Frances Tiafoe ended Rafael Nadal’s 22-match winning streak at Grand Slam tournaments by beating the 22-time major champion 6-4, 4-6, 6-4, 6-3 in the U.S. Open’s fourth round Monday.

Tiafoe is a 24-year-old from Maryland who is seeded 22nd at Flushing Meadows and reached the second major quarterfinal of his career.

He is the youngest American man to get that far at the U.S. Open since Andy Roddick in 2006, but this was not a case of a one-sided crowd backing one of its own. Nadal is about as popular as can be in tennis and heard plenty of support in Arthur Ashe Stadium as the volume rose after the retractable roof was shut during the fourth set.

“I don’t even know what to say right now. I’m beyond happy. I can’t believe it,” said Tiafoe, who faces No. 9 seed Andrey Rublev next. “He’s one of the greatest of all time. I played unbelievable tennis today, but I don’t even know what happened.”

Here’s what happened: Tiafoe served better than No. 2 seed Nadal. More surprisingly, he returned better, too. And he kept his cool, remained in the moment and never let the stakes or the opponent get to him. The 36-year-old from Spain had won both of their previous matches, and every set they played, too.

“Well, the difference is easy: I played a bad match, and he played a good match,” Nadal said. “At the end that’s it.”

This surprise came a day after one of Tiafoe’s pals, Nick Kyrgios, eliminated the No. 1 seed and defending champion Daniil Medvedev. That makes this the first U.S. Open without either of the top two seeded men reaching the quarterfinals since 2000, when No. 1 Andre Agassi exited in the second round and No. 2 Gustavo Kuerten in the first.

That was before Nadal, Novak Djokovic, who has 21 Grand Slam titles, and Roger Federer, who has 20, began dominating men’s tennis. Djokovic, who is 35, did not enter this U.S. Open because is not vaccinated against COVID-19 and was not allowed to enter the United States; Federer, 41, has undergone a series of operations on his right knee and has not played since Wimbledon last year.

Now come the inevitable questions about whether their era of excellence is wrapping up.

“It signifies that the years go on,” Nadal said. “It’s the natural cycle of life.”

Either Tiafoe or Rublev will advance to a first major semifinal. Rublev, who is 0-5 in Slam quarterfinals, beat No. 7 Cam Norrie 6-4, 6-4, 6-4 earlier Monday.

The No. 1 woman, Iga Swiatek, covered her head with a white towel during one changeover after falling behind by a set and a break in her fourth-round match. She kept making mistakes, then rolling her eyes or glaring in the direction of her guest box.

Eventually, Swiatek got her strokes straightened out and moved into her first quarterfinal at Flushing Meadows by coming back to beat Jule Niemeier 2-6, 6-4, 6-0.

“I’m just proud,” Swiatek said, “that I didn’t lose hope.”

The 21-year-old from Poland will face another first-time U.S. Open quarterfinalist next. That’s No. 8 seed Jessica Pegula, the highest-ranked American woman, who advanced with a 6-3, 6-2 victory over two-time Wimbledon winner Petra Kvitova.

Nadal won the Australian Open in January and the French Open in June. Then he made it to the semifinals at Wimbledon in July before withdrawing from that tournament because of a torn abdominal muscle; that does not go into the books as a loss, because he pulled out before the match.

Nadal competed only once in the 1½ months between leaving the All England Club and arriving in New York while recovering from that injury. His play has not been up to his usual standards at the U.S. Open, which he has won four times.

The match ended when one last backhand by Nadal found the net. Tiafoe put his hands on his headm then he sat in his sideline chair with his face buried in a towel.

“When I first came on the scene, a lot of people had limitations on what I would do. … I wasn’t ‘ready for it mentally.’ I wasn’t ‘mature,’” Tiafoe said. But these days, he added, “I’m able to just do me and do it my way and enjoy the game I love.”

This represents the latest significant step forward for Tiafoe, whose only previous trip to a Grand Slam quarterfinal came at the 2019 Australian Open — and ended with a loss to Nadal.

Tiafoe thanked a long list of folks who were in the stands, including his parents — they emigrated from Sierra Leone in West Africa and his dad worked as a maintenance man at a tennis facility near the U.S. capital — his girlfriend and Washington Wizards All-Star guard Bradley Beal.

“To have them see what I did today means more than anything,” Tiafoe said. “Today’s an unbelievable day and I’m going to soak this one in, for sure.”
