World number two Karolina Pliskova bombed out to Anastasia Pavlyuchenkova Saturday as the shocks kept rolling in the Australian Open third round.
A day after Serena Williams and defending champion Naomi Osaka both exited, Russia's Pavlyuchenkova won 7-6 (7/4), 7-6 (7/3) for her first victory over the Czech second seed.
The result means that two of the top three seeds are now out of the women's draw, after third-ranked Osaka fell to 15-year-old American Coco Gauff on Friday.
Williams, the seven-time Melbourne champion who was seeking a record-equalling 24th Grand Slam title, was stunned by China's Wang Qiang.
"I don't know what to say, of course I'm really happy but I won't really realise that until later," said Pavlyuchenkova, a quarter-finalist last year and in 2017.
"It was a lot of fun and I actually really enjoyed it."
"I love the heat, even though everyone says you're from Russia and love cold weather, I don't, I hate it!"
