MIAMI — Meet the new bullpen, same as the old bullpen.

A day after the Yankees remade their bullpen by acquiring three relievers at the trade deadline, all three helped set fire to a game the Yankees should have won easily.

Jake Bird and David Bednar combined to give up six runs in the seventh inning to erase a five-run lead before Camilo Doval — with an assist from new utilityman José Caballero, who committed a costly error in right field — coughed up a two-run lead in the bottom of the ninth.

The end result was a devastating, wild and stunning 13-12 loss to the Marlins on Friday night at loanDepot Park.

Former Yankees prospect Agustin Ramirez, the headliner in the Jazz Chisholm Jr. trade at last year’s trade deadline, delivered the walk-off hit, a dribbler in front of the plate that went just far enough to score Xaiver Edwards from third base.

Doval had recorded the first out before giving up a single and a walk to the Nos. 8 and 9 hitters. Edwards then hit a single to right field that went under the glove of Caballeros, allowing both runners to score to tie the game at 12.

Ryan McMahon had put the Yankees up 11-10 in the top of the ninth with an RBI single that scored Caballeros, who had entered as a pinch-runner. Anthony Volpe then capped off his four-hit night with a double to center that made it 12-10.

Volpe had tied the game 10-10 in the eighth with his seventh home run in his last 13 games.

Bird and Bednar, who took a redeye together from Denver late Thursday night and landed here in the early morning, combined to lose the Yankees’ five-run lead in the seventh inning. They gave up six runs before they could get three outs, allowing the Marlins to somehow take a 10-9 lead.

Bird entered to start the seventh for what looked like a soft landing spot. But he gave up a pair of singles around a strikeout and then walked a batter to load the bases for Kyle Stowers, who clobbered a grand slam that pulled the Marlins within 9-8.

Aaron Boone then went to the bullpen for Bednar, who quickly got the second out before leaving a fastball down the middle to Javier Sanoja, who ripped it for a solo shot that tied the game at nine in stunning fashion.

Bednar followed by giving up a double to Jakob Marsee in his MLB debut, a single on a chopper over the mound and then a single from Ramirez that put the Marlins ahead 10-9.

After Volpe tied it in the top of the eighth, Bednar came back out for the bottom of the inning and struck out a pair in a scoreless frame.

Carlos Rodón carried a no-hitter into the fifth inning – though he had already walked three batters by that point – but then fell apart as his lack of command finally caught up with him. He could not make it out of the frame, giving up a two-run homer and then walking a pair to leave with two on and two out in a 6-2 game after throwing 107 pitches. 

Jonathan Loáisiga entered and hit a batter on his second pitch to load the bases for pinch-hitter Liam Hicks, who blooped a two-run single into left-center field to pull the Marlins within 6-4.

But Loáisiga got bailed out by third baseman Ryan McMahon, who made a slick pick on a hard ground ball from Kyle Stowers to collect the final out and strand a pair.

Rodón ended up being charged for four runs on a night when he walked five batters for the second time in his last three starts. The left-hander only gave up two hits and punched out nine, but too many walks marred what could have been a strong night.

Trent Grisham gave the Yankees some temporary breathing room in the top of the seventh, setting a new career-high with his 19th home run of the year, a three-run shot that clanked high off the right-field foul pole to put the Yankees up 9-4.

Making a return to his old stomping grounds, Giancarlo Stanton gave the Yankees an early jolt in signature fashion by smoking a three-run homer in the third inning for a 3-0 lead off righty Janson Junk. It came off his bat at 116 mph as the former Marlins slugger clubbed his ninth home run of the season, all coming in his last 21 games.

The Yankees then doubled their lead in the fifth inning against Junk, the former Yankees prospect who was traded to the Angels for Andrew Heaney at the 2022 trade deadline. Jasson Domínguez roped an RBI single that scored Volpe before Cody Bellinger followed with a two-run single that made it 6-0.
