ATLANTA — The Mets have discussed a face-lift to the left side of their infield, but at this point a plan that would entail Jose Reyes and Asdrubal Cabrera switching positions has gained little traction, multiple sources told The Post on Thursday.

Cabrera, who is battling knee soreness that has limited his range, is against the idea of moving from shortstop to third base and club officials are hesitant to force the issue on a veteran player.

The proposed switch would mainly benefit the 33-year-old Reyes, a natural shortstop who has struggled at third base this season. Reyes would be considered an upgrade over Cabrera at shortstop, but there is a possible pitfall. Mainly, Cabrera has played only one major league game at third base and would be adapting on the fly without the benefit of reps at the position in spring training.

Last weekend, manager Terry Collins revealed that Reyes, who has struggled as the third baseman, “hates” playing the position. It’s an assertion Reyes disputes.

“Maybe he sees something that I look a little uncomfortable, but I don’t know why [Collins] would say that,” Reyes said before the Mets’ game against the Braves at SunTrust Park was rained out. “Some ground balls, I am not going to say I get confused, but it’s different over there. I get caught in between deciding whether to charge or wait back on the ball. But I am getting used to the position.

“I’ll do whatever they ask me to do. I went to spring training with the understanding I was even going to play the outfield, so whatever they need.”

At least one major league talent evaluator believes there is hope for Reyes as a third baseman.

“I think he will figure it out,” the evaluator said. “He always had a weakness throwing from different arm angles.”

Reyes became the third baseman in the second half of last season after arriving on a minor league deal following David Wright’s surgery for a herniated disk in his neck. Wright currently is on the 60-day disabled list as he attempts to regain arm strength after missing most of spring training with a right shoulder impingement.

The 31-year-old Cabrera’s drop-off defensively has been noticeable to major league talent evaluators. Some within the organization believe his knee is hurting more than Cabrera has admitted. Last season, Cabrera battled a strained patellar tendon in his left knee for most of the season. He spent 2 ½ weeks on the disabled list in August before returning to help spark the Mets’ lineup over the final month-plus.

Cabrera has extensive experience playing second base, but club officials seem hesitant to push Neil Walker, who has slumped at the plate, to play third base. Walker can become a free agent after this season and may resist a move that potentially would affect his value this offseason.

If Cabrera is going to have a future with the Mets beyond this season — the club holds an option on him for 2018 — it figures to come at another infield position, as the team awaits the arrival of top prospect Amed Rosario to play shortstop.
