Aaron Boone said he wanted to get as many left-handed hitters in the Yankees’ lineup as possible Sunday night against Red Sox right-hander Brayan Bello — and Anthony Volpe was among those who started the game on the bench.

But Volpe’s issues at the plate are bigger than having him avoid a tough righty. After he struck out swinging with the tying run on third base in the bottom of the 10th inning to end the Yankees’ 3-2 loss to the Red Sox, the rookie shortstop now has just one hit in his past 14 at-bats. His batting average is down to .186, the lowest it has been since April 15.

Before the game, Boone not surprisingly praised Volpe’s overall play — his power, in particular. His lack of production, however, could become an issue.

Volpe, who entered the game at short in the ninth inning after starter Oswaldo Cabrera was pinch hit for, has an OPS of .605, the worst it has been since mid-April. With Aaron Judge on the injured list with a sprained toe, Harrison Bader out with a right hamstring strain and Anthony Rizzo, who went 0-for-3 with a walk Sunday, slumping, the lineup doesn’t have much margin for error.

Boone said he remains confident the 22-year-old Volpe isn’t letting the rough time at the plate get to him.

“I do think he’s very much equipped to deal and handle it all in a lot of ways,’’ Boone said. “Even in his minor league career, for all the success he had, he struggled, too, along the way. It’s all part of this game, even for great players, dealing with ups and downs you inevitably face.”

To Boone’s point, Volpe got off to a rough start last year at Double-A Somerset, hitting just .183 with a .643 OPS in his first 38 games, along with 41 strikeouts in 171 plate appearances.

He bounced back, however, hitting .333 with a .929 OPS over his next 18 games, as he figured out Double-A pitching after he had split the previous season between Low-A Tampa and High-A Hudson Valley.

Volpe finished the 2022 season with 22 games at Triple-A Scranton/Wilkes-Barre before he showed the Yankees enough during spring training to win the starting job at shortstop.

Boone, general manager Brian Cashman and owner Hal Steinbrenner have preached patience with Volpe. On Sunday, Boone focused on the impact Volpe’s bat has had on the Yankees’ success this year.

“I look at it as he’s still productive,’’ Boone said. “He has nine homers [and] a lot of big hits. He’s done a lot of big things, a lot of winning things. Even if he’s hitting under .200, offensively speaking, he’s been in the middle of a lot of winning games. While he’s taken his lumps and had his struggles, he’s also had some massive successes.”

Boone pointed out that Volpe is on pace for more than 20 home runs and said he has the “aptitude” to overcome adversity at the plate.

“He’ll eventually get better and better at plugging holes [in his game] and make adjustments,’’ Boone said. “That’s who he is. I’m confident he’ll do that.”

The most logical replacement if the Yankees decide to make a move at short would be to call Oswald Peraza up from Triple-A. Peraza, however, was just 6-for-32 in a dozen games with the Yankees earlier this season following a promising 2022. And although Peraza has a .980 OPS in 22 games with SWB this season, he has cooled down recently.
