The secret to the Mets having a successful year is simple: Play the Marlins as often as possible.

The Mets snapped a three-game losing streak Friday with a 9-3 win over Miami in their home opener on a chilly day at Citi Field. They’ve now won four of five games against the Marlins this season — sandwiched around being swept in a three-game set in Milwaukee.

“The Brewers outplayed us, but we’ve got to turn the page,’’ Francisco Lindor said. “It’s part of being a good baseball team. Today was a good day for the New York Mets.”

Tylor Megill, filling in for the injured Justin Verlander, was excellent, tosssing six scoreless innings. The Mets hardly missed Verlander, who hopes to be back from the strained muscle near his right armpit by the end of the month.

The Mets’ hitters, who had been quiet for much of the early part of the season, erupted for a season-high nine runs.

Dennis Santana gave up a three-run home run to former Yankee Garrett Cooper with two outs in the eighth to make things interesting, but Lindor and Pete Alonso homered in the bottom of the eighth to end any drama.

The victory came in front of a packed house of 43,590, as the Mets debuted their giant new scoreboard above center field, as well as the much-derided corporate-sponsored patch on their jersey sleeve, which owner Steve Cohen said would be changed from its “Phillies colors” of red and white.

The owner also made it clear in a pregame meeting with the media that he was not overly concerned by the Mets’ sluggish start to the season, saying it was too early for any red flags.

Still, a win in front of the guy in charge doesn’t hurt.

“It took us a bit to break through, but when we did, we really did well,’’ said Brandon Nimmo, who walked a career-high four times. “It was good to put up some runs. We’ve got a lot of veterans and we understand one series doesn’t dictate a season.”

Nimmo led off the bottom of the first with one of the 12 Mets’ walks on the day. Though Nimmo was stranded on second after a steal, he helped set the tone for the afternoon.

Miami right-hander Edward Cabrera walked Jeff McNeil and Mark Canha to start the second inning, although the Mets failed to score again.

Megill pitched around a one-out double by Luis Arraez in the third before the Mets broke through in the bottom of the inning.

Cabrera, still unable to find his command, walked Nimmo, Starling Marte and Lindor to load the bases with no one out. Alonso and McNeil struck out looking before Canha managed to draw a walk to force in Nimmo for the first run of the game, ending Cabrera’s outing. Cabrera walked seven in just 2 ²/₃ innings.

Daniel Vogelbach then grounded to second, but Cooper, who was playing first base, also made a play on the ball and new pitcher Huascar Brazoban didn’t cover first. The play went for an infield single — the Mets’ first hit — and made it 2-0.

Megill survived a scare in the top of the fourth, when he took a 107 mph line drive off his right foot for a single by Jean Segura. Megill was knocked to the ground and remained down briefly, but remained in the game.

The Mets added another run in the fourth, when Alonso delivered a two-out RBI single to score Tomas Nido. Starling Marte hit his first home run of the season in the sixth, a solo shot that gave the Mets a 4-0 lead.

Megill allowed just three hits and a pair of walks in his 88-pitch outing, a second straight strong start against Miami.

Adam Ottavino tossed a perfect seventh before Santana retired the first two batters he faced in the eighth. He then walked two straight before Cooper homered to make it a three-run game.

Brooks Raley got out of the inning, and Lindor hit a two-run home run in the bottom of the frame — his first homer of the season —before Alonso also went deep.
