MELBOURNE: Stefanos Tsitsipas battled into the Australian Open’s last eight on Sunday but women’s top seed Iga Swiatek and a tearful Coco Gauff became the latest big-name victims.
Swiatek’s defeat to Elena Rybakina made it the first Grand Slam since the Open era began in 1968 to lose the top two seeds in both the men’s and women’s draws before the quarter-finals.
That left Greece’s Tsitsipas as the highest remaining men’s seed at three, and he avoided the fate of Rafael Nadal and Casper Ruud with a dogged victory over Jannik Sinner.
Tsitsipas, who is pursuing a first major crown, defeated the Italian 15th seed 6-4, 6-4, 3-6, 4-6, 6-3 to set up a quarter-final with the unseeded Jiri Lehecka.
“It was a long match, I felt like I spent an entire century on this court playing tennis,” said the 24-year-old Tsitsipas, who has seen the draw open up for him with six of the top 10 seeds out.
“What a great night. That was superb, ‘a ripper’ as they say here.” Czech world number 71 Lehecka defeated sixth seed Felix Auger-Aliassime in four sets in yet another surprise result.
The 21-year-old Lehecka was knocked out in the first round at the four majors last year but was too hot for the Canadian, winning 4-6, 6-3, 7-6 (7/2), 7-6 (7/3).
“After losing in the first round last year, if someone had told me before the tournament that I would be playing like this, I wouldn’t have believed them,” said Lehecka.
“I’m super happy and excited.”
Giant-killer Sebastian Korda surged into a maiden Grand Slam quarter-final and faces 18th-seeded Karen Khachanov of Russia.
The American 29th seed came through a rollercoaster 10-point deciding tiebreak to beat 10th seed Hubert Hurkacz 3-6, 6-3, 6-2, 1-6, 7-6 (10/7).
Korda, whose father Petr won the title in 1998, produced one of the performances of his career to upset two-time Australian Open finalist Daniil Medvedev in the third round.
