BOSTON — Finally, there appears to be a specific timeframe for Giancarlo Stanton’s return to the Yankees.

Before Saturday night’s game against the Red Sox, manager Aaron Boone said his expectation is that Stanton, out all of spring training and the first 2 1/2 months of the season with tendon tears in both elbows, could be back “Monday or Tuesday.”

The Yankees will start a four-game series on Monday night against the Angels at the Stadium.

Stanton has spent the last week with Double-A Somerset getting at-bats as the designated hitter. He was in the Patriots’ lineup on Saturday night, though that game was imperiled because of weather concerns.

Regardless, in a conversation with Stanton earlier in the day, Boone said his takeaway was that he felt just about ready.

“He feels good,” Boone said.

Speaking about Stanton on Friday, Boone all but said the final call regarding his return would be the player’s.

“I think [for] the training staff, he’s kind of checked the boxes now, especially all of the running progression he’s done the last few weeks and the amount of live at-bats that he’s logged,'' Boone said. "The biggest say is probably Big G’s now.”

All indications are Stanton is about set to give himself the green light.

During the first eight years of his career with Atlanta, Max Fried started only twice against the Red Sox. Both games were at Fenway Park, where the lefthander went 2-0 with a 3.00 ERA. One of those games took place during the COVID-19-shortened 2020 season, when there were no fans at any big-league ballpark.

Fried, slated to face the Red Sox for the first time as a member of the Yankees on Sunday afternoon, is pumped to get his first in-game taste of the rivalry, especially doing so at Fenway.

Fried, much like injured Yankees ace Gerrit Cole, is a fan of throw-back ballparks such as Fenway and Wrigley Field.

“It’s almost like a time capsule into the history of baseball,” said Fried, 9-1 with a 1.84 ERA this season. “You see the seat where Ted Williams hit that homer out there [a singular red seat in the deep rightfield stands] . . . You don’t get that often, so when you get the opportunity, you try to make the most of it and take it in.”

Fried signed an eight-year, $218 million free-agent contract during the offseason to pitch for the Yankees, who beat out a handful of other teams pursuing him aggressively, including the Red Sox.

“They were really motivated to kind of turn around the last couple of years [in which they didn’t win],” Fried said of the Red Sox. “I was definitely impressed with the organization and meeting with people over there. Obviously, I’m over here. It’s that balance of I wish them the best, but I’m a Yankee, so not too much.”

Boone said righty reliever Jake Cousins, who started the season on the injured list with a right elbow flexor strain and who recently was  diagnosed with a UCL injury that paused his rehab, is “moving toward” having to have Tommy John surgery but “I don’t think that’s been finalized yet.” Cousins posted a 2.37 ERA in 37 games with the Yankees last season . . . Boone said Luis Gil, on the IL since the season’s start with a right lat strain, is “probably 10 days, two weeks” from throwing his first live batting-practice session of his rehab.
