KANSAS CITY, Mo. — The Yankees took their heavy-hitting lineup on the road and showed on Friday night they can still produce away from The Bronx. 

They blasted four more homers in a 12-2 rain-shortened eight-inning victory over the Royals at Kauffman Stadium to win their seventh straight and ninth in their last 10 games. 

And they’ve scored double-digit runs for the fourth time in five games. 

Anthony Rizzo and Giancarlo Stanton got the offense going with a pair of homers in the first and Aaron Judge helped seal the victory with a three-run blast in the seventh. 

The home runs gave the Yankees 18 in their last seven games, a stark turnaround for an offense that homered just twice in their seven games prior to this stretch. 

Prior to the game, Aaron Boone was optimistic that the success of the recent undefeated homestand would continue on the road. 

“Hopefully, it translates everywhere,’’ Boone said of his team’s power surge. “When we’re at our best, we hit well at our place. We know how to use that to our advantage. A lot of guys are getting settled into their seasons and swinging a little better.” 

It made a winner of Nestor Cortes, who had perhaps his most uneven outing of his excellent start to the season, but still managed to allow just one earned run in five innings. 

The Yankees took a quick 3-0 lead in the top of the first against left-hander Kris Bubic. 

DJ LeMahieu led off with a double to right to continue his hot hitting. After Judge was robbed of a run-scoring single by a diving Michael A. Taylor in center, Rizzo delivered a two-run homer, his MLB-high ninth of the season. 

Stanton followed with his fourth home run of the year to make it 3-0. 

Kansas City answered back with a run in the bottom of the inning, getting a double to left-center from Whit Merrifield, which glanced off the glove of left fielder Tim Locastro. 

Merrifield moved to third on an Andrew Benintendi grounder and scored when perennial All-Star catcher Salvador Perez snapped an 0-for-16 skid with a double to left. Perez entered the game 2-for-4 against Cortes — and both hits were homers. 

The Yankees caught a break in the bottom of the second. 

Bobby Witt Jr. doubled with one out and with Edward Olivares at the plate, wandered too far off second and Cortes fired to Gleyber Torres to start a rundown toward third, but Torres never threw to LeMahieu covering the base. 

Witt slid in ahead of the closing Torres, but Torres charged into Witt and Witt slid off the bag and was ruled out by third base umpire Manny Gonzalez, who ruled that the rookie slid over the bag himself. 

Kansas City manager Mike Matheny argued the call with Gonzalez and was tossed. 

Olivares followed with a single, moved to second on a passed ball by Kyle Higashioka and scored on a single by Taylor to cut the Yankees’ lead to 3-2. 

Following Stanton’s homer, Bubic settled in and retired 10 straight and 14 of the final 15 batters he faced. 

Cortes left after five innings, having mostly pitched around a season-high seven hits. 

Jonathan Loaisiga pitched a perfect sixth before the Yankees put the game away in the seventh. 

Isiah Kiner-Falefa’s one-out single to shallow right started the rally before Higashioka drew a two-out walk. LeMahieu then hit a liner to Nicky Lopez at short, but Lopez couldn’t handle it and it landed in left field, which allowed Kiner-Falefa to score and the inning to continue. 

Judge made the Royals pay with a three-run blast to right- giving him three homers in four games and five in his last seven. And Gleyber Torres added his second of the season in the eighth. 

The Yankees weren’t done, as Higashioka belted a three-run double later in the inning.
