Yankees decide how long struggling Anthony Volpe’s benching will last: ‘It’s all on me’

Anthony Volpe’s slump landed him on the bench Sunday night against the Red Sox, and he was told he won’t be in the lineup Monday against Washington.

“I just found out,’’ Volpe said after a 7-2 win over the Red Sox of being informed he’d be out of the lineup for a second straight day — again with a right-handed starter on the mound — before he’s expected to return Tuesday versus Washington lefty MacKenzie Gore.

“It’s pretty raw,’’ Volpe said of the news. “As a competitor and someone who takes pride being out there every day, you take it on the chin and look at the positives. … It’s all on me.”

Prior to Sunday’s victory, Aaron Boone said he chose to sit Volpe for the series finale because Volpe has “scuffled a bit over the last week [or] 10 days.”

The manager also pointed to the presence of José Caballero, who provides the Yankees with another solid option at short.

Asked if Volpe would start on Monday when the Yankees host the Nationals, Boone said, “We’ll see.”

Volpe entered Sunday’s game for the top of the eighth, when Caballero was shifted to right field to replace Giancarlo Stanton.

The shortstop has found himself the target of fans recently, especially during his current 1-for-28 stretch that began when the Yankees started a road trip in St. Louis on Aug. 15.

He also made a throwing error in Saturday’s loss to Boston and a mental miscue when he threw behind Jarren Duran to try to get him at second base — rather than make the routine play to first — in Friday’s defeat.

It’s part of what’s been a disappointing season for the 24-year-old, who has taken steps back on both offense and defense in his third year in the majors.

“Just continue the work,” Volpe said. “There’s so much good work being put in. That’s what makes it frustrating. You feel like you can contribute and help the team, but it’s not discouraging because you know the work you’re doing. I’ve got to do what I’ve got to do to contribute. It’s obviously frustrating.”

His struggles have left him with some of the worst numbers in the majors — and now out of the lineup for two straight days — while healthy.

“As a competitor and someone where that’s all I’ve known, you take it on the chin,’’ Volpe said. “I’ll take advantage of any opportunities I can [get].”

He acknowledged the results are “bad.”

“The numbers are what they are,’’ Volpe said. “I don’t think you’re defined by them. Every night, you take it as it is. You either feel good about how you contributed [or not] and there are too many days I don’t.”

Boone said he doesn’t believe Volpe has been impacted by the harsh treatment from the crowd and his struggles.

“I think he handles it quite well,’’ Boone said. “I don’t think he’s overly affected by those things. He’s just a young player who works his tail off. He’s super-competitive and trying to find the next level of consistency in his game offensively. Mentally, he’s very tough and totally wired to handle all the things that go with being a big-leaguer in this city and being a young big-leaguer that’s got a lot of expectation.”

Others aren’t as convinced.

“He’s definitely taken a step back on defense and I don’t know if that’s a result of him not hitting well or being booed,’’ the AL scout said. “He showed a lot last year when he did what he did in the playoffs, but he’s gone right back to the same things he did wrong during the regular season.”

But it’s Volpe’s performance in the field that’s more worrisome to some scouts.

“He’ll get back to a hot streak at some point, but the fielding is a concern,’’ another AL scout said, referencing the 11-game stretch Volpe had in late July and early August in which he had seven extra-base hits. “I think he’s gone backwards both last year and this one.”

Defensive metrics can be unreliable, but most agree that Volpe is having his worst year in the field as a major leaguer.

Volpe has been valued for his ability to play every day, but Boone noted the addition of Caballero from Tampa Bay at the trade deadline gave the roster more flexibility.

Boone also insisted Volpe was fully healthy.

But his late season swoon isn’t new. Volpe has an OPS of just .458 in September, likely a product of the impact of a long season — before his breakout last October in the playoffs.
