NEW YORK -- As Aroldis Chapman ran toward the mound for his anticipated debut, a flame-filled graphic surrounded his name on the Yankee Stadium scoreboard.

Then the new Yankees closer lived up to the graphic by reaching 101 mph several times during the ninth inning.

Chapman allowed a run in the ninth but quietly completed New York's 6-3 victory over the Kansas City Royals Monday night.

The left-hander returned from his 30-game suspension for an offseason domestic-violence incident and was activated from the restricted list. He was told by manager Joe Girardi he would pitch Monday and began warming up during the bottom of the eighth after Andrew Miller and Dellin Betances had briefly warmed up in case the score was closer.

After the Yankees finished batting in the eighth, Chapman ran to the mound to cheers from the crowd of 41,243 while the graphic highlighted his ability to throw fastballs 100 mph.

"I was very excited and happy to see the fans receive me the way they did," Chapman said through an interpreter. "After the reaction I got today, I can say it was incredible."

Chapman entered in a non-save situation as the Yankees held a 6-2 lead.

His first two pitches to Omar Infante were strikes clocked at 100 mph. His next two were out of the strike zone and clocked at 101 mph.

"Chapman is a great guy to have," said designated hitter Carlos Beltran, who hit two of New York's five solo home runs off Chris Young. "I think right now in the bullpen, having Miller, Betances and him now, I think they give us three guys that we can use, seven, eight and nine. They're power guys."

Chapman reached a full count when he threw an 88-mph pitch over catcher Brian McCann's glove but struck out Infante swinging on a 97 mph fastball. He struck out Cheslor Cuthbert on a 101-mph fastball, then gave up a double to pinch hitter Paulo Orlando and an RBI single to Alcides Escobar.

"I was trying to hit a ball and that's it," Escobar said. "Not trying to do too much with this guy... A fastball like that, 100 miles per hour, you can't do too much. You just try to put the ball in play and that's it."

After Escobar's single, Chapman finished his 17-pitch outing by fielding Lorenzo Cain's soft grounder and accepting handshakes from his teammates, who along with the crowd had been reacting to the velocity.

"You could just feel the electricity," Betances said. "When he's warming up, you see everybody in the bleachers just get up and take their phones out. It's a show. It's impressive. It's fun to watch for sure."

Before Chapman's debut, the Yankees hit five solo shots off Young (1-5). It was New York's first game with five home runs since Sept. 2, 2015.

McCann opened the scoring with his fourth home run with two outs in the first. The Royals tied it on Alex Gordon's fourth home run with nobody out in the second, but the Yankees never trailed after Beltran's first home run.

New York then added three more home runs in the third. Brett Gardner and Aaron Hicks began the inning with home runs and Beltran recorded his 38th career multi-homer game with a two-out drive to right field.

Hicks drove in New York's final run with a sacrifice fly in the seventh.

Yankees right-hander Ivan Nova made the start in place of injured left-hander CC Sabathia and allowed one run and six hits in 4 2/3 innings. Official scoring rules did not allow him to qualify for the win since he did not last five innings.

Four relievers followed Nova, and Kirby Yates (2-0) was awarded the win after throwing 1 2/3 scoreless innings.

Young lasted 2 1/3 innings and gave up five runs and six hits. He has allowed 13 home runs this season, and he matched the team record held by Sean O'Sullivan for home runs allowed in a game.

"It's a horrible feeling, feeling like you're letting a team down and not even giving them a chance," Young said. "It's certainly not what I expect from myself."

Eric Hosmer homered in the eighth for the Royals, who lost for the 10th time in 12 road games and 10th time in the last 13 games overall.

NOTES: The Royals were in New York for the first time since the World Series and stayed in the same Manhattan hotel. "The memories would be a little bit better if we were playing better," Kansas City manager Ned Yost said. ... New York was without CF Jacoby Ellsbury (hip) and 2B Starlin Castro (rib/oblique). Ellsbury jogged on a treadmill but manager Joe Girardi said he is unlikely to play Tuesday while Castro said he could have started Monday. ... To get LHP Aroldis Chapman on the 25-man and 40-man rosters, the Yankees optioned RHP Johnny Barbato to Triple-A Scranton/Wilkes-Barre and transferred Branden Pinder (elbow) to the 60-day disabled list. ... According to MLB.com's Statcast, 3B Eric Hosmer's 447-foot home run Sunday in Cleveland was the longest of his career in the regular season and the longest by a Kansas City hitter this season.
