On Monday night, even with the long-awaited and impactful season debut of Giancarlo Stanton, it was more of the same for the suddenly lifeless Yankees offense.

The club’s scoreless streak, dating to the start of Sunday’s loss at Boston, reached 20 innings by the end of a miserable 1-0, 11-inning loss to the Angels  in front of 37,398 at Yankee Stadium.

Not even the designated runner on second could help produce a run for the Yankees (42-29), who have lost four in a row. With the bases loaded and two outs in the 11th, Anthony Volpe grounded out to third baseman Luis Rengifo, who stepped on third to end it.

“When you’re not hitting the ball out of the ballpark and you’re having some hard time scoring runs, you got to take advantage of some situational things that come up,” Aaron Boone said. “And we had some leverage there late with a runner on second and just couldn’t push it around.”

Aaron Judge was intentionally walked with none out to begin the final frame before Cody Bellinger flied out to right, moving ghost runner Paul Goldschmidt to third.

Goldschmidt was thrown out at home on Jasson Dominguez’s broken-bat grounder to second baseman Christian Moore. Jazz Chisholm Jr. reached on an infield single to load the bases with two outs before Angels manager Ron Washington brought in Hunter Strickland, who got Volpe to ground out on his first pitch.

The Yankees, who entered Monday third in the majors with 5.29 runs per game, have scored five runs in their last five games. They were 1-for-18 with runners in scoring position on Monday night and left 12 men on base.

Stanton went 2-for-4 with a double and a strikeout and Judge (1-for-3) became the first player in the majors to reach 100 hits this season.

“It’s great to be back,” Stanton said. “Yeah, obviously want to win. But yeah, it’s good to be back out there. I saw the ball pretty well, besides one at-bat . . . Just working on that, make sure my timing is geared up. Get rolling.”

Nolan Schanuel’s 66.3-mph RBI double down the leftfield line off Jonathan Loaisiga with one out in the top of the 11th gave the Angels a 1-0 lead. After getting the final two outs, Loaisiga angrily spiked the ball as he headed back to the dugout.

Clarke Schmidt, who did not factor into the decision, turned in his second scoreless start against the Angels this season. The righthander allowed four hits in 7 2⁄3 innings, striking out three and walking none. It was Schmidt’s longest start of the season and second-longest of his career. He retired 16 straight between the first and sixth innings and 22 of the final 24 batters he faced.

The last batter Schmidt faced, No. 9 hitter and Brooklyn native Moore, recorded his first career hit  in the eighth with a triple past Judge, who dove for the two-out hit rather than play it more conservatively.  Fernando Cruz entered and struck out Zach Neto to keep the game scoreless.

“I think you go through streaks like this where sometimes you’re mashing the ball and things are falling, and then sometimes things aren’t kind of going your way,” Schmidt said. “So part of the game, and obviously we play 162 for a reason.”

Angels starter Jose Soriano struck out six in seven innings and allowed six hits and a walk.

Stanton led off the ninth with a double off Kenley Jansen and Dominguez pinch ran for him. He attempted to steal third with one out but was tagged out  as Volpe hit a grounder directly into the glove of Rengifo while Dominguez was sliding in headfirst. Volpe, who reached on the fielder’s choice, stole second but was stranded there when Austin Wells struck out.

With Wells at second to begin the 10th, DJ LeMahieu bunted the first pitch foul and failed to advance the runner, striking out on four pitches. Trent Grisham and Goldschmidt followed with long flyouts.

Stanton received a standing ovation before his first at-bat, stepping up with men on second and third with two outs in the first inning. He swung at the first pitch he saw — a low-and-inside 95.7-mph sinker — and hit a 101.5-mph groundout to third.

He notched his first hit of the season in the fourth on the eighth pitch of a lengthy second at-bat, roping a full-count, 97.4-mph sinker to leftfield at 111.1 mph off the bat for a one-out single. His ninth-inning double had an exit velocity of 102.9 mph. 

“[Stanton] looks really locked in,” Schmidt said. “I think this is kind of like seeing him around here, moving around here, the way he’s kind of carried himself before the games and stuff. It felt a little bit like playoff G. Just very locked in and ready to go.”
