The true test may come in October, but for now, the Mets are kings of New York.

Starling Marte hit a walk-off single against Wandy Peralta in the ninth inning Wednesday, leading the Mets to a 3-2 victory and a two-game series sweep of the Yankees at Citi Field. The series marked the first time in history the Mets and Yankees both entered a regular-season Subway Series in sole possession of first place.

The winning rally began when Eduardo Escobar hit a leadoff double and moved to third on Tomás Nido’s sacrifice bunt. Following a Brandon Nimmo infield hit, Marte lined a single into left field to walk it off.

Max Scherzer gave the Mets seven scoreless innings on his 38th birthday, twice striking out Aaron Judge with two men on base (and joining Oakland’s Frankie Montas as the only pitchers to whiff Judge three times in a game this season). But after Scherzer departed, the Mets — with a short bullpen — turned to starting pitcher David Peterson, who allowed a game-tying homer to Gleyber Torres on his fifth pitch.

Seth Lugo entered from there and retired five of the six batters he faced, including Judge, who finished 0-for-5.

Longtime WWE chairman and CEO Vince McMahon officially announced his retirement in a post shared on his verified Twitter account.

“At 77, time for me to retire,” McMahon tweeted. “Thank you, WWE Universe. Then. Now. Forever. Together.” 

McMahon’s decision comes one month after his announcement to voluntarily step down from his responsibilities amid an ongoing investigation into alleged misconduct and would be replaced by his daughter, Stephanie, on an interim basis.

The announcement also comes after his son-in-law, Paul ‘Triple H’ Levesque announced he would will resume his executive position as WWE’s EVP of talent relations effective immediately.

Braxton Berrios, who signed with the Jets for two years at $12 million this offseason, is all in on the youthful revival of the team.

“We have a lot to do,” Berrios said. “We have all the tools to be able to do that, absolutely.”
