A one-legged hitter.

A walk-off World Series home run.

A Game 1 Dodgers victory was swept away from a stunned opponent, just one away from defeat.

Unlikely, impossible, did this really happen again?

Has Freddie Freeman just become Kirk Gibson, replaying the franchise’s greatest moment 36 years and endless heartbreak later?

It certainly sounded that way Friday night, when the ball popped off Freeman’s bat against New York Yankees pitcher Nestor Cortes in the 10th inning like a bunch of firecrackers.

That’s certainly what it felt like: The ball soared into the right-field pavilion as Dodger Stadium rolled and shook with a roar that could be heard as far away as Times Square.

It sure looked like it: Freeman waved his bat in the air like a magic wand before dropping it and stumbling around the bases as his teammates danced at home plate like they’d just won a championship.

It certainly seemed like Gibson 2.0 appeared when Freeman’s grand slam gave the Dodgers a 6-3 win that was insanely uncanny in its similarities to the franchise’s great World Series moment in 1988.

“Everything was the same outside of the fist pumps,” Dodgers manager Dave Roberts said.

Even the dagger delivered seemed to carry the same deadly weight.

In 1988, the mighty Oakland Athletics were so shocked by Gibson’s Game 1 explosion that they managed just one more win in a series that marked the Dodgers’ last championship for the entire season.

In 1988, the Dodgers were so enthusiastic about their hobbled hero that they played the rest of the series in his honor, forever inspired by Gibson’s surreal act of toughness.

On Friday, the Yankees felt the same devastation.

They wasted six one-run innings from starter Gerrit Cole. They wasted a huge home run from Giancarlo Stanton. They wasted a run in the 10th inning that was the result of two stolen bases and a fielder’s choice.

Like the A’s, they had this game. Like the A’s, they blew it. And like the A’s, they can be ready.

“Possibly the greatest baseball moment I’ve ever experienced, and I’ve experienced some great moments,” Roberts said.

It was perhaps one of baseball’s greatest moments in October, as it was the first walk-off grand slam in World Series history.

“It’s pretty amazing,” Freeman said.

When asked to compare the impact of this hit to Gibson’s, Roberts said: “I think we win three more games, that will be part of it.

History is going to repeat itself? History was already repeating itself.

Like Gibson, Freeman is dealing with a painful leg injury, in his case a badly sprained ankle that had limited him to no home runs and one RBI in the playoffs.

Like Gibson, Freeman has endured hours of treatment virtually every day and even missed three playoff games because it was thought he wouldn’t help the team.

Like Gibson, no one on the other team believed in him; the Yankees walked Mookie Betts intentionally after Gavin Lux walked and Tommy Edman singled and both runners advanced on Shohei Ohtani’s errant catch.

Freeman stepped up. First pitch. Tear. Wow. Ball disappears into the air. Freeman disappears into a crowd.

“It felt like nothing, it just felt like floating,” Freeman said. “Those are the kinds of things, when you’re five years old with your two older brothers and you’re playing Wiffle ball in the backyard, those are the scenarios you dream about… that’s the best thing that can happen out there.”

It capped a Dodgers breakout, with Blake Treinen eliminating Aaron Judge on a pop-out with two runners on base to end the ninth.

“Pure elation,” Roberts said. “You don’t see teams celebrating after a game, a walk-off like that, but I just think it was definitely justified.”

The Dodgers struck first with one out in the fifth, when Señor October Kiké Hernández lined just out of the reach of right fielder Juan Soto, bouncing the ball into the corner for a triple. Moments later, Will Smith lined a shot to Soto to score Hernández.

It took the Yankees just three batters to tie the game, with Soto leading off the sixth inning with a sharp single to left and, one of Judge’s three strikeouts later, Stanton crushing a hanging knuckle curve 400 feet into the left field corner for a two – run home.

The Dodgers then came back to tie the score in the eighth when Ohtani hit a ball from the center-field fence for a double and then raced to third when Gleyber Torres mishandled the relay. Four pitches later, Betts scored him on a line drive to tie the game and set up the heroics for Freeman.

Afterwards, Freeman was filled with so much adrenaline that he felt like he wanted to jump out of his skin.

“I want to go through this table and tackle all of you,” he said during his post-match press conference. “This is pretty cool. It’s going to be hard to sleep tonight.”

It was a fitting end to an evening that began with a tribute to the late Fernando Valenzuela. Three days after his death, in the Dodgers’ first game in his absence, Valenzuela filled Chavez Ravine with a force that culminated in Freeman’s explosion.

During a pregame ceremony, there were tears, a stunningly long moment of silence, his family standing on the third base line during pregame introductions, and a first pitch placed on the back of the mound next to where the number 34 was in painted it dirty.

Almost every time the video board showed a fan, that fan turned their back to the camera to show that they were wearing a Valenzuela jersey. Jack Flaherty, the Dodgers starter who gave up two runs in 5 ⅓ innings, even wore a Valenuzela jersey during the game.

As the commemoration ended, a chant swept through the stadium like a warm breeze from the border.

“Fer-nan-do! Fer-nan-do! Fer-nan-do!”

Ten innings later, that chant was replaced by a new cheer.

“Fred-die! Fred-die! Freddie!”

Somewhere Kirk Gibson was smiling.
