BOSTON — Perhaps the Yankees would have been better off if it had just kept raining.

After Saturday’s washout followed Friday’s stinker, the Yankees did not snap out of their funk on Sunday afternoon, falling in the first game of a doubleheader, 6-2, to the Red Sox at Fenway Park.

After taking a 2-0 lead to the fifth inning, things quickly unraveled for the Yankees, with the Red Sox getting to Clarke Schmidt for a pair of runs before the usually dependable Michael King blew a tie game in the sixth.

The Yankees’ offense, meanwhile, continued to struggle without Aaron Judge.

They mustered just four hits — only two after the first inning — against the Red Sox (36-35), who breezed through a bullpen game.

It resulted in the Yankees (39-32) losing for the seventh time in their last 10 games entering Sunday’s nightcap, with their tailspin coinciding with Judge’s absence.

“That’s the storyline, so we’re going to get beat over the head with that,” manager Aaron Boone said between games. “The reality is that team we’re rolling out there is capable of doing damage offensively. And even more capable obviously with Judge. You take the best player in the world out.

“That, to me, is just an excuse right now. We got plenty of guys capable of putting up big runs. I know it’s going to be the story every day until we start banging away. But we got more than capable people to get it done. We just gotta get a little more consistent right now.”

The bats that the Yankees need to be their biggest have all gone dormant at the worst time. Giancarlo Stanton entered the nightcap 5-for-38 (.132) since coming off the IL.

DJ LeMahieu was 15-for-90 (.167) over his last 24 games.

Even after scraping a single in the ninth inning of Game 1, Anthony Rizzo was 4-for-45 (.089) since missing three games with a stiff neck.

And Josh Donaldson was 4-for-30 (.133) with three home runs since coming off the IL.

“I think usually these types of things do stem from trying to do a little bit extra when a guy like Judge is out,” hitting coach Dillon Lawson said between games.

“These types of stretches, they’ll beat you up. But you gotta have confidence. You gotta have trust. And you’ve got to believe in the things that you do well.”

After coming on for Schmidt to record the final out of the fifth inning, King got two quick outs in the sixth before the Red Sox got to him for four straight hits, peppering the Green Monster to take a 5-2 lead.

Enrique Hernandez got it started with an infield single to first base before Connor Wong roped a double off the Monster just out of the reach of a leaping Jake Bauers.

Hernandez scored all the way from first, though a potential close play at the plate was wiped out when Rizzo cut off the relay throw home to Jose Trevino.

“The ball was really dying, so our angle, it wasn’t gonna [be a one-hop to Trevino],” Boone said. “That said, to me it was gonna be a close play. And probably with the guy going back [to second base], probably one we should let go. But not sure one way or the other. I do feel like it was gonna be close.”

Alex Verdugo then followed with another double off the Monster before Justin Turner lofted a single to left-center to make it 5-2.

The Yankees never threatened to mount a comeback.

After Bauers doubled and Gleyber Torres homered in the first inning, the Yankees did not record another hit until Bauers led off the sixth inning with another double.

“We gotta win games regardless [of whether or not Judge is playing],” Stanton said. “Obviously it’s a big blow for us, but we gotta figure out how to win games. That’s the situation we’re in, so can’t have excuses.”
