With a Mets starting rotation that has been put through the wringer, there has been one constant as of late and his name is Jacob deGrom.

Noah Syndergaard went down with a partially torn lat muscle. Then it was Matt Harvey.

Zack Wheeler. Steven Matz. Seth Lugo. The list goes on.

Every Mets starter has spent time on the disabled list except for deGrom and Robert Gsellman, the latter of whom was relegated to the bullpen at a point this season due to his struggles.

After suffering back-to-back losses where deGrom allowed 15 runs on 18 hits in just eight innings, the slumping right-hander took action and called upon Hall-of-Famer, John Smoltz.

DeGrom overheard Smoltz talking about the benefits of throwing two light bullpens between starts instead of just one when Smoltz was working as a commentator at Citi Field once.

“I talked to John Smoltz about it and he said he threw two bullpens for 10 years,” deGrom said. “It helps me feel comfortable on the mound, keep a feel for my command.”

And in command he was. In his last three starts, deGrom has scattered just two runs on twelve hits, while striking out 19. His ERA over that span is 0.72.

The lone blemish of deGrom’s masterful Saturday performance was a solo home run to Brandon Belt in the seventh inning which tied the game at one a piece.

The Mets would get the lead back the next frame to give deGrom and the Mets a lead they wouldn’t look back from.

“He’s just been lights out,” said Mets outfielder Jay Bruce. “That’s what an ace does, and it has come to the point now where I’m always wondering if he’s going back out in the ninth inning to finish the game. It’s really special. You really don’t get that from a lot of guys.”

On top of his recent string of dominance, deGrom added another notch in his belt for success during day games.

Since 1913, deGrom’s 1.69 ERA is the lowest for qualifying pitchers (min. 200 innings).

With the win, the righty improved to 7-3 on the season and dropped his ERA down to 3.71, a number that is inflated due to his two poor starts at the end of May and early June.

“[DeGrom] is a good pitcher,” said Mets manager Terry Collins. “Once he got over the little blip he had, I think he is going to continue on, and I think he is going to have a real big year. We have got to make sure we take care of him. We don’t need anyone else going down.”

After Rafael Montero‘s start on Sunday, the Mets will drop back to a five-man rotation, meaning deGrom is slated to pitch again Friday at home against the Phillies.

With the Phillies the only team worse statistically in the National League East (24-49) there’s no reason why the good the times will stop rolling for deGrom.

With all the blows to our big guns one right after the other this season, there wasn’t much to be excited about.

Even deGrom, the healthy one, looked lost out there less than a month ago. It wasn’t pleasant.

But after making some minor tweaks and working with John Smoltz, deGrom is back in his vintage form, and oh boy, it’s so good to see.

As Jay Bruce said, every time he’s on the hill now, you are wondering if he’s going to go out there for the ninth inning to complete the game.

Since deGrom burst on the scene in 2014, you knew the Mets had something special and for him to get back to his ace form, it’s a silver lining to how much of a roller coaster this season has been.
