Right now, the only thing the Yankees and Luis Severino can agree on is that he’s got a Grade 2 lat strain and won’t be back in the rotation until July at the earliest.

Severino was at Yankee Stadium on Wednesday, a day after he met with general manager Brian Cashman, as the team tries to determine how the right-hander went from seemingly making good progress recovering from the rotator-cuff inflammation that sidelined him during spring training, and into the early part of the regular season, to being shut down with a “significant” strain of the latissimus muscle on his right side.

The Yankees ace said Wednesday he’s still not sure how the lat strain happened, and he believes it has been there since he was originally scratched from a Grapefruit League start March 5.

According to Cashman, though, the MRI exam performed that day showed no issue with the lat, and it was only when Severino was throwing from 120 feet on flat ground on April 8 and didn’t feel right that a test showed that injury.

“As you would expect, we’re walking through the process with the player,” said Cashman, who met with Severino in The Bronx on Tuesday. “I waited for him to come up here. We walked through it from his perspective, the trainers’ perspective. We’ll walk though it from the physical therapist’s perspective, the entire log, what he was doing, the progressions [made] without complaint.”

Cashman also stressed he’s not upset with Severino and is confident the pitcher has been honest about his arm, saying “medicine is an inexact science.”

“Part of treatment protocol is to treat the patient and treat the MRI and sometimes they don’t match up,” Cashman said Wednesday at the Stadium. “We’re trying to piece it all together. … Right now, I go into it with an open mind. I’m trying to determine how this happened. It’s a new injury. It’s a different injury.”

And while Cashman said he’s “not gonna be in position to provide a Mueller Report with, ‘These are my findings,’ but we’re going through the process, because it’s just highly unusual. Even the doctors said it.”

Cashman said it was possible that because athletes react to injuries and pain differently, Severino may have just not complained of discomfort. Still, a follow-up test on March 23 also didn’t reveal a lat problem.

“This normally is like a gunshot,” Cashman said. “At the end of the day, we have him down, and he’ll continue to get the care he’s getting. I’m not even ruling out that it’s not related to the first [injury]. I can just tell you what the MRI said.”

While Cashman plays detective, Severino said he is pleased to know what was bothering him, adding he doesn’t have a time frame in mind for when he’ll start for the Yankees for the first time this season.

“I just want to get healthy and help the team,” Severino said.

Realistically, Severino won’t be able to get back until July, since he’ll need to go through another spring training and can’t pick up a ball for another five weeks.

Asked if there were any positives to having Severino out longer, Cashman pointed to the fact the shoulder injury had healed by the time the lat issue popped up.

“There’s no silver lining in losing him for two more months,” the GM said. “We’ve got to get him going and he’s a starter, not like Dellin [Betances], who can get going quicker. … It doesn’t change the fact that he’s not gonna be available to us, and that is a problem.”
