively. Vientos remained in the game while Alvarez, who actually struck out on the pitch he was hit by, was replaced by Omar Narvaez in the bottom of the ninth.
