Jannik Sinner has celebrated his imminent takeover as world No 1 with a crushing win over Grigor Dimitrov at the French Open, while defending champion Novak Djokovic bowed out with a knee injury.
There was no drama on the women's side as holder Iga Swiatek continued her quest for a fourth Roland Garros trophy by hitting top gear during a 6-0 6-2 victory over 2019 runner-up Marketa Vondrousova to also reach the semi-finals.
The 23-year-old's 62-minute workout set up a seismic last-four encounter with American Coco Gauff in a repeat of the 2022 final won by the Pole who will look to improve her 10-1 overall record against the third seed.
"Today it was pretty straightforward. I'm happy that I kept my focus. Sometimes I felt the game was pretty intense. Sometimes the intensity went down a bit. I wanted to just play my game no matter what was coming back from Marketa. I felt like I was in the zone today.
"Against Coco it isn't easy. She really likes clay, especially here. I'll just focus on myself and I'll prepare tactically and we'll see."
Gauff earlier fought back to beat fan-favourite Ons Jabeur 4-6 6-2 6-3.
Since Australian Ash Barty's retirement, world No 1 Swiatek, Aryna Sabalenka and Elena Rybakina have won six of the last eight Grand Slam titles to earn the "Big Three" tag.
But 20-year-old Gauff - who won her first Grand Slam title at last year's US Open - has climbed up to third in the rankings, sandwiched between the big-hitting Sabalenka and Rybakina.
Although Gauff had struggled during the claycourt swing as she looked to fine tune her serve, the American has worked on her weaknesses to turn it into a potent weapon. Against Jabeur, she consistently hit 200 km/hr, with one serve clocking 205 km/h - the fastest serve hit by a woman at Roland Garros this year.
Roland Garros was rocked towards the end of Sinner's routine win as organisers announced that Djokovic, 37, had withdrawn from his 2023 final rematch with seventh seed Casper Ruud in the last-eight on Wednesday.
Djokovic needed a superhuman effort and five sets to subdue Argentine Francisco Cerundolo on Monday after being dragged the distance for a second straight contest and the Serb aggravated the injury he had been carrying by slipping on court. MRI results revealed that Djokovic, who played on with pain-killers, had suffered a torn medial meniscus that prompted him to take the decision.
Even as Djokovic arrived at Roland Garros to clean out his locker, Sinner was easing to a 6-2 6-4 7-6(3) win over Dimitrov and the 22-year-old said he had achieved a lifelong dream, even if it was not the way he expected to.
"What can I say? First of all it's every player's dream to be number one. On the other hand, seeing Novak retiring here is, for everyone, disappointing. I wish him a quick recovery," Sinner said.
The Australian Open champion will renew his great rivalry with Carlos Alcaraz in the semi-final, after the two-times Grand Slam champion put on a clinical performance to beat former Roland Garros runner-up Stefanos Tsitsipas 6-3 7-6(3) 6-4.
Alcaraz dropped only three of his first-serve points in the first set and held his nerve through the tiebreak to halt the Greek's mid-match comeback, before delivering one of his superb dropshots on match point.
The Spaniard assured the crowd at Roland Garros that his meeting with Sinner would not disappoint, with the Italian playing at the top of his game.
"It's going to be a really difficult challenge for me. I'm ready to take that challenge," said Alcaraz.
"It is the match that everybody wants to watch and I'm sure that he's going to show his best tennis, myself as well."
The pair are evenly split with their career head-to-head record at 4-4. Alcaraz won their most recent meeting, a semi-final match at Indian Wells this year.
"You have to run like it is a marathon, you know, side-to-side... Everything he does, he does it perfectly," Alcaraz told reporters. "I think it is the hardest thing to face Jannik. At the same time I love that. I love these kind of matches."
