Travis d’Arnaud’s return date from a rotator cuff strain remains unclear as the catcher continues rehabbing at home in California with a personal physical therapist/trainer , but his agent, Joel Wolfe, told The Post that he anticipates the 27-year-old will be back working with the team in the next few weeks.

A definitive plan hasn’t yet been set for where d’Arnaud will go next, but he would either go to New York, Triple-A Las Vegas or Port St. Lucie once he can resume baseball-related activities.

“I know it was envisioned he would only be here for a short stint, more in like the couple-weeks range, and if all goes we’ll just get him going and get him back out there soon,” Wolfe said. “He’s doing well. It’s just aggressive strengthening, range of motion because Travis really wants to get back out there and hit the ground running.”

D’Arnaud, on the disabled list since April 26, has rehabbed away from the team in-season in the past with the same trainer, and the Mets cleared his decision to do it at home.

“The Mets have a terrific training staff, but the issue is during the season their No. 1 priority is getting the active-roster guys ready to play every day, plus the team’s going on the road constantly,” Wolfe said. “Everybody just wanted Travis to have a little more consistent program every day given the spot he was in. Everybody thought it might be good, just for a short stint, to do a certain level of exercises and strengthening and [physical therapy] and then he’ll be cut loose shortly back to the Mets program.”

The Mets’ 7-1 lopsided loss to the Nationals could have been much worse if not for a Willie Mays-style over the shoulder catch by Gold Glove winner Juan Lagares.

With two runners on in the seventh inning, Daniel Murphy blasted a shot to deep center field, but Lagares robbed his former teammate of an extra-base hit with an incredible catch on the warning track with his back facing home plate.

“It was tremendous,” manager Terry Collins said. “The route he took, the ball must’ve drifted on him, must’ve had had some type of spin to it because it started to tail back on him and to be able to stay with that running in that direction is amazing. He is what he was two years ago. He is an outstanding center fielder.”

Steven Matz threw a bullpen session and is scheduled to start Friday against the Brewers. The 24-year-old southpaw’s turn in the rotation was skipped on Saturday in Colorado due to discomfort in his elbow. He received a cortisone shot on Monday and said he isn’t experiencing any problems.

Lucas Duda was on the bench for the second straight game, with the Mets facing left-hander Gio Gonzalez. Duda sat Tuesday due to back soreness, but he “felt so much better,” according to Collins, and was available to pinch hit.
