The last Mets pitcher to win the Cy Young award says he is pulling hard for Jacob deGrom to receive the honor this season.

“I can’t be objective,” R.A. Dickey told The Post on Tuesday when reached by phone. “I want him to win it and I want it for the Mets. I want it for the fan base. I want it for him. He’s been consistently good for a long time. I am pulling for him, there is no question.”

DeGrom allowed two runs over seven innings in the Mets’ 5-3 loss to the Marlins at Citi Field and holds a major-league best 1.71 ERA. Tuesday was his 26th straight start of allowing three runs or fewer, breaking a single-season record that was set in 1910.

The Mets stopped playing meaningful baseball months ago, but now their most important game looms each time deGrom is scheduled to pitch.

It all sounds so familiar to Dickey, the veteran knuckleballer who was pitching for a team going nowhere in 2012 when he seized the spotlight and gave Mets fans a reason to care.

Dickey finished that season 20-6 with a 2.73 ERA, led the league with 230 strikeouts over 233 ²/₃ innings and easily topped his closest competition, Clayton Kershaw, in the NL Cy Young voting. Kershaw was 14-9 with a 2.53 ERA and 229 strikeouts over 227 ²/₃ innings.

The one strikeout that gave Dickey the lead over Kershaw? It came in Miami against Adam Greenberg, a career minor leaguer the Marlins signed to a one-day contract.

“It was his only at-bat all year, it was against me and that ended up being the one strikeout that let me beat Clayton Kershaw,” Dickey said. “Nobody really talks about that, but I thought it was pretty poetic. I beat [Kershaw] in strikeouts and wins and he beat me in ERA.”

From Dickey’s perspective, the 20-win season helped sway voters. His concern for deGrom is an 8-9 record for a team that has failed miserably in scoring runs for him.

Max Scherzer has 17 wins. Aaron Nola has 16 wins. Dickey wonders if deGrom can overcome that disadvantage.

“All his other metrics are there,” Dickey said.

If Dickey felt any pressure in trying to become the first Mets pitcher since Dwight Gooden to win the Cy Young award, he doesn’t remember it.

That was a season in which Dickey’s crowning moment came in his last home start, beating the Pirates for win No. 20, completing a rise from journeyman pitcher plucked from the scrap heap to Cy Young contender and then winner.

“I felt such a connection with the fan base there,” said Dickey, who was traded to the Blue Jays after the season in a deal that netted Noah Syndergaard and Travis d’Arnaud, among others.

“That place is funny, right?” Dickey said, referring to the Mets. “It can go the Jason Bay way or it can go the way it did for me. Thankfully I performed well while I was a Met. To win the 20th game in front of the home crowd, the last year I was a Met in a Cy Young year, that was probably one of the most special days of my whole life and partly because of the relationship I had with the fan base.”

Dickey wasn’t even aware of deGrom’s presence in the organization during that magical season. Matt Harvey captured many of the headlines after making his major league debut in 2012 and deGrom was still trying to advance beyond Single-A.

But over the years, Dickey — who last pitched for the Braves in 2017 — certainly became aware of deGrom.

Now the 43-year-old Dickey spends his days at home in Nashville, having resisted the temptation to pitch again; he says four teams called during the season to gauge his interest after he told the Braves not to exercise his 2018 option. But the lure of staying home with his family is too strong.

“For all intents and purposes I think I am done,” he said.

Tom Seaver, Gooden and Dickey have won Cy Young awards for the Mets. There is certainly room for another name.
