The chatter around the Mets has been their schedule: From the release of next year’s slate to how soft their recent run has been.

Now it’s going to be how tough their stretch run is, starting Tuesday with a three-game road set at National League East-leading Atlanta.

“Yeah, for sure. I’ve already been thinking about it,” said Zack Wheeler, who’ll get the ball at 7:20 p.m. against Max Fried. “You lose [Sunday], we need to pick the momentum right back up and get that first win in Atlanta and get right back after it, set the tone. Set the tone with them.”

The Mets had been a white-hot 13-1 coming into this past weekend’s series against Washington, but their streak had been downplayed in some quarters because it came against soft competition. But the Mets are pointing to their series win over the Nationals as proof they can beat good teams. They’ll get an even better one in Atlanta.

“It was big, because we were running off all these games and winning them and everybody was kind of saying you were playing against easy teams, blah, blah, blah. Those are the games you’re supposed to win,” Wheeler said. “So you can’t blame us for winning them. You’re supposed to win those games.

“If you do, it’s a plus. If you don’t, then you look even worse. Playing those easier teams then coming up against, like, the Nationals, you knew it was going to be a tough test. But we pulled it out, we grinded, played good baseball for the most part.”

The Mets’ remaining slate includes: At the Braves, at the Royals, versus the Indians, Braves, Cubs, at the Phillies, at the Nationals, the Phillies, Diamondbacks, Dodgers, at the Rockies, at the Reds, the Marlins before closing against these same Braves again.

Their opponents’ .508 winning percentage represents a far tougher road than the Braves (.499) or Nationals (.498) have to face.
