The Yankees entered the ALDS with an unsettled bullpen and plenty of question marks about how they would navigate the late innings.

Five games and five appearances later, Wandy Peralta has them feeling a whole lot better and ALCS-bound.

The veteran left-hander finished off a 5-1 win over the Guardians in Game 5 on Tuesday night with another scoreless ninth inning, part of a strong effort from the Yankees bullpen to cover the final four innings of the clincher.

Peralta finished the series — which included him throwing on three straight days for Games 2-4 — with six innings of work, giving up just two runs on four hits while striking out seven.

“He has brass balls,” catcher Kyle Higashioka said. “The guy can handle any pressure situation you put him in. … He goes after hitters, trusts his stuff. You always see the best version of him.”

Peralta, who finished the regular season on the IL with thoracic spine tightness, became the first Yankees pitcher to appear in all five games of an ALDS. He recorded the save in Game 4 in Cleveland to send the series back to The Bronx, where he secured Game 5.

“He pitches with a lot of heart,” Clay Holmes said. “Throwing five out of five games here, he was up a lot. He’s just a guy that wants the ball. When you have a guy like that in the bullpen, it rubs off on each other, his attitude of wanting the ball. What he brings not only on the field, but off the field has been huge.”

Holmes also had arguably his best outing since returning from the shoulder strain he dealt with at the end of the regular season. He threw a perfect eighth inning against the heart of the Guardians’ lineup, striking out a pair.

While Holmes was in the middle of a Game 3 controversy after the Yankees blew a two-run, ninth-inning lead without him — manager Aaron Boone said he was not available, which Holmes contradicted — he came back with strong outings in Games 4 and 5.

“The sinker’s been feeling good,” he said. “I definitely think I have enough outings under my belt now where I’m starting to get in that routine physically and the shoulder’s starting to adapt to the intensity. I’m definitely in a good rhythm right now and things went pretty well this series.”

Before Peralta and Holmes, Jonathan Loaisiga delivered two scoreless innings on Tuesday as the first reliever out of the bullpen.

The Yankees were far from absolved of all their bullpen questions as they headed to Houston for the ALCS, but Peralta and Co. at least offered some reasons for encouragement.

“It’s so exciting to be in the game in situations like that,” Peralta said through an interpreter. “[The coaching staff has] given me the confidence to be in those games, and for me, we just have to keep doing our job. Work, keep doing our job and focus and expect to be in there in those games.”
