The Phillies will open their wild-card playoff series against the Marlins at 8:08 p.m. Tuesday

NEW YORK — Do the Phillies have a first-round playoff opponent?

Go Fish.

The Phillies will face a familiar foe — the rival Miami Marlins — in the best-of-three wild-card round, a matchup that became increasingly likely over the last few days but wasn’t sealed until after Sunday’s regular-season finales. The series will begin Tuesday, with all games being played at Citizens Bank Park and will start at 8:08 p.m. on ESPN.

“Nothing’s going to be easy,” Kyle Schwarber said after the Phillies thumped the Mets, 9-1, to secure their first 90-win season since they won 102 games in 2011. “Miami’s a good team. We’ve got to do what we do.”

Although the Marlins and Arizona Diamondbacks clinched wild-card spots Saturday, they entered the last day of the season tied with 84 wins and jockeying for seeding. Both teams lost — Miami, 3-1, at Pittsburgh; Arizona, 8-1, at home against Houston — but the Marlins could point their plane toward Philadelphia by virtue of a tiebreaker.

The Phillies will be heavily favored, but it’s doubtful they will take the Marlins lightly. They lost the season series, 7-6, despite outscoring the Marlins by a 64-55 margin. The Marlins took two of three games in Philadelphia on April 10-12 and Sept. 8-10.

“They’re a good club,” manager Rob Thomson said. “They match up well with us. They can beat you in a lot of different ways. They’ve got pitching. We’ve got a lot of prep to do.”

But Miami’s roster is decidedly weaker than even a month ago.

Neither ace Sandy Alcantara nor 20-year-old phenom Eury Pérez will pitch in the playoffs because of injuries. Second baseman Luis Arraez, the National League batting champ, hasn’t started since Sept. 23 because of a sprained left ankle that worsened when he slipped on the dugout steps when the lights at Marlins Park were dimmed during a pitching change.

Through it all, the Marlins won five of their last seven games — and 10 out of 16 — to overtake the swooning Cubs in a four-team wild-card pileup behind the Phillies. They clinched a playoff spot with a victory in the penultimate game of the season.

And as banged up as they are, they could still present a matchup challenge for the Phillies because of their collection of left-handed pitchers — two starters and four relievers.

Here, then, are a couple of questions heading into the series:

For Brandon Marsh, a matchup with the lefty-heavy Marlins likely means a seat on the bench for the first two games.

Marsh entered play Sunday batting .221/.315/.358 against lefties. He hasn’t started against a lefty since Aug. 30. It doesn’t bode well for him that the Marlins have Jesús Luzardo (3.63 ERA) and Braxton Garrett (3.66) lined up to start Games 1 and 2, respectively, and a lefty-loaded bullpen with Tanner Scott, Steven Okert, Andrew Nardi, and A.J. Puk.

“I think, in time, he’s going to be consistent against left-handed pitching,” Thomson said. “Lately, he hasn’t seen the ball very well against them.”

But Marsh did take Mets reliever Anthony Kay deep in the ninth inning Sunday, his first homer against a left-hander since April 23.

Too little, too late?

“It makes you think, for sure,” Thomson said. “I’ll get with the staff and see where we’re at with lineups and rosters [Monday].”

If not Marsh, who would play left field?

The Phillies called up righty-hitting utilityman Weston Wilson over the weekend and played him in left field for a few innings Sunday in New York. Wilson had a 31-homer, 32-steal season — and a 1.025 OPS against lefties — in triple A.

But Thomson hinted that he might opt for Cristian Pache’s defense in left field, even though the righty-swinging Pache was 4-for-35 with 15 strikeouts since coming back from the injured list in early September.

“If you end up playing Miami and you get those left-handed starters — those starters are pretty good, too — you want to eliminate giving up runs as much as you can,” Thomson said. “So, [Pache] becomes maybe a factor. I haven’t talked to the rest of the staff, but that’s something that I’m thinking about.”

Check back Tuesday.

Arraez didn’t play Sunday and has gotten only one at-bat in the last nine days. But he did take grounders over the weekend, and Marlins manager Skip Schumaker sounded a positive note.

“He looked a lot better,” Schumaker told reporters Saturday. “The ground-ball work and the range, and the double-play plant-and-throw, the first step to get to attack the play, he checked a lot of boxes.”

The Marlins improved their offense around Arraez with deadline trades for Jake Burger and Josh Bell, a notorious Phillies tormentor. Entering play Sunday, they were slugging .423 and averaging 4.3 runs per game since the beginning of August, compared to .399 and 4.1 runs per game before that.

In some ways, the Phillies’ season turned Aug. 2 in Miami.

They lost, 9-8 in 10 innings, after Trea Turner booted a routine ground ball. Turner punished himself with a late-night hitting session that went public, and when the teams returned home two nights later, the struggling star shortstop got standing ovations that sparked his two-month torrid streak.

But something else happened in that game. The Marlins scored twice against Craig Kimbrel and appeared to uncover a tell that enabled them to steal his signs when they got a runner to second base. Kimbrel even intentionally balked to move a runner to third.

Kimbrel appears to have fixed the problem. But the point is, there won’t be any secrets between the division rivals, which may level the playing field if the talent is skewed toward the Phillies.

“It doesn’t need to look pretty, it doesn’t need to look sexy,” Schwarber said. “We’ve just got to find a way to win a game at the end of the day.”

Two, actually. It starts Tuesday.
