After battling a right toe injury for most of the second half of the season, DJ LeMahieu was left off the Yankees’ ALDS roster, as manager Aaron Boone felt the infielder remained “compromised” by the injury.

While Boone didn’t rule out LeMahieu for the ALCS if the Yankees advance past the Guardians, the manager also didn’t know if he would be healthy by spring training, given the unpredictability of such an injury.

LeMahieu will continue to see specialists in an effort to remedy the issue. Before the Yankees’ 4-1 Game 1 win over the Guardians, Boone said it still wasn’t clear if LeMahieu would need to have a procedure at some point or could just rest the injury.

A source told The Post’s Joel Sherman that LeMahieu has a foot fracture that is resonating into his toes, making it difficult for the foot to pivot.

LeMahieu has been dealing with some form of the injury since before the All-Star break, when he received a cortisone shot.

But he has been playing hurt for nearly the entire second half — and has been severely limited since August, when he had to be shut down while the Yankees were in Boston.

He participated in a workout Monday at the Stadium, taking batting practice and running the bases, and his movement was clearly impacted.

“Watching [Monday] was similar to Texas,’’ Boone said of the Yankees’ final regular-season series, when LeMahieu came off the injured list and went 4-for-16, but didn’t look like his usual self at the plate.

“He was a shell of himself,’’ Boone said. “He understood. It’s hard.”

That was enough for Boone to bring LeMahieu in and tell him he wouldn’t be on the roster, though the infielder said he thought he’d be able to provide an at-bat off the bench, according to the manager.

“I just felt like it wasn’t the responsible thing to do,’’ Boone said. “I appreciate all that he’s been through and all that he’s been trying to try to make it work. We’re leaving the door open as far as moving forward, hopefully, if we get deeper in the playoffs. But right now I just felt like he was compromised too much.”

As for whether the effects of the injury will spill into next season, Boone said: “We’ll see. I don’t know if it’s rest [that heals the injury] or a procedure.”

LeMahieu hasn’t had an extra-base hit since early August.

Since signing a six-year, $90 million deal prior to last season, LeMahieu has not been healthy in the postseason.

Last year, a core muscle injury sidelined him late in the year and prevented him from being on the Yankees’ roster for their wild-card loss to the Red Sox at Fenway Park.

LeMahieu returned in good form this season and provided Aaron Judge with some assistance in the lineup.

He had an OPS of .827 on Aug. 7, which is also when LeMahieu had his final extra-base hit of the season.

Without LeMahieu, Josh Donaldson will play regularly at third base. Second baseman Gleyber Torres, who missed the final week of the season with flu symptoms, was playing well before he got sick.

Anthony Rizzo will be at first base, with Isiah Kiner-Falefa at shortstop, backed up by Marwin Gonzalez, as the veteran got the nod over rookie Oswald Peraza.
