New York — Yankees hitters have clawed out of an early-season slump with a string of clutch, late-game hits.

The Bronx Bombers needed no such fireworks in this one — a start-to-finish shellacking that’s inspiring confidence ahead of a weekend series in Boston.

“It’s good to see these guys starting to get a little bit of that swagger,” manager Aaron Boone said.

Aaron Judge homered for the first of his three hits, Gary Sánchez connected for the second straight game and New York got its first blowout victory in a month, beating the Kansas City Royals 8-1 Thursday.

Judge got the Yankees started with a solo shot in the first, Luke Voit had another in the third and Sánchez blew the game open with a three-run drive in the sixth.

New York had not won by more than four runs since a 7-0 rout of the Chicago White Sox on May 22.

The Yankees have won seven of nine, and seven of their eight wins before Wednesday had come via comebacks. Boone said it felt like a long time since New York’s last easy victory, adding that the morale boost — along with all the rested relievers — could benefit the Yankees at Fenway Park.

“We’ve obviously played a ton of close games this year, which I believe is going to serve us well moving forward,” Boone said. “But it is nice, definitely, to have these types of games.”

New York hasn’t played in front of fans in Boston since 2019. The Red Sox swept three games at Yankee Stadium in early June and entered Friday 4 1/2 games ahead of New York for the AL East lead.

“It’s going to be fun,” said Giancarlo Stanton, who had three hits. “We’re ready to go.”

Jameson Taillon (2-4) matched a season high by pitching 6 1/3 innings and ended an eight-start winless streak. The right-hander allowed a run, five hits and two walks while striking out six on 96 pitches.

“I thought his curveball was as good as I’ve seen it,” Boone said.

Nestor Cortes Jr. finished out the six-hitter with 2 2/3 scoreless innings. Brett Gardner made a sliding catch in center on Whit Merrifield’s popup for the final out.

Brad Keller (6-8) allowed four runs in five innings for Kansas City, which was trying to win a series against New York for the first time since 2015. Keller walked four and allowed nine hits, including the homers by Judge and Voit.
