There it was, as if waving from the flagpole behind the left field stands.

There it was, a five-pitch explosion in the seventh inning in the Bronx. It was the ultimate example of the power and glory that has defined the Yankees since Babe Ruth took up residence in New York 104 years ago.

Aaron Judge had already made history by hitting his 50th home run in the first inning, but Sunday’s game against downtrodden Colorado wasn’t quite the beach day you’d imagined. The Rockies couldn’t figure it out and were up 4-3 when Juan Soto came to bat with one out in the seventh inning.

He hit the first pitch from reliever Jeff Criswell deep into the right-field stands.

Judge followed suit, hitting the first pitch into the first row of the right-field stands.

Giancarlo Stanton was next. It took him three throws to pick one out and slam it into the net protecting Monument Park.

“A trifecta,” manager Aaron Boone called it after the 10-3 victory that gave his division-leading team its 17th win in the last 26 games. “Juan gets it going, Judge, he does what he does and G leaves no doubt.”

Two-three-four in the sequence is the new three-four-five. I’m not sure there’s ever been a deadlier three-four-five in baseball history. When Ruth batted third and Lou Gehrig fourth for the Yankees in 1927, Bob Meusel batted fifth. When Roger Maris batted third and Mickey Mantle fourth in 1961, Yogi Berra, Elston Howard and John Blanchard split fifth. When Joe DiMaggio batted third and Gehrig cleaned up in 1936, Bill Dickey was in charge of the five holes.

Now, we’re talking about Hall of Famers here. But in terms of pure wattage, power (and marquee power too) this feels unique.

When we talk about Ruth and Gehrig and DiMaggio and Mantle and Maris and Blanchard, we’re talking about the Yankees who won multiple World Series. When we talk about Soto and Judge and Stanton, the combined rings on their fingers add up to one — and Soto’s were won with the Nationals.

History is second only to winning in the Bronx. History is second only to winning for Judge, who became the first player since Ruth not linked to performance-enhancing drugs to hit 50 home runs at least three times in his career. He is on pace to surpass the AL record of 62 he hit two years ago.

“The biggest thing is we’ve got another game to play,” Judge said when asked about his ability to tune out the noise when he steps into the box. “The biggest and easiest thing is you want to be there to win the game. It doesn’t matter what you just did.

“It’s just something special when you touch home plate. Then you move on to the next one, you know? That’s what helps me stay focused on a game.”

Judge has hit 47 home runs in his last 102 games. He has hit 150 in the last three years, averaging a home run every 9.29 at bats. Ruth hit 161 home runs from 1926 through 1928. He hit a home run every 9.76 at bats.

The Yankees haven’t been as vulnerable behind Judge in the order since Stanton returned from a six-week absence in late July. There is some protection. Moving Gleyber Torres to the leadoff position has changed the dynamic. Torres, leading off for the ninth straight game, hit the Yankees’ fifth home run in the eighth inning to end the series.

But just as the home runs in the classic movie “Major League” were hit “too high,” the Yankees have also been thought to have hit “too many home runs” during many of their failed postseason runs since 2009. There’s always the question of whether the Yankees offense is diversified enough or whether better pitching will stop this display of muscle.

Baseball has become a playoff sport, like hockey and basketball. The Yankees have struggled in the postseason of late, as you may have noticed. That includes Judge, who went 1-for-16 in the ALCS loss to Houston two years ago and is hitting .211/.310/.462 with 13 homers and 66 K’s in 171 playoff plate appearances.

No. 99 is the Greatest Show on Earth, and no, I’m not talking about Wayne Gretzky. When only two people in history have accomplished that feat and the other is Babe Ruth, we can probably save 1-for-16 for another day.

On Sunday afternoon in The Bronx, Soto, Judge and Stanton took to the air with a bang, lighting up the sky.

Once in a Lifetime is there to be enjoyed.
