World No. 1 and defending champion Jannik Sinner battled past Holger Rune and injury concerns to reach the quarterfinals of men’s singles at the Australian Open 2025. Sinner wrapped up the opening set 6-3 after just 33 minutes but struggled physically in the second set and took a medical time-out. Sinner, however, won the third and the fourth sets to march into the quarter-final.
“Today was a strange morning, I didn’t even warm up … I knew in my mind that I would struggle today,” Sinner said. “It was for sure, very, very tough, I knew he had some very long matches before this one so I tried to stay there mentally. I just tried to stay connected with my service game and then on the returning game, just trying to see what happens.”

Sinner had to rush to the locker room before the third set, when he asked for a doctor and exited the court for a medical timeout. Rune, eyeing to become the first Danish man to reach the Australian Open quarter-finals, failed to capitalise on his physical advantage over his Italian opponent. Sinner then broke for 5-3 and served out the third set.
Rune also took a locker room break and then the fourth-round clash was delayed further due to a malfunction with the net. The officials took 20 minutes to fix the net, during which both the players were forced off the court. Sinner then returned to capitalise on Rune’s errors and register his 18th successive tour-level win.
Rune’s 54th unforced error ensured Sinner’s spot in his 10th Grand Slam quarter-final. With this win, Sinner equalled Nicky Pietrangel’s Italian record in Grand Slams. The World No.1 Italian star will next take on either Alex de Minaur or Alex Michelsen. Sinner has defeated both De Minaur and Michelsen in the last 11 encounters.
