The Mets made themselves right at home at Yankee Stadium on Friday.
They won both ends of a doubleheader against the Yankees and look to be on their way to getting a deep-pocketed owner.
And they ended the night by walking off the Yankees in their own stadium, as Amed Rosario finished the nightcap with a pinch-hit, two-run homer off Aroldis Chapman in the bottom of the seventh, with the Mets serving as the home team in a makeup game from last week’s postponement at Citi Field.
As Rosario circled the bases in the 4-3 win in the second game, he didn’t even realize the game was over until he saw his teammates pouring out of the visiting dugout to celebrate at home plate.
The dramatic victory came after a stunning comeback in the first game, when the Mets shook off a four-run deficit and scored five runs in the top of the sixth on their way to a 6-4 win.
And in that one, Dom Smith hit the go-ahead homer after Pete Alonso crushed a game-tying three-run shot — one of three home runs allowed by reliever Chad Green.
“This is the fight we’ve been having all year,’’ Smith said after the second game. “We haven’t come out on the right side when we’ve been behind. To come from behind in two victories hopefully sparks something.”
Smith would know.
It was his words and tears that impacted the entire sport on Wednesday and led to the movement not to play Thursday, as the sport looked to fight racial injustice.
On Friday in The Bronx, there was no talk of further postponements.
Instead, the Mets and Yankees took the field on Jackie Robinson Day and the Mets took another step in reviving their season.
The same cannot be said of the Yankees, who have lost seven straight — their longest such streak since 2017.
“It’s definitely a tough stretch,’’ Adam Ottavino said. “As tough as I can remember.”
And as the Mets congratulated Rosario, Clint Frazier said he took it all in.
“I sat there and watched the entire celebration,’’ Frazier said. “It’s not fun. Luckily, we have one [Saturday] and two [Sunday]. Hopefully we can get back on track because we need it right now.”
With injuries up and down their lineup, the Yankees have had to resort to some unfamiliar names.
But even their healthy players are unproductive, with Gary Sanchez searching for his timing and the Yankees failing to come through with runners in scoring position.
In the second game, the Yankees scored three runs off David Peterson in the top of the third, sparked by a leadoff walk from Jordy Mercer. Erik Kratz and Aaron Hicks delivered RBI singles and Sanchez drew a bases-loaded walk. But Mike Tauchman grounded into an inning-ending double play.
The Yankees loaded the bases again in the fifth, but the lost Miguel Andujar grounded out.
The Mets cut their deficit to a run with a Brandon Nimmo RBI double off Nick Nelson in the fifth.
And Chapman blew it in the seventh, much like Green did in the opener.
Chapman hadn’t pitched in 11 days, a situation Aaron Boone called “not ideal.”
He walked Jeff McNeil to open the bottom of the seventh and then caught pinch-runner Billy Hamilton off first, but Hamilton still stole second.
Rosario then turned on a hanging slider and sent it into the left-field seats, setting off a strange ending to a long day at Yankee Stadium.
Boone said he’s hopeful his team can turn it around soon.
“It’s what these guys do,’’ the manager said. “We’ve just got to start finishing off some games.”
