TORONTO — Most of the praise Austin Wells has received in his first month as a big-leaguer has come for his work behind the plate and learning a new pitching staff.

But it was his bat that was his calling card through his rise to the Yankees, and it has started to get louder over the past week.

Wells crushed a two-run home run off Blue Jays closer Jordan Romano in the ninth inning Tuesday night to lift the Yankees to a 2-0 win at Rogers Centre.

With his second home run in as many days — and third in his last five games — Wells helped the Yankees (80-77) keep the Blue Jays (87-70) from inching closer to a playoff spot, at least for a night.

“It’s unbelievable,” Wells said. “Coming in here and getting to have a hit like that in the late innings is what you play the game for. Felt good and glad I had the opportunity to be up there in that situation with the guys on the mound putting us in that situation.”

In addition to his clutch home run, Wells caught a shutout that was led by Michael King, who continued to look strong in his audition to make next year’s rotation.

Even without his sharpest stuff (five walks), King one-hit the Blue Jays across six shutout innings while facing them for the second time in a week.

He now has a 1.05 ERA in seven starts since ditching the bullpen.

Over his last eight games, meanwhile, Wells is 8-for-29 with three home runs and three doubles after a quiet start to his big-league career at the plate.

“He’s been swinging really well now finally this last week,” manager Aaron Boone said. “He’s started to get more and more comfortable. You’ve seen from the jump — hitterish in the box, he’s got that. Now he’s starting to get some results, really starting to drive the ball. That’s a good one the other way off Romano. He’s starting to string together a lot of good at-bats. … He’s looking good.”

In his first at-bat Tuesday, Wells flew out to the warning track in center field off Kevin Gausman, who tossed seven shutout innings. But against Romano in the ninth, he took a 96 mph fastball the other way for the go-ahead blast.

“That’s what I’m trying to do with a pitch middle-away — take it the other way,” Wells said. “I think that means that my bat’s flattening out a bit. That’s where I want to be and that’s what I’m trying to continue to do.”

Before Wells went deep, the Yankees’ best chance to score came in the seventh inning when they had runners on the corners with one out. But Giancarlo Stanton’s lack of speed continued to stick out like a sore thumb when he was thrown out trying to score from third on a chopper to shortstop Bo Bichette, who was playing a few steps closer than halfway on the dirt.

The Yankees had some strong defense of their own to maintain the shutout, including from Oswald Peraza at shortstop. In the fifth inning, Peraza cleanly backhanded a ground ball to the hole and unleashed a strong throw to nail Alejandro Kirk in plenty of time at first.

“He made that play like he was bored,” Boone said with a grin. “That’s a special play. That’s what he is defensively.”
