LONDON — Jannik Sinner felt ill. He was dizzy. He had slept badly the night before. The number one seed at Wimbledon, who has recently become number one in the world rankings, didn’t really want to give up his quarterfinal match against Daniil Medvedev, but things weren’t looking good.

Sinner was treated by a trainer and left the court during the third set on Tuesday. He briefly regained momentum after that before faltering again in the home stretch and eventually losing to a more aggressive than usual Daniil Medvedev 6-7 (7), 6-4, 7-6 (4), 2-6, 6-3.

“I was struggling physically,” said Sinner, who had won his last five matches against Medvedev, including a five-set match in the Australian Open final in January. “It was not an easy moment. I tried to fight with what I had today.”

It wasn’t enough.

Not against the cunning Medvedev, the 2021 US Open winner, who will now face Carlos Alcaraz in the semifinals of the All England Club for the second time in a row.

“It was a somewhat up-and-down game from both sides,” Medvedev said.

Alcaraz, the defending champion and No. 3 seed, took some time to get going in his quarterfinal, but once he did, he was unstoppable in a 5-7, 6-4, 6-2, 6-2 victory over No. 12 Tommy Paul on Court No. 1.

“We’re just trying to find solutions,” said Alcaraz, who won a French Open title last month and is now aiming for his fourth Grand Slam title. “For me, of course, it will be very difficult to play my best tennis in every match.”

On Centre Court, it was not immediately clear what was wrong with Sinner. He leaned back in his chair on the sideline, rested his head in one hand and had his pulse checked before heading to the locker room. At a later change of ends, Sinner placed a towel over his head.

Although he regained his usual verve, particularly with his powerful forehand, and took the match to a fifth set – the 36th in those two weeks and the most at a Grand Slam tournament in the Open Era, which dates back to 1968 – Sinner could not get over the finish line.

Although he won more points (164-160), accumulated more winners (61-56), made fewer unforced errors (49-45), hit more aces (17-15) and finished with far fewer double faults (11-4).

“That’s hard to swallow,” Sinner said.

Medvedev, a 28-year-old Russian, started playing closer to the baseline than he often does. He found the space to hit more winners, hitting 13 in the final set alone, breaking in the fifth set to make it 3-1 and heading back to the semifinals.

“Today,” said Medvedev, “a lot of tactical things worked well.”

After eliminating 22-year-old Sinner, Medvedev now faces 21-year-old Alcaraz – two consecutive friendly matches against the two new young stars of men’s tennis.

Against Paul, Alcaraz raised his level after a mediocre first set and built up a 26-12 lead in the winners in the last three sets.

“When he starts to build energy and momentum … it feels a little different than most of the other guys,” Paul said. “He can really play some incredible tennis.”

In the women’s quarterfinals, Donna Vekic reached the last four of a major for the first time in her 43rd Grand Slam tournament by defeating qualifier Lulu Sun 5-7, 6-4, 6-1. French Open runner-up Jasmine Paolini eliminated No. 19 seed Emma Navarro 6-2, 6-1 in less than an hour.

Navarro defeated four-time major winner Naomi Osaka and reigning US Open champion Coco Gauff at the start of the tournament.

“I know this is not the last time I’ll be in the quarterfinals of a Grand Slam,” Navarro said. “I know I’ll be back.”

Vekic, a 28-year-old Croatian, had considered giving up the sport several times – most recently shortly before the start of the Roland Garros matches in May.

“I had no energy, no motivation to keep training, to keep going, because I felt like I had given everything for tennis in the last few months and had not achieved the results I expected,” Vekic said.

“Now I’m in the semifinals,” said Vekic. “Not only in tennis, but also in life, things can change pretty quickly.”

Sinner was a semifinalist at Wimbledon a year ago and was on a nine-match winning streak until Tuesday, including a grass-court title in Halle, Germany, last month. He rose to No. 1 in the ATP rankings on June 10, replacing Novak Djokovic, after reaching the semifinals at the French Open.

His exit follows that of the number one seed, Iga Swiatek, in the third round. It is the first time since 2018 that both the top female and male players have been eliminated from Wimbledon before the semifinals. That year, Roger Federer lost in the quarterfinals and Simona Halep in the third round.

Medvedev won the first two sets against Sinner in Australia. But Sinner fought back and won his first Grand Slam title.

The result reduced Medvedev’s career record in major finals to 1-5, and he now has just one win in his seventh such appearance.

“Hopefully I can win a few more Grand Slams,” said Medvedev. “I believe in myself. I believe in my tennis.”
