The sun returned, and the shock remained.

No matter how many hours or days or months pass, the sight of Noah Syndergaard’s name in the boxscore, beside 10 runs (nine earned), three home runs, and three innings of work, will always be bizarre.

But far more troubling than Wednesday’s career-worst outing was the former All-Star’s assessment afterward.

“I’m sick and tired of not being super comfortable, and kind of unathletic, on the mound,” Syndergaard said said before the Mets’ 4-1 loss to the Cubs on Thursday night. “Something I’m trying to work on every five days.”

Before Syndergaard’s implosion, he had thrown a career-best eight straight quality starts while lowering his ERA from 4.68 to 3.71, but the right-hander — who turned 27 on Thursday — said he hasn’t felt nearly as dominant as it seemed.

“The numbers looked good, but in terms of being comfortable on the mound, I felt the same,” Syndergaard. “The Cubs just really exposed that.”

The comments came as a surprise to Mickey Callaway.

“It really didn’t seem that way,” the Mets manager said Thursday. “He had been pitching so well, but I’m sure everyone has a different feeling. If he felt that way, I’m sure there’s probably a reason. So I’m sure that [pitching coach] Phil [Regan] and Noah will continue to work to get himself comfortable.

“I know they’re out there working every day. When they have a bullpen session, it’s not just go out there and throw pitches, they’re trying to feel things and feeling inside is a big thing for a pitcher.”

“You gotta feel comfortable. You gotta feel like you’re in sync and in rhythm, and I think that’s something that every pitcher battles every time out. I want this perfect feeling, and it happens very few times. But you’re always searching for it. So I can understand what he’s saying, but everyone feels something different. When he dominated and looks great, he probably doesn’t feel as good as we might see. It’s never as good as we think it is. It’s never as bad as we think it is.”

Callaway had expected Brandon Nimmo to play a third straight rehab game with Triple-A Syracuse Thursday night, but the outfielder ended up a healthy scratch from the lineup.

Nimmo, who has been out since May 21 and is expected to rejoin the Mets in the next few days, has appeared in eight games since beginning his current rehab stint on Aug. 16, going 8-for-28 (.286) between Syracuse and Single-A Port St. Lucie. In Wednesday’s game, Nimmo played seven innings in the outfield, going 2-for-4 with a homer.

“We’ll keep it day-to-day. He felt good [Wednesday],” Callaway said. “We’ll just continue to check on him daily and get him to a good spot.”

J.D. Davis homered for the third straight game and the eighth time this month. Of Davis’ 18 home runs this season, 13 have come at Citi Field. … Pete Alonso went 0-for-3 with a walk, extending the majors’ longest active on-base streak to 24 games.
