On Friday night, the Yankees produced only four hits against one of the worst pitching staffs in the big leagues.

But they were bailed out by their own pitchers, starter Will Warren and the four relievers who followed him, who threw a combined shutout.

No such luck Saturday.

Clarke Schmidt paid for two of the few mistakes he made — both of which resulted in home runs — and the Yankees followed Friday’s futile performance at the plate with an even worse one, picking up three hits in a 7-0 loss in front of 46,084 irritated fans at the Stadium.

“We’re going through it a little bit right now,” said DJ LeMahieu, who had an infield single as the Yankees were shut out for the fourth time in the last 13 games and had their AL East lead over the second-place Rays cut to a half-game.

The Yankees (47-35) have lost 10 of their last 15, and their offense — or lack of it — has played a significant role in the slump. LeMahieu, in an 8-for-41 (.195) slide, is among many going through, as he said, “it.”

There’s Anthony Volpe, who is 7-for-51 (.137); Austin Wells, who is 9-for-49 (.184) and, most notably, Aaron Judge, who is 9-for-51 (.176).

“We haven’t performed our best the last couple of weeks,” Paul Goldschmidt said.

Goldschmidt put himself right at the head of that list. Blistering hot the first two months, he is 12-for-81 (.148) in June. “That’s hurt our team the way I’ve played this month,” said Goldschmidt, whose sixth-inning single snapped an 0-for-20 streak.

Cody Bellinger had the other hit, a first-inning line drive to leftfield on a 2-and-2 pitch from lefthander JP Sears on which he cut down his swing and at least showed a good two-strike approach.

The Yankees also have had their share of defensive miscues recently. The latest was a Keystone Kops-like eighth inning on Saturday.

After Allan Winans walked Brent Rooker and Nick Kurtz with none out, Max Muncy popped up a sacrifice bunt between Winans and catcher Austin Wells. It dropped in, but it likely would have spun foul if Wells had not picked it up. He still had an easy play at third as Rooker had to freeze on the pop-up, but Wells never looked there. With no chance to get Muncy at first, he made an off-target throw to first to load the bases.

“It’s in no-man’s land, but it’s a pop-up, so you’re probably going to have a play at third,” Aaron Boone said. “Had no problem with Wellsy picking it up there, but the play’s at third base.”

After a sacrifice fly by Tyler Soderstrom and a strikeout, Austin Wynns lined an RBI single to center. Bellinger’s throw to third got by Jazz Chisholm Jr. and Winans wasn’t in position to back it up, allowing a second run to score to make it 7-0.

Schmidt, mostly solid over six innings, ran his scoreless-innings streak to 28 1⁄3 innings before Rooker’s 17th homer, a one-out shot in the fourth, gave the A’s a 1-0 lead. Schmidt allowed four runs and four hits, the biggest of those Kurtz’s three-run shot in the sixth that made it 4-0. Kurtz has 12 homers, including 11 in his last 22 games.

Schmidt (4-4, 3.09), removed from his previous start against the Orioles after seven no-hit innings because he had thrown a career high-tying 103 pitches, issued four-pitch walks to Lawrence Butler and Jacob Wilson to start the sixth. After striking out Rooker, he threw a 1-and-2, 91-mph cutter on the inside of the plate in Kurtz’s wheelhouse.

“I thought the sixth inning was bad pitch selections,” Schmidt said. “Just fell into patterns. Very frustrating to put myself in that position. I was making quality pitches, obviously didn’t execute the first two hitters, throwing eight straight [balls] or however many it was . . . [got] Rooker there to get me back in the inning and then made some terrible pitch selections to Kurtz.”

The A’s (34-51), who toted a 5.41 team ERA into the day — second only to that of the Rockies (5.56) — have seen their pitchers get well the first two games of this series. Sears, dealt away by the Yankees as part of the ill-fated Frankie Montas deal at the 2022 trade deadline, came into the day 5-7 with a 5.44 ERA this year and 0-4 with a 5.77 ERA in six career starts against his former team. He allowed two hits and three walks in 5 2⁄3 innings.

LeMahieu remains confident that the Yankees’ offense, which still leads the American League in most categories — including homers (122), OPS (.783) and runs per game (5.06) — soon will emerge from this skid.

“I saw it the first two months,” he said. “It’s a long season. I hate saying that because you want to win every game. But I know we’ll be fine. We just have to keep going, keep getting better.”
