Neil Walker knew if Ronald Torreyes’ spot in the order came up in the ninth and there was a right-hander on the mound, Aaron Boone would call his name.

He knew one more thing, as well: “You try to step in the box and assume the first pitch you see is gonna be the best pitch you see. You try to be aggressive, but more than that, you try to be on time.”

Walker was all of that, as he launched the first pitch he saw with one out in the bottom of the ninth into the right-field seats. The pinch-hit homer off Dylan Covey gave the Yankees a 5-4 win Tuesday night and capped a rally from four runs down, as Miguel Andujar and Aaron Hicks each hit two-run blasts on a steamy night in The Bronx.

“Everyone would tell you that you want to score early and not make it like that,” Lance Lynn said of the comeback. “But it was a fun ending, wasn’t it?”

With the Red Sox snapping a three-game losing streak by beating the Rays, the Yankees remained 6½ games back in the AL East, but they avoided a second straight loss to Chicago, and another listless showing after Boone called the team “sluggish” following Monday’s loss.

After the Yankees fell behind 4-0 following Chicago’s three-run sixth in which Lynn and Jonathan Holder combined to give up four consecutive singles, it seemed Boone might have some other words for the Yankees, but their bats finally awoke in the bottom of the inning.

James Shields allowed just one hit until Brett Gardner started the bottom of the sixth with a triple, but the struggling Giancarlo Stanton popped out, as did Hicks. Andujar followed with his two-run shot to left. His 22nd homer of the year got the Yankees to within 4-2.
Luke Voit then singled to center and Gleyber Torres walked on four pitches.

That set up Greg Bird against lefty Jace Fry. Bird, booed throughout the game, lined a shot to right-center, but Avisail Garcia tracked it down.

The comeback continued in the bottom of the eighth, as Stanton snapped an 0-for-14 streak with a single to start the inning and Hicks tied it with a shot to right, his 22nd, as well.

“That rejuvenates the entire team,” Walker said of Hicks’ homer.

And when Dellin Betances shut the White Sox down in the ninth, the Yankees had their chance.

Austin Romine struck out to open the bottom of the inning, but Walker delivered.

“He’s had a lot of big hits for us,’’ Boone said. “I felt so bad [because] we needed to get him a day [off] and he goes up there with one pitch and ends it. He’s been really valuable for us.”

That’s been the case for a while now, since Walker has gotten regular at-bats and shaken off a dreary start to the season.

Originally signed late in spring training as insurance in case Torres wasn’t ready to play, Walker has ended up at first, second, third and even right.

“I certainly didn’t think I’d find myself in the outfield, but it’s about finding ways to win every single night,’’ Walker said. “All I was looking for when I came here was an opportunity, and you know over the course of a season you go through a lot of guys. I was playing right field [Monday] and I was looking around and the only other guy [who was playing where they were] on Opening Day was Hicks.”

The Yankees have survived the chaos that has resulted from so many injuries to key players and are now 9-1 when Lynn and other new arrival J.A. Happ have started for them.

“I was looking for an opportunity,’’ Walker said of his mindset before he joined the Yankees. “I wanted to be part of a winner and contribute any way I could.”

Even he couldn’t have predicted how that has unfolded, but Tuesday was another highlight.
