The No. 3 seed improved to 6-0 against the Greek following Tuesday’s 6-3, 7-6 (3), 6-4 victory.
Earlier, Sinner dashed Grigor Dimitrov’s bid with a 6-2, 6-4, 7-6 (3) victory. With Novak Djokovic’s withdrawal ahead of his quarterfinal due to a knee injury, the Italian will become the first man from his nation to reach No. 1 on the ATP rankings come Monday.
Alcaraz matched Sinner in notching 50 career Grand Slam wins, the first men born in the 2000s to reach that figure. The 21-year-old has now advanced to the semifinals or better at five of the past six majors he’s entered.
Both came to the French capital with questionable statuses: Alcaraz played just one European clay-court tournament after struggling with a right arm injury. Sinner was derailed by a right hip issue that forced him to cut short his Madrid campaign and withdraw from his home event in Rome.
Alcaraz’s budding rivalry with Sinner has seen each competitor win four matches going into their third different Grand Slam meeting. Sinner took their 2022 Wimbledon fourth-round contest before Alcaraz saved match point to claim their 2022 US Open quarterfinal.
Their lone previous clay-court clash also occurred two seasons ago, when Sinner prevailed in the Umag final.
“I think it is the hardest thing to face Jannik,” Alcaraz stated to press. “At the same time, I love that. I love these kind of matches. I love this kind of challenge, to have a really difficult battle against him.”
