The daily questions surrounding the Marlins’ lineup no longer include who plays what position or where they are hitting in the lineup. Instead, it’s shifted to “Who?”

The team is currently playing without more than half of its Opening Day roster following its coronavirus outbreak that has infected 21 members, at least 18 of whom were players. Somehow, that has the Marlins playing some of their best baseball in years.

In the Marlins’ first action since their season went on pause, they completed a four-game sweep of the Orioles on Thursday — their first four-game sweep since April 2016 against the Dodgers.

After their 4-3 win over the Mets on Friday night at Citi Field — making it six in a row — the Marlins sit atop the National League East with a 7-1 record.

Still, for Marlins manager Don Mattingly, they’re only as good as their last result.

“Obviously, the feeling is good because you’re winning, and that’s always good,” Mattingly said before the game. “But when you go to the next city, you got to establish yourself again. It starts with [Friday].”

The rag-tag group that started their three-game series against the Mets included 10 players from Jupiter, Fla., where the team’s top prospects have been stationed without the minor leagues this year, and various players picked up in free agency or through trades. The 13 Opening Day Marlins who did not test positive — who have dubbed themselves “The Trece” (13 in Spanish) — round out the rest of the active roster.

One addition — 30-year-old Eddy Alvarez, who made his MLB debut Wednesday — is a former Olympic speed-skater. The team has been a beacon of hope for players either trying to start or prolong their careers, with new members coming and going every day.

The team didn’t even name its Friday starter, Humberto Mejia, until hours before the game.

“People are coming up or coming in and they’re having success,” said Mike Morin, who made his Marlins debut and pitched two scoreless innings in the team’s 8-7 win over the Orioles on Thursday. “And your confidence continues to grow and grow. People have a lot of energy, and it’s fun to be around.”

The Mets, however, aren’t exactly sharing the ever-glowing glee in Miami’s clubhouse. It was the Marlins, after all, that forced the league to tighten its restrictions for traveling teams.

“I think anyone would be a little ticked off, but hopefully everyone now in the Marlins and Cardinals organization is doing well, but we just got to try and do a better job of social distancing and keeping the mask on and keeping away from each other, and if we do that, we’ll be fine and be able to finish the season,” said Robert Gsellman, who was reinstated off the injured list before the game.
