MELBOURNE – Top seed Iga Swiatek and a tearful Coco Gauff both crashed out in straight sets in the Last 16 on Sunday in yet more shocks at the Australian Open.
Swiatek’s defeat to Elena Rybakina makes it the first Grand Slam in the Open era – since 1968 – to lose the top two seeds in the men’s and women’s draws before the quarterfinals.
Wimbledon champion Rybakina swept past the 2022 French and US Open winner from Poland 6-4, 6-4 in 1hr 29min at a stunned Rod Laver Arena in Melbourne.
Moscow-born Kazakh Rybakina moves on to a last-eight encounter with Jelena Ostapenko.
The Latvian 17th seed provided the second upset of a crazy few minutes by knocking out seventh seed Gauff 7-5, 6-3 on neighboring Margaret Court Arena.
The 18-year-old Gauff broke down in tears during an emotional post-match press conference.
World No. 1 and hot favorite Swiatek admitted that the 22nd-seeded Rybakina deserved to win.
“I felt the pressure,” Swiatek, 21, said. “I felt that I didn’t want to lose instead of wanting to win.”
Meanwhile, third seed Stefanos Tsitsipas survived a huge scare Sunday to battle into a third consecutive Australian Open quarterfinal and a showdown with Czech surprise package Jiri Lehecka.
The Greek star extended his win streak this year to eight matches with a gutsy 6-4, 6-4, 3-6, 4-6, 6-3 triumph over dangerous Italian 15th seed Jannik Sinner on Rod
Laver Arena as the clock ticked over four hours.
Victory teed him up with a clash against Lehecka for a place in the semis after the Czech 21-year-old stunned sixth seed Felix Auger-Aliassime 4-6, 6-3, 7-6 (7/2), 7-6 (7/3).
Swiatek, who dominated women’s tennis last year and is already a three-time major champion, added: “I felt today that I don’t have that much left to fight even more.
“I felt like I took a step back in terms of how I approach these tournaments, and I maybe wanted it a little bit too hard.
“So I’m going to try to chill out a little bit more.”
Swiatek follows second seed Ons Jabeur out the Melbourne exit door, the Tunisian having gone out in the second round in another surprise.
The American Gauff had been favorite to defeat Ostapenko, the 2017 French Open winner.
But the 25-year-old Ostapenko was always in control to ensure that Gauff must wait at least a bit longer for a first major title.
“I knew she’s such a great player, super young and she’s playing really well, but I really had nothing to lose,” said Ostapenko.
“I just went there and tried to show my best and try to fight for every point, and to make it hard for her, and I’m really happy with the way I played.”
Ostapenko, whose last Grand Slam quarter-final came at Wimbledon in 2018, has endured some tough injury-hit years since and had never before beaten a player ranked in the top 10 at the Australian Open.
“I was trying to stay positive all the time,” said Ostapenko. “And I knew I have to play aggressive, even if I miss some balls.”
Third seed Jessica Pegula and in-form fifth seed Aryna Sabalenka now look the women to beat, as both chase a first Grand Slam crown.
American Pegula faces 20th seed Barbora Krejcikova later Sunday in the fourth round.
