NEW YORK — An overturned call at the plate in the eighth inning led to the latest loss in what’s become the New York Yankees’ worst season in decades.

Justin Turner hit a ninth-inning RBI double as the Boston Red Sox beat New York 6-5 on Sunday, extending the Yankees’ losing streak to eight, their longest in 28 years.

“We got to be unbelievable the rest of the way,” Yankees Manager Aaron Boone said after the Yankees dropped to 60-64 and fell nine games behind Seattle for the AL’s last wild-card spot.

New York appeared to break a 5-5 tie in the eighth when Isiah Kiner-Falefa scored from first on rookie Anthony Volpe’s single. Plate umpire Junior Valentine signaled safe, ruling Kiner-Falefa’s left foot got in ahead of Connor Wong’s tag, but the call was reversed in a video review, which also upheld the catcher did not block the plate in violation of rules.

“I got the go sign, went in there,” Kiner-Falefa said. “I didn’t feel like I had a lane. I think the rule is if you’re catcher and you’re over the foul line it’s considered blocking the bag right there. The ball did beat me but I didn’t feel like they had enough to overturn it.”

Kiner-Falefa took off from first right before Volpe made contact. He raced home after left fielder Rob Refsnyder slipped before making the throw to shortstop Trevor Story.

“From the get-go I thought he was out,” said Boston Manager Alex Cora, who had been ejected two innings earlier for arguing a called third strike and watched the key play from the clubhouse. “I was wondering why Junior was waiting. He waited, waited to call him safe and I was like what is he doing.”

Swept in consecutive series by Atlanta and Boston, the Yankees have lost eight straight for the first time since Aug. 19-26, 1995 when Buck Showalter’s final team fell to 53-58 before finishing 26-7 to get a wild-card spot,

New York, in danger of ending its streak of 30 consecutive winning seasons, is 24-39 since June 4 – the day after slugger Aaron Judge tore a ligament in his right big toe at Dodger Stadium.

“Every loss at this point is tough,” Volpe said.

Turner had four RBI for Boston, which is 8-1 against the Yankees this year and has won seven in a row against New York.

“They just got the better of us,” Kiner-Falefa said. “I feel like they’re swinging the bats well. They have a good game plan pitching. They’re just better than us right now.”

With the score 5-5, Pablo Reyes singled off Clay Holmes (4-4) leading off the ninth and stole second, and Alex Verdugo walked. Turner doubled to the right-field warning track on a sinker.

“He’s a good hitter,” Cora said. “He’s a great a leader and I’m glad he’s playing for us.”

It was Turner’s first hit this season that gave the Red Sox a lead in the ninth or later and the 16th of his career. Turner is hitting .372 with runners in scoring position in his first year with Boston following a decade with the Dodgers and is batting .395 against the Yankees.

“That had a real playoff feel, especially in those last three innings the back and forth and the fans were into it,” Turner said. “It was good to get that win.”

The Red Sox swept a series in the Bronx for the second time in three seasons. Boston won for the eighth time in 11 games and remained three games behind Seattle.

Chris Martin (4-1) allowed two hits in a scoreless eighth, and Kenley Jansen got his 29th save in 32 chances. Greg Allen doubled leading off the ninth and DJ LeMahieu was hit by a pitch, but Jansen struck out Judge and Torres, then retired Ben Rortvedt on a flyout.

“For a decade long, I’ve seen Mr. Clutch do his thing,” said Jansen, Turner’s longtime Dodger teammate.

Rafael Devers homered in the first off Clarke Schmidt and scored on Volpe’s throwing error, but Kyle Higashioka and Gleyber Torres hit tying homers in the third and sixth off Nick Pivetta. New York has been outscored 17-0 in the first two innings over its past five games.

Turner hit a three-run homer in the seventh off Michael King, one pitch after Devers was walked intentionally. Volpe tied the score in the bottom half with his 17th homer, a three-run drive against John Schreiber. Torres and Volpe reached 50 RBI; before Sunday, the Yankees were the only big league team without anyone reaching 50.
