Gary Sanchez is making his Mets debut.

In a moment of déjà vu with a major twist, Sanchez was penciled in to start behind the plate for the home team in a Sunday afternoon MLB game in New York.

Two days after he was called up from Triple-A by the Mets, the former Yankees slugger got the nod to catch Max Scherzer and bat eighth in the lineup for the first game of a doubleheader against the Guardians.

“It feels good to be back here in New York after all those years,” Sánchez said through an interpreter before not playing in Friday’s series-opener. “It’s a different team, but it’s still the same city, so it’s exciting to be here.”

Sanchez was an All-Star in 2017 and 2019 but his career spiraled from there, leading to a trade to the Twins after the 2021 season.

He was released upon request from the Giants organization earlier this month without getting out of Triple-A.

His last MLB at-bat was on Oct. 5, 2022.

Rookie Francisco Alvarez has emerged as the Mets’ starting catcher with Omar Narvaez (strained calf) and Tomas Nido (dry eye syndrome) on the injured list.

But teams rarely use the same catcher in both ends of a doubleheader, which meant Saturday’s rainout essentially guaranteed that Sanchez would start one of Sunday’s games at Citi Field.

Sanchez is a career .111 hitter with one home run and five RBI in 12 games at his new home ballpark.

But he was swinging a hot bat for the Mets’ Triple-A affiliate in Syracuse, compiling a 1.014 OPS in 37 plate appearances since May 9.

“As long as I’m healthy,” Sanchez said, “I can do a lot of good things.”

Sanchez actually is getting a second chance to make a first impression on New York.
