NEW YORK

Henry Owens took a moment to enjoy the setting — major league debut, Yankee Stadium, sellout crowd for a matchup between longtime rivals.

Then he went to work, quickly settled into a rhythm and definitely looked like he belonged in the bigs.

The rest of the Red Sox pitchers who followed the rookie, well, they seemed totally overmatched.

Brian McCann and Chris Young hit three-run homers during a nine-run burst in the seventh inning and the New York Yankees broke loose once again, romping past Boston 13-3 Tuesday night.

“Once he came out of the game, they had their way with our bullpen,” Red Sox manager John Farrell said. “Tried to find guys that at least stem the tide, shutdown an out when needed, but the way they’re swinging the bat, the runs that they’re scoring of late, it was not a good matchup against our bullpen tonight.”

Down 2-1 and held to three singles by Owens going into the sixth, the Yankees suddenly struck. The AL East leaders wound up scoring in double figures for the fourth time in seven games — they’d gone more than a month without doing it until a 21-5 rout at Texas last week.

Overall, the Yankees have totaled 90 runs in 10 games. They did most of their damage this time against relievers Robbie Ross, Jean Machi, Craig Breslow and Alexi Ogando.

“Every guy we brought to the mound, some pitches found the middle of the plate,” Farrell said. “They didn’t miss them.”

Promoted from Triple-A Pawtucket, the highly touted Owens by far was the best Boston pitcher of the night.

“I was anxious to be out here and excited, pleased with the opportunity and tried to seize it the best I could,” the 23-year-old lefty said.

“I looked around when I was warming up. Kind of ‘here I am,”’ he said. “So I tried to embrace the best I could and try to have fun at the same time.”

Owens (0-1) began his big league career by striking out Jacoby Ellsbury with a sweeping breaking ball. He had a little trouble with command later in the first inning, and a single by Young, a walk and single by Mark Teixeira produced a run.

But after Chase Headley hit a leadoff single in the second, Owens retired 12 straight batters.

Owens helped himself by working fast.

“I was giving them time to get in the box, and I did not want to make any friends today,” he said.

Owens exited after Young opened the sixth with a single and Alex Rodriguez doubled to the wall. Owens gave up five hits, struck out five and walked one.

“If he gets Rodriguez out, he’s staying in the ballgame,” Farrell said. “But they’re into the third time in the order, didn’t want to over expose him. He’s approaching 100 pitches in that sixth inning. But for the time he was on the mound, I thought he handled the situation well.”

Last-place Boston lost its eighth straight on the road.

Masahiro Tanaka (8-4) left after Pablo Sandoval’s long home run leading off the seventh got the Red Sox within 4-3.

The Yankees’ big seventh began when shortstop Xander Bogaerts bounced a throw for an error on Ellsbury’s leadoff grounder.

McCann hit his 18th homer and drove in four runs.
