Enjoy Jacob deGrom’s brilliance now with his Mets future uncertain

Jacob deGrom is so good when he pitches, opposing batters are amazed and admiring fans are agape. But let’s enjoy him while he’s here, because there’s no guarantee he’ll be here past this year.

“Pretty much the best, maybe the best to ever pitch,” Dodgers superstar Mookie Betts said after deGrom and Co. beat LA, 2-1, and gave Mets faithful at Citi Field one of the best baseball nights of the year.

DeGrom’s a sight to behold, all right, unless you happen to be standing in the batter’s box. He hit 102 mph last night, 95 mph on the slider. It was on one of those mid-90s sliders from the two-time Cy Young winner that Betts, the former MVP, hit out for the Dodgers’ lone run.

“A mistake,” deGrom called it.

But there was mutual admiration for Betts.

“You want to compete against the best,” deGrom said after baseball’s best pitcher beat baseball’s best team. “Mookie is having a great year with the numbers he’s put up.”

That deGrom is the best isn’t really up for debate now, at least when he’s out there. The question is about how long he will favor us with his genius — and, of course, what he will get on the open market, which is the only place we know for sure deGrom is headed next. And those questions remain unanswered (though I will attempt here to provide some financial guesses, anyway.)

Mets owner Steve Cohen did repeat his desire to keep deGrom on The Post podcast “The Show.” Cohen said, “Obviously, he’s been a great Met, and somebody we would love to have back.”

To deGrom the only thing worse than tipping pitches is tipping his hand. He’s not about to do it. Told of Cohen’s nice comment, deGrom only said, “We’ll cross that bridge when we get there.”

The man is as disciplined as he is talented. He may throw one over the heart of the plate every once in a great while (that was the “mistake” to Mookie), but he isn’t giving an inch. This should be one of the most interesting negotiations ever, with one of the more intriguing outcomes.

To start the guessing game, I conducted an informal, completely unscientific poll in the middle innings of deGrom’s latest gem — he allowed just three hits and the run, and struck out nine over seven innings — and the answers were all over the place, as you’d expect, for a pitcher who’s inarguably the best in the game, but sometimes only appears sporadically.

I sent texts to 12 baseball people, and nine responded (I’ll consider the other three asleep). A few cited the obvious recent comp, the $130 million, three-year deal for teammate Max Scherzer. In ascending order, here are the answers.

“33-42M per year for 2 to 3 years.”

“2-3 years, $35-45M.”

“Scherzer money but maybe only two guaranteed years.”

“Scherzer territory.”

“If he finishes healthy/elite … a [Trevor] Bauer/Scherzer shorter deal with huge AAV”

“4 times 42 plus vesting option to go to 210”

“Have to start at the Scherzer AAV right?”

“3 for 145”

“Whatever the best pitcher in baseball is worth”

“1 billion dollars”

That last one may not be serious, but his point was clear: No one compares. (“I don’t think anybody does,” Betts said). When deGrom is pitching, anyway.

It’s a show every time he starts, usually quite a good one. He doesn’t need much help, and often doesn’t get it. But this time he did. Brandon Nimmo went over the center-field wall to take a homer away from ex-Met Justin Turner. DeGrom raised his fists in glee. Then he tipped his cap for the play of the night. “Awesome,” deGrom called it later.

Closer Edwin Diaz, with Timmy Trumpet here to play the stirring “Narco,” closed out the game and sent the fans home happy.

Scherzer provided a different kind of help, as his record deal should propel very top pitcher deals even higher. Though starters don’t go as far as they used to — even great ones — there’s only a select few in the extreme elite category.

Asked whether his deal might help his teammate and some others, Scherzer responded, “I hope people beat it. In free agency every player contract is counted. It helps everyone. It’s a rising-tide effect.”

The question, too, is which way the tide is moving. DeGrom certainly hasn’t signaled whether he wants to return. He’s only said he intends to opt out of his current deal, which he plainly hates and has one year plus a club option year at $30.5 million to go. There’s been speculation about some of the southern teams for the right-hander from DeLand, Fla. The Braves and Rangers are often guessed, but the reality is that only a few can probably afford him.

Cohen called deGrom a “phenomenal Met,” and he’s been even more phenomenal than usual since his return. Through six starts now, his ERA is 1.98, his batting average against .136. He’s untouchable. Hopefully, that doesn’t apply to the Mets, too. But we just don’t know.
