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.

Even though this Mets team is undeniably different from its recent predecessors, with more realistic postseason aspirations, the fog of past seasons can be difficult to disperse. So when the Yankees strutted into Citi Field on Tuesday and immediately hammered consecutive homers over the fence, the Bronx portion of a sold-out crowd made its confidence known.

It was loud and it was antagonistic, until the Mets did something they’ve done so infrequently over the decades-long run of this rivalry: They punched back.

Four of the first six Mets batters clubbed extra-base hits in the bottom of the first inning, including a solo homer from Starling Marte and a go-ahead two-run shot by Eduardo Escobar. The resulting lead held through the middle innings and onto the end game, when Edwin Díaz nailed down the final four outs of a 6-3 win over the Yankees.

“I’ve never played in a Major League playoff game before,” first baseman Pete Alonso said, “but if I had to guess, that’s what it would be like.”

Saquon Barkley likes being a New York Giant. 

Three years after former general manager Dave Gettleman delivered an infamous line about Odell Beckham Jr.’s trade market that turned out to be misleading, the Giants are back at the NFL Scouting Combine with another injury-plagued star caught up in trade rumors. 

That, however, is where the comparison ends. 

Barkley’s strong preference is to stay with the Giants even as they start another rebuilding process, according to a source. A handful of agents, coaches, scouts and executives surveyed in Indianapolis agreed the Giants would need to be blown away to trade away Barkley, who is still the face of the franchise. 

General manager Joe Schoen, who replaced Gettleman in January, said the Giants are “open to everything” in response to a question that singled out Barkley. That answer was misconstrued in some corners of the viral news vortex to make it sound as if Barkley was being shopped, which is not the case.
