Aaron Judge stepped back in the Yankees’ clubhouse on Thursday and is expected to be back in the lineup Friday against the Astros. He insists he’ll be at full speed after missing two months with a left oblique strain.

“When I get back on the field, I’ve got to play,’’ Judge said after completing a rehab assignment with Triple-A Scranton/Wilkes-Barre on Wednesday night. “I’m not gonna try to baby it or go at 80%. We’re in the major leagues. You’ve got to be at 100%, so I’m gonna go at 100%. I’m ready to go, so I’m not worried about it happening again.’’

Judge will slide back into right field, but manager Aaron Boone acknowledged he won’t play him “four, five, six days in a row” to start.

“I’ll take it slow with him,’’ Boone said of Judge’s early schedule. “The one thing he hasn’t done is play a ton of games and, after being out six or eight week, we want to build him up smartly.”

Like Judge, though, Boone is confident the outfielder is over the injury, which was suffered on a swing during an April 20 game.

“We feel like he’s physically in a really good spot and has been now for a while,’’ Boone said. “He’s ready to go and he’ll impact us in a big way.”

Judge agreed he’s been fine for some time.

“I felt like right when I could start swinging, I could play in a game,’’ Judge said. “Then it was about getting the reps in.”

The Yankees’ offense has remained productive without Judge — as well as in the absences of Giancarlo Stanton, Didi Gregorius and Miguel Andujar, among others.

But on the same week they welcomed back Stanton from a left calf strain, which followed a torn left biceps and strained left shoulder, and acquired Edwin Encarnacion from Seattle, they are finally getting back to the lineup they envisioned when general manager Brian Cashman assembled the team.

“To see him walk through the doors earlier [Thursday], it was really good to see him, knowing he feels really good and knowing what he brings to the room,’’ Boone said. “It’s really good to have him back, and I can’t wait to get him back [Friday].’’

Adding Judge to the roster will force the Yankees to make another move, and though Cameron Maybin might seem like an obvious choice to go, since he might not have much of a role in the outfield, he can’t be optioned to the minors without going through waivers — where the Yankees would likely lose him to another team.

Maybin has been valuable since the Yankees acquired him from Cleveland, where he was with the Indians’ Triple-A affiliate.

“He’s been great,’’ Boone said of Maybin, adding the team would wait until after Thursday’s game before making any decisions regarding their roster.

For now, the Yankees are just pleased to have their right fielder back, and though the team has been hurt not just by injuries but by players suffering new ones as they’ve come back, Boone said that isn’t a concern with Judge. He doesn’t expect Judge to have to protect himself.

“I’m not treating it like that because we feel like really now for a few weeks, he’s been healthy and ready to go,’’ Boone said. “It’s just been building him back up as far as stamina, playing and the daily grind. It’s more like coming out of spring training. As far as health goes, I feel like he’s ready to let it rip.”

Judge added he would simply go through his “normal routine” in preparing for games.

“I’ve just got to make sure I’m warm,’’ Judge said. “That’s the biggest thing — that I stretch out the core and then be an athlete and got out and play.”
