NEW YORK — At some point, of course, Rafael Nadal, Roger Federer and Novak Djokovic will stop winning Grand Slam titles, someone younger will emerge and a shift at the top of tennis will happen.

Just not yet.

And while so much attention in the sport has been focused recently on trying to figure out who will break up the dominance of Nadal, Federer and Djokovic, it might just be more fun to contemplate — from now until the Australian Open in January, at least — how that trio’s competition for the most major championships will end up when they’ve all walked away from the game.

After eventually emerging with a 7-5, 6-3, 5-7, 4-6, 6-4 victory over Daniil Medvedev in a memorable seesaw of a U.S. Open final Sunday, Nadal insisted that he wants the record by the time he’s done but that it’s not all that matters to him or how he’ll define his own happiness.

That’s fine, of course. To each his own. But the rest of us can — and should — track it and care.

“He’s in a better position today,” one of Nadal’s coaches, Francisco Roig, said after his guy edged Medvedev in a 4-hour, 50-minute epic. “But all of them are still winning tournaments. It’s a long way, but he’s in the best position.”

Here’s the current count: Federer 20, Nadal 19, Djokovic 16.

In 2019, Djokovic and Nadal won two majors apiece, drawing closer to Federer, whose most recent Slam trophy came at the 2018 Australian Open.

Each has a career Grand Slam, too.

Federer owns eight titles from Wimbledon, six from the Australian Open, five from the U.S. Open, one from the French Open.

Nadal has 12 from the French Open, four from the U.S. Open, two from Wimbledon, one from the Australian Open.

Djokovic has seven from the Australian Open, five from Wimbledon, three from the U.S. Open, one from the French Open.

The other relevant numbers are their ages. Federer is 38, Nadal 33, Djokovic 32.

Nadal hasn’t been this close in the title standings since the score was Federer 1, Nadal 0 after Wimbledon in 2003. By the time Nadal picked up his first major, at the 2005 French Open, he trailed 4-0.

For so many years, so many folks were prepared to proclaim Federer as the greatest of all time based largely on his accumulation of majors and a subjective assessment of supposed aesthetics. Others point out that Nadal’s edge in their head-to-head series, which currently stands at 24-16, should give him the nod. Djokovic, meanwhile, elbowed his way into the discussion, too, because he’s the only one to win four majors in a row, leads both of the others head to head (26-22 over Federer, 28-26 over Nadal) and broke up their hold on the No. 1 ranking.

What’s most impressive, really, is how the trio has ruled the sport for about 15 years.

“The three of us are doing things that never were done in the history of tennis,” Nadal said. “I take pride in being part of this fight.”

They won 51 of the last 59 Grand Slam titles, including the past 12, and there hasn’t been a first-time male champion at a major since 2014.

Here’s how different things are in the women’s game. Bianca Andreescu’s 6-3, 7-5 win against Serena Williams on Saturday made the 19-year-old Canadian the seventh first-time female champion in the past 11 majors.

To put it another way: Andreescu gave the women a Grand Slam champion born in the 2000s before the men have had one who was born in the 1990s.

Some took it as a sign that change was afoot when Nadal was the only member of the trio to get to the semifinals at the U.S. Open. Djokovic, the defending champion and No. 1 seed, stopped because of pain in his left shoulder while way behind in his fourth-round match. Federer, dealing with a bad back, bowed out in five sets in the quarterfinals.

Two 23-year-olds reached the semifinals, Medvedev and Matteo Berrettini, so maybe this was the time for a younger man to hold a trophy.

Instead, Nadal became the first man in the professional era to win five majors after turning 30.

“I can say that I’m sure all of us, we’re fighting our best to try to make this transition. It’s really tough, because these guys, they are playing good tennis. I don’t know what else to say. They are just playing amazing tennis,” Medvedev said. “It’s really tough to beat them, even to get a set from them. Even every game, to win, is tough. We’re just doing our best job to try to make it happen sometimes.”
