Who’s going to play the part of Kevin Millar on Tuesday afternoon? Jazz Chisholm Jr.? Chisholm has Millar’s chattiness. Maybe it’ll be Gerrit Cole. Cole is a loud and ardent leader. He’s been known to take a bullet or two for a teammate or a manager.

Can the Yankees activate Nick Swisher for a day?

Swisher would definitely do it.

“Don’t let us win tonight. This is a big game. They’ve got to win because if we win, we’ve got Cole coming back in Game 5 and then Rodon will pitch Game 6 and then you can take that fraud stuff and put it to bed. Don’t let the Yanks … Win. This. Game.” 

Pounding the glove for emphasis on the last three syllables.

Twenty years later, it’ll take two things for the Yankees to be able to balance the scales of baseball justice. Twenty years after becoming the first — and still only — baseball team to squander a 3-0 lead in a best-of-seven, this would be a good time to channel those detested Red Sox and find something inside themselves starting Tuesday.

That’s when they will report to work down 3-0 in this, the 120th World Series. Their other ancient rivals, the Dodgers, merrily put them in that hole Monday by pouncing early thanks to Freddie Freeman and closing late thanks to a stout pitching performance from Walker Buhler and an ensemble of relievers on the way to a 4-2 win.

Now, they need to do the worst thing imaginable: close their eyes, bite down hard, swallow harder and … emulate the Red Sox.

“We’ve got to pull some inspiration from somewhere,” Anthony Rizzo said. “It’s happened before.”

The kind of confidence Millar and his mates had would be useful, sure. More important, the Yankees have to act as the Red Sox acted, which is a two-fold thing. First, honor the pledge of every manager who ever saw a team fall into an 0-3 hole, one that Aaron Boone reliably unleashed Monday:

“We’re trying to get a game tomorrow,” he said. “Hopefully we’ll go and be this amazing story and shock the world, but right now, it’s about trying to get a lead, trying to grab a game and force another one and then go from there. But we’ve got to get one first.”

The other is more obvious.

He wears 99 on his back and is hitting .083 in the World Series.

The Yankees need Judge to show up. Period. STAT, as they used to say on “ER.”

It’s no longer enough to say it’d be “nice” if he got on track. It’s no longer feasible to build an argument that the Yankees can somehow survive in this series by carrying Judge instead of the other way around. It’s past time to laud Judge for taking “good at-bats,” like the one he took in the eighth inning, a six-pitch walk off LA righty Ryan Brasier.

No. Not good enough.

The Yankees need more. They need Judge to get hot — and red-hot, if possible. David Ortiz is in the building; that was the biggest element of the Sox’s miracle 20 years ago. In Games 3 through 7, Big Papi had a 1.199 OPS. That included home runs in Games 4, 5 and 7 and nine of the most essential RBIs ever collected over a four-game stretch. He was Superman.

The Yankees need their Superman. Judge has gotten on those kinds of rolls dozens of times, rolls that defy explanation and take breaths away. Some of those times, they come straight out of a batting slump too.

The Yankees need that.

“He’ll come ready to go. He’s Aaron Judge,” said Boone, who sure wasn’t going to be the first to hop off that particular train. “Get on time and get one.”

Boone pondered a few massages to his lineup during the course of a 5 ½-hour flight home, from takeoff right on through having to fasten his seat belt, make sure he raised his tray table and ensure his seat back was in the upright and locked position.

He did one of those: subbing Jose Trevino in for struggling rookie catcher Austin Wells, 4-for-42 with 18 strikeouts in the playoffs. He thought of doing a few others, though he was reluctant to share them. One that would’ve been entirely defensible: swapping Judge and Soto in the order. If nothing else, just to get a new look.

“It’s the World Series, no,” he finally decided. “That’s our guy [Judge].”

Said Judge: “All it takes is one. One swing, one at-bat, one play, and everything changes for us. That’s the mindset you’ve got to have. One game.”

Yankees fans treated him warmly, as expected, and will do so Tuesday night, for sure, even after another 0-for-3, even as his postseason average frittered to .140. He’s running out of season now, and the Yankees are running out of time. Twenty years ago, in a similar predicament, David Ortiz backed up Kevin Millar’s vow with his bat.

The Yankees don’t need the vow. Just the bat. Judge’s bat. STAT, as they say.
