MIAMI — Just three days ago, the Miami Marlins were reeling. They were in the midst of a franchise-worst losing streak. Their playoff hopes were fading with each passing game, each passing defeat.

“What 72 hours can do,” Marlins manager Clayton McCullough said.

For the Marlins, it just might have brought them back to life.

Miami on Wednesday erased a six-run deficit for an 8-6 win over the Philadelphia Phillies to sweep the three-game series at loanDepot park. Griffin Conine put the Marlins (55-54) ahead for good with a pinch-hit, two-run home run in the eighth.

According to the Elias Sports Bureau, the win marks the seventh time in franchise history the Marlins have erased a deficit of at least six runs to win against a divisional opponent and the first time since Aug. 23, 2019 against Philadelphia (seven-run deficit).

This came after Miami rallied from down three for an 8-7 walk-off win on Monday and gutted out a 1-0 victory on Tuesday behind a strong performance from ace Sandy Alcantara to win the series.

But to get the sweep?

“It’s vintage Marlins,” Conine said. “It’s what we’re all about — fighting up and down the lineup.”

The sweep was pivotal for Miami’s psyche as the team entered the set on a franchise-record 12-game losing streak.

It was also integral for them to keep their hopes of a playoff push alive.

Despite that franchise-record slide, Miami entered Wednesday two games back of the National League’s third and final wild-card spot but in a cluster with six other teams who entered the day within three and a half games of the second wild-card spot, currently occupied by the Phillies (57-52).

With one-third of the season left to play, the Marlins are still well within reach of a postseason berth.

“I hope we can now stop talking about what was and just get our sights moving forward,” McCullough said. “We all believed the whole time we were a much better team than how those couple of weeks had gone, but we need to play well to do that.”

The series overall against the Phillies was validation of that.

Wednesday was the latest example of their resilience.

The Marlins scored three runs apiece in the fifth and seventh innings to offset a rough start from right-handed pitcher Ryan Gusto, who gave up six runs on nine hits and two walks across five innings. Dax Fulton (two innings) and Tyler Zuber (one inning) threw three innings of scoreless relief while Miami’s offense rallied before Pete Fairbanks logged his 15th save of the season to secure the win.

After being shut out and held to one hit for four innings against Phillies starter Jesus Luzardo, shortstop Otto Lopez opened scoring for Miami in the fifth on an RBI groundout that scored Esteury Ruiz, who had doubled and advanced to third on a Jakob Marsse sacrifice bunt. Heriberto Hernandez then launched a two-run home run, his team-leading 16th of the season, to left-center field to cut Miami’s deficit to 6-3.

Miami’s three-run seventh started with a Ruiz single before he stole second and advanced to third on a throwing error. Marsee then walked with one out to put runners on the corners. A Lopez RBI single scored Ruiz before Xavier Edwards hit a two-run single to tie the game at 6-6.

And then Conine, who had the walk-off hit for the Marlins on Monday, obliterated a middle-middle change-up from Phillies reliever Jonathan Bowlan for a 424-foot home run.

“Definitely a pretty good stretch of for me personally and for the team,” Conine said. “I think we needed this series. I mean, winning the series [Tuesday] was big, but a sweep definitely feels like an exclamation point. After that 12-game stretch, this is a good way to come out of it.”

The Marlins now need to maintain that momentum they just re-acquired. They head on the road next for a four-game set against the New York Mets starting Thursday before playing at the Atlanta Braves for three games on starting Tuesday.

MLB’s trade deadline, set for 6 p.m. Monday is sandwiched between those series.

“Now you’re getting close to just 50 games left in this season,” McCullough said. “Whoever’s up next, they’re all going to be important games. ... We have to come out and just continue to play well.”
