Take that, Kirk Gibson.

Two pitches after fouling a ball off his left ankle and writhing in pain on the ground, Aaron Hicks got the Yankees into the playoffs by drilling a one-out double down the left field line to score Didi Gregorius from first base with the winning run in a 3-2, 11-inning victory over the Orioles.

Coupled with the Rays’ loss to the Blue Jays earlier on Saturday, the victory clinched a wild-card spot and the Yankees will be going back to the postseason for a second straight year.

“I knew I had one good swing,’’ Hicks said in the celebratory clubhouse. “My ankle is still throbbing right now, but out there, it was all adrenaline and I wasn’t coming out.”

Gregorius started the rally with a leadoff single to right off lefty Paul Fry. Giancarlo Stanton struck out before Hicks, who appeared to be in serious pain after the foul ball, recovered and ended the game.

“For a minute there, I wasn’t sure if he was gonna be able to finish the at-bat,’’ said Aaron Boone, who went out, along with trainer Steve Donohue, to check on Hicks. “I think he was just being dramatic, maybe.”

Boone was kidding, but the Yankees certainly provided drama on Saturday. They were unable to score against the woeful Orioles for eight straight innings before they broke through in the 11th.

The next step for the Yankees is making sure the Oct. 3 wild-card game is played in The Bronx. The Athletics still are chasing them for the top wild-card spot.

“We found out last year how big home-field advantage can be,’’ Hicks said of the Yankees’ run to Game 7 of the ALCS, in which they lost to Houston in seven games.

After the Yankees took a 2-0 lead on homers by Hicks and Luke Voit in the second inning, Lance Lynn allowed runs in the third and fifth, as Baltimore tied the game.

Lynn made a good defensive play after Gary Sanchez’s passed ball and throwing error cost him an unearned run in the third. Lynn covered home plate and made the tag to get Steve Wilkerson after a strong throw from Gleyber Torres.

Chad Green, Aroldis Chapman, Dellin Betances and Zach Britton pitched scoreless innings before Jonathan Holder loaded the bases with one out in the 10th, but then got Chris Davis to line to first — where Voit made a nice grab — and got Breyvic Valera on a pop to second to end the threat.

The Yankees didn’t score again in the bottom of the inning, but Tommy Kahnle got the Yankees through the 11th, setting up Hicks’ heroics.

Gregorius started the rally with a leadoff single against lefty Paul Fry. Giancarlo Stanton struck out before Hicks came to the plate and fouled a pitch off his ankle.

When he got up and sent a rocket down the line, Gregorius had one thought: “I wanted to go all the way and try to score no matter what. I put my head down and started running.”

Aaron Judge watched from the dugout.

“Right when Hicks hit it, we were all yelling, ‘It’s over, it’s over,’ ” Judge said.

For the Yankees, though, their mission has just begun.

They finished last season on a 20-8 run. With Saturday’s win, they improved to 12-12 since completing a four-game sweep in Baltimore on Aug. 26.

“We’re not done yet,’’ Judge said. “We’ve still got a lot of work to do. This is just the first step. … Our main goal is always to win a World Series, so we’re going to keep chasing our goal.”

Boone wanted his team to celebrate the win before getting back to work Sunday.

“I think everyone in that room understands we feel just as capable as any other team of doing something special,’’ Boone said. “We’ll appreciate this tonight and go back to the task at hand and make sure we play a home game to start things off.”
