Yankees legends and Old-Timers are high on a newcomer, shortstop George Lombard Jr.

George Lombard Jr. headed out to shortstop again Saturday in the best baseball park in the Bronx. The 21-year-old kid began to do this Tuesday night at Yankee Stadium, his eye-catching major-league debut, when he drove  a ball over the wall and gobbled up every grounder in sight.

And he did the same thing in this 5-4 win over Atlanta, becoming only the seventh player in franchise history to launch at least two homers in the first four career games and playing flawless defense. He owns at least one hit in all four, and there have been no errors.

A little earlier in the afternoon, the guys who used to play in this park or the old one across the street, ones who helped continue the winning tradition, walked out onto the field for the 78th Old-Timers’ Day.

Reggie Jackson, Willie Randolph, Ron Guidry, David Cone, Bernie Williams, Mariano Rivera and so many from the pinstriped past dating to the 1960s heard the soundtrack of cheers again.

Then some of them played in a 2 1/2-inning game, moving a little more slowly but honoring Yankees history with each step.

There was a question at this intersection of past and present: Is Lombard going to become a big star in New York?

“I don’t think there’s any reason not to think that at this point,” Cone told Newsday.

Indeed, several Old-Timers raved to Newsday about the attributes of this young guy, who’s batting .385 — 5-for-13 — with two solo homers and a 1.346 OPS.

Cone paid Lombard a high compliment, comparing him in favorable terms with a former great Yankees shortstop.

“Looks like a natural,” the YES analyst said. “It’s a rare player that can show up so polished, ready to go.

“I hate to draw comparisons, but [Derek] Jeter was that way. The first day he showed up, he was ready. No more seasoning that needed to happen. He just needed more reps up here.”

Lessons ahead

And that, of course, is what’s needed now for Lombard. Randolph sees big potential.

“I already said on my social media, because I was here for the first game and I saw him before the game, I said, ‘A star is born,’ ” Randolph said. “I shouldn’t have put that on him too quick.”

Because as far as that “big star in New York thing,” Randolph said, “I don’t want to put it out there yet like that because the game is hard . . .  But I think he’s strong enough mentally to grow through that.”

He loved Lombard’s debut homer and called his defense “sweet,” yet he knows there’s more to learn.

“But when I see his instincts, he’s going to learn how to steal bases because he has speed,” Randolph said. “He’s going to learn how to understand what they’re trying to do to him from an offensive standpoint. And he’s adaptable. I think he’s going to learn how to do that. Now how quickly that comes, that’s the key.”

Randolph has spent time with Lombard as a special guest instructor at spring training. They would sit together in the dugout during games and Randolph would ask questions.

“ ‘How would you make that play?’ ” Randolph said. “I love the players to talk to me. 'What do you think? How would you have done that differently?’ You can tell he’s very smart. He’s a little shy and I’m a little intimidating maybe.”

After all, he is Willie Randolph. But the former six-time All-Star second baseman saw the quiet side as respect, “like ‘let me listen.’ ”

And he has noticed something else about Lombard.

“There’s an ‘it’ to him,” Randolph said. “So I’m excited for him because I think he has ‘it’ at a young age. I think he has something there that’s going to help him adjust because he’s going to have to adjust . . .  But I love him.”

Another former Yankees shortstop also has been serving as a special guest instructor at spring training. He saw the growth in Lombard over the last few years down in Tampa.

“From Triple-A to the big leagues, the game’s going to get a little faster, but it looks like he’s going to be OK,” Bucky Dent said. “Offensively, it will take him a little time to see how they’re pitching him and stuff. But it looks like he has a pretty good swing. He’s got some power.

“He’s got all the ability . . . He’s going to be a real good player.”

A future big star in New York?

“You know what? I think he has the chance,” Dent said. “ . . . Let him play. Let him grow.”

Family matters

Lombard grew up around the game. His dad played six seasons in the big leagues before coaching with the Dodgers and the Tigers; he’s now Detroit’s bench coach. So that certainly has helped George Jr. when it comes to a comfort level in the clubhouse.

But he’s still young and there’s a hot glare in this area, especially when the expectations are running so high for the 2023 first-round pick. Lombard has been unfazed, though.

“I think it comes with his family and lineage, with a great dad, a great mom,” first-time Old-Timer Todd Frazier said. “Just a sports background and the pressures that come with it, I think he learned that at a young age, and it makes it real easy for him to play this game.”

Lombard seems so composed.

“Not only composed but humble,” Cone said. “That’s a great combination for a young player to endear himself to everyone.”

When Roy White was a young Yankee, Mickey Mantle and Roger Maris were his teammates. White first came up in 1965. The leftfielder played 15 seasons in pinstripes. Now he’s 82, and he enjoyed the view of Lombard’s debut against the Cardinals.

“I was very impressed with his poise and how he handled himself in the field that night,” White said. “Because if you’re really under stress, it’s going to happen defensively, probably on an easy play. That’s the one that you’re going to probably boot if you get a little too nervous out there. And he didn’t show any of that.”

Joe Torre knows George Lombard Sr. and how excited he was about George Jr. “getting drafted by the Yankees.” The Hall of Fame manager knows something else.

“As Sinatra said, ‘You make it here, you can make it anywhere,’ ” Torre said.

Lombard is off to a good start. He was grinding out very good at-bats against Atlanta, going 2-for 3 with a fifth-inning walk against the very tough Chris Sale. That free pass required Lombard to make consecutive ABS challenges to change strike three calls; he was right each time.

His homer to start the seventh went sailing the other way, landing in the right-field seats for a 4-2 lead. He added a single in the eighth.

At previous levels, he had struggled before adjusting.

“The more I’ve done it over the years, the more comfortable I’ve been with dealing with that and dealing with the adjustment period,” Lombard said.

On this day, he even got to meet up with a few of the Old-Timers, too.

“It’s obviously really cool — legends,” Lombard said. “Getting to spend some time with them is always awesome.”

Perhaps one day George Lombard Jr. will join the legends club.
