After being limited by the aftereffects of postseason core muscle surgery for most of this year, Starling Marte didn’t rule out having to undergo the same procedure again if he doesn’t continue to progress from the right groin injury that’s sidelined him for the past month.

Marte and the Mets have been encouraged by some of the improvement he’s made in the last week, when he saw a specialist in Philadelphia to address the issues with his lower body.

But if he doesn’t regain complete health, another procedure could be on the table.

Marte said through an interpreter Sunday the process of undergoing surgery for a second time would be “really frustrating” because it would impact him in 2024.

He’s still hoping to get back on the field at some point over this final month of the regular season.

“That’s the goal,” Marte said. “It’s something you have to think about, but the goal is to play. You want to avoid surgery and you do everything you can to strengthen [the area], but if they feel surgery is the course to go, that’ll happen. The main objective is to be able to go out there pain- free.”

Marte is in the second season of a four-year, $78 million deal and has seemingly been robbed of his power and speed after displaying both in ’23 when only Pete Alonso and Jeff McNeil had better seasons at the plate for the Mets.

He turns 35 next month and after putting up an OPS of .814 with the Mets a year ago, has just a .625 OPS this season and has played just 86 games.

Buck Showalter said with the way Marte has improved of late there’s a “potential [surgery] won’t be an option.”

But the manager acknowledged surgery is “not a good option.”

Marte is already dealing with scar tissue from the previous procedure.

“I think he knows how important this [rehab] attempt is to keep it from happening again,’’ Showalter said. “It seems to be working. We’ll see.”

And of being able to play games before the end of this season, as well as fully healthy going into next year, Showalter said, “I think there’s the potential to do both, we hope.”

Mark Vientos didn’t play Sunday after he was removed from Saturday’s loss with what Showalter called a sore right foot.

Vientos said he’s dealt with an issue with the foot for much of the season and that he’ll be able to play through the discomfort.

Showalter added he expects Vientos to be in the lineup against Nationals left-hander Patrick Corbin when the Mets open their series in Washington on Tuesday.

The right-handed Vientos and lefty-swinging Brett Baty are expected to split time at third base the rest of the way.

Baty, who — like Vientos — has struggled defensively, made an excellent bare-handed play to get Teoscar Hernandez to open the fourth.

The switch-hitting Ronny Mauricio entered the game 4-for-5 as a lefty versus right-handed pitching and then singled up the middle in the second off right-hander George Kirby.

Mauricio then swiped second, his second stolen base since being called up from Triple-A Syracuse
