Don’t blink! Thor to return for Syn-gle inning vs. Nats

Noah Syndergaard finally will return to active duty for the Mets on Saturday, but don’t arrive or tune in late if you hope to catch the former All-Star. Syndergaard will work only the first inning on Saturday against Washington, his first major-league appearance since he suffered a torn lat muscle on April 30.

“I’m going to be really happy to see him, especially after he comes out and Sunday morning he comes in and says, ‘Boy, I feel good,’” Terry Collins said before the game. “That will be a relief, and certainly what we’re looking forward to.”

Syndergaard, who will be followed in the game by previously scheduled starter Matt Harvey, tore his right lat in Washington nearly five months ago, one start after he’d declined the team’s request to undergo an MRI on a sore right biceps.

GM Sandy Alderson indicated that Syndergaard might pitch once more before the season concludes next weekend.

“This rehab process is both physical and mental,” Alderson said. “Our doctors have said that based on Noah’s feedback, he feels good physically. We just want to get him back on the mound, if for only a moment… so that he’s back out there, he’s

re-familiarized with the circumstances and he goes into the offseason with that little bit of additional confidence.”

Harvey, who has been rocked for a 13.19 ERA since returning from his own DL stint with a shoulder issue, initially had been bumped up from Sunday to Saturday, with Jacob deGrom pushed back to the series finale due to an illness.

DARK KNIGHT RETURN?

Asked if the Mets plan to tender a contract to the arbitration-eligible Harvey for next season, Alderson replied: “Do I expect to at this moment? Yes. At this moment, I favor the idea of him being back next season, yes.”

STAR POWER

Alderson has been impressed by the big-league indoctrination of shortstop prospect Amed Rosario, who returned to the lineup after missing three games with gastroenteritis that required hospitalization earlier this week in Miami.

“If he gets his strike zone under control, he can be a superstar. So I think that’s the impression that he’s made, not that he’s a ready-to-go All-Star player, but he has the tools and the potential to be an outstanding player,” Alderson said.

“And I think he has the ability to be an everyday player next season.”
