ST. PETERSBURG, Fla. — Not even Aaron Judge can carry the Yankees by himself.

A night after manager Aaron Boone said the Yankees should be “pissed off” and “embarrassed” about their performance Friday night in a shutout loss to the Rays, they were nearly as anemic at the plate, losing for the sixth time in seven games.

This one was a 2-1 loss that cut their lead in the AL East over second-place Tampa Bay to four games (just three in the loss column) as they were dominated by former Yankee Corey Kluber.

It’s their slimmest advantage in the division since May 11, when it was also four games.

Their only run came on a home run by Judge off Jason Adam to lead off the top of the ninth. That ended a Yankees scoreless streak of 21 innings.

“Well, we’re number one in the [American] League in scoring, as amazing as that is,’’ Boone said of the disappearing offense after the most recent defeat.

But even Boone acknowledged the offense has been an issue after the Yankees had three hits or fewer for the 13th time this season, the most times that has happened to them since 1914.

“If we don’t turn this around, that will be the story,” Boone said. “But we still have it in front of us. We have the people to do it. Injuries are a real factor, but everyone deals with that. You’ve still got to find a way to put points on the board. We’ve done a good job, [but] if we don’t dig ourselves out, you’ll have a great story.’’

With Andrew Benintendi on the injured list, it now seems that Judge is the only player in the lineup who can hit, so this offensive drought may not be over anytime soon.

Judge’s 52nd home run of the season matches his career-high, set in his rookie season of 2017.

More worrisome for the Yankees, who are 18-31 since their 61-23 start, is that they’ve also breathed new life into the Rays, who have won five in a row.

“It’s still ours,’’ Giancarlo Stanton said. “We’re not where we want to be, but we still [have] a fine opportunity, so it is definitely there for the taking.”

Tampa Bay is typically a tough opponent because the Rays play with good fundamentals. That was not the case Saturday, as they botched several plays in the field and ran the bases poorly throughout the game.

They gave the Yankees a chance to take an early lead when Yandy Diaz made a throwing error with one out in the first, allowing DJ LeMahieu to reach base.

Giancarlo Stanton followed with a bloop single to right that bounced over the head of Manuel Margot. LeMahieu moved to third on the play.

But with Josh Donaldson at the plate, Stanton tried to advance to second on a bounced pitch by Kluber, but Francisco Mejia got to the ball quickly and threw out Stanton for the second out.

Donaldson grounded out to keep the game scoreless.

They fell behind in the bottom of the third when Clarke Schmidt gave up a two-run single to Diaz. On a grounder up the middle, the ball hit Schmidt’s foot and bounced past Gleyber Torres at second, rolling into right field.

Kluber, meanwhile, continued to mow down the Yankees, on his way to seven scoreless innings. It was his longest start since his no-hitter with the Yankees last season.

After Stanton’s two-out single in the first, Kluber retired the next 14 batters, before Jonathan Aranda made a throwing error on an Aaron Hicks grounder with one out in the sixth.

Pete Fairbanks took over for Kluber in the eighth and retired the side in order. Adam finished it in the ninth after Judge homered, getting LeMahieu to pop out, then striking out Stanton and Donaldson.

Stanton, who went 1-for-4, but is still without an extra-base hit since his return on Aug. 25 from left Achilles tendinitis, took some blame for the team-wide slump.

“I need to be an impact and not have basically zero production,’’ Stanton said. “I need to be a boost here and not a blank spot in the lineup.”

Right now, there are plenty of blank spots.
