Hours after the Knicks clinched their first title in more than half a century, the Mets were back at Citi Field in their latest attempt to salvage their season.

At times, the park seemed transformed into Madison Square Garden East, complete with plenty of Knicks organ melodies taken straight from the World’s Most Famous Arena.

And against the Braves on Sunday, the strategy seemed to work, as the Mets beat their first-place rivals 8-1.

“It’s huge,” Freddy Peralta said of the series win. “It reminded ourselves how good we are.’’

That remains debatable, as the Mets are still seven games under .500 (32-39) and a ways away from threatening for a playoff spot.

But they at least held their own against Atlanta, thanks to a bounce-back start from Peralta, a breakout game at the plate from A.J. Ewing and solid work out of the bullpen.

Now, the Mets will look to build on this little bit of success as they head out on the road, where they haven’t played well.

They’ll face the Reds — one of the seven teams they have to pass to get into the playoffs — in Cincinnati beginning Monday then visit the resurgent Phillies.

“I’ve been saying, for us to turn this thing around, we have to start winning series consistently,’’ Carlos Mendoza said. “It doesn’t matter the schedule [or] the teams, we have to control what we can control and start playing our best baseball here going forward without getting too far ahead. It was good to see the guys playing well against a very good team.”

The Mets used a four-run first inning and five solid innings from Peralta en route to the victory, as Peralta was much better than in his previous outing, when the right-hander allowed a season-worst six runs.

He allowed three straight singles to start the game, as Atlanta loaded the bases with no one out for Ozzie Albies, who whiffed for the first out.

Ex-Met Dominic Smith followed with a sacrifice fly to left that drove in Michael Harris II for the first run of the game.

Austin Riley popped out to second to end the 28-pitch inning after just one run scored.

The Mets knocked around right-hander Bryce Elder in the bottom of the inning to go ahead.

Carson Benge led off with a walk, and Bo Bichette singled to left. Juan Soto followed with a bizarre bunt attempt that turned into a force-out at third, as he left it just in front of the plate.

Jared Young helped make up for Soto’s mistake with a run-scoring single to center to tie the game. Ewing gave the Mets the lead with a double to left that scored Soto. It was the first of his three hits on the day.

On the double, Mike Yastrzemski’s throw from the left field corner hit the pole in front of the netting down the third base line. The error allowed Young to score and Ewing to move to third.

With two outs, Brett Baty singled to make it 4-1. Baty reached base four times.

Peralta, meanwhile, recovered to retire 14 straight after allowing those first three batters to reach.

Ewing’s strong day continued in the fifth, as he opened the bottom of the inning with a homer to right. Marcus Semien followed with a homer to center; Harris grabbed the ball as he leaped above the wall, but it bounced out to his apparent astonishment, making it 6-1.

A two-run single by Juan Soto sealed the win.

Cionel Pérez took over for Peralta to start the sixth and combined with Daniel Duarte, A.J. Minter and Huascar Brazobán to close out the game with four scoreless innings.

“We’re just trying to win games,’’ Ewing said. “No matter who we play.”
