After losing yet another high-leverage reliever to the injured list before the Subway Series opener, Aaron Boone said the Yankees would “piece together” the ninth inning without a set closer. 

On Monday, that meant asking Jonathan Loaisiga to record the final four outs and the right-hander delivered. 

Loaisiga tossed a perfect 1 ¹/₃ innings to finish the game, recording his first save of the season in the Yankees’ 4-2 win over the Mets at the Stadium. 

A day after the Yankees closed out a win with 2 ¹/₃ innings from Lou Trivino — without Scott Effross (shoulder strain), who landed on the IL Monday — the Yankees got 1 ¹/₃ scoreless innings from Ron Marinaccio before turning it over to Loaisiga, who was sharp while facing the heart of the Mets’ order. 

“For him to come in and throw the ball like that, that’s what he’s capable of,” Boone said. “That’s what we’re working to get him to. Encouraging to see him go out in the biggest spot in this game and just really execute.” 

After getting Starling Marte to fly out as the potential tying run in the eighth inning, Loaisiga returned for the ninth and got Francisco Lindor to ground out and Pete Alonso to fly out. 

The Yankees had left-hander Wandy Peralta warmed up in the bullpen, and he could have been an option to face the left-handed Daniel Vogelbach with two outs. But Boone stuck with Loaisiga, who got Vogelbach looking at a changeup for strike three to end the game. 

“Definitely a lot of adrenaline,” said Loaisiga, who has had an up-and-down season after a dominant 2021. 

Loaisiga became the 11th different Yankee to record a save this season, the most of any team in the majors this season and the most in franchise history. It’s possible the Yankees will add to that tally as they wade forward without the services of injured relievers Effross, Clay Holmes (back spasms), Miguel Castro (shoulder strain), Zack Britton (UCL surgery) and Albert Abreu (elbow inflammation). 

The Yankees thought former closer Aroldis Chapman had turned a corner, after a solid nine-game stretch without giving up a run, but his command issues have returned in his last two outings, further clouding Boone’s options. 

While Clarke Schmidt was called up to take Effross’ spot in the bullpen, Boone was hopeful that Effross could return “in a few weeks” after an expected shutdown of a week to 10 days before ramping back up. 

“However we can get to the finish line, we’ll kind of piece it together the best we can while we get some guys back,” Boone said. “Hopefully it is something that will declare itself over the next several weeks where guys can start to grab onto some roles and we can get a little more defined as we unfold over the next few weeks.”
