At the Australian Open, top seed Iga Swiatek of Poland lost in the third round to 19-year-old Linda Noskova of the Czech Republic, ranked 50th.
Noskova, the 2021 French Open junior champion, won 3-6, 6-3, 6-4 in Melbourne.
“I felt like I had everything under control until she broke me in the second set,” Swiatek said. Two days ago, I almost lost in the second round.. “Coming here, I just can't play naturally (during competitions). I don't know, my split step was too slow at times. My reactions are a little slow. And a few other things.”
Noskova will take on 19th seed Elina Svitolina of Ukraine in the last 16.

“It was an unbelievable match for me,” Noskova said. “If you're aggressive, you can play with anyone.”
Noskova ended Swiatek's winning streak that started on October 1st at 18. She became the youngest player to beat the world No. 1 in a Grand Slam since Nicole Vaidisova defeated Amelie Mauresmo at the 2006 French Open.
Swiatek has been a dominant player in the world since he first became world No. 1 in March 2022, winning the French Open three times and the US Open once. Her best Australian Open result was reaching the semi-finals in 2022.
Swiatek was the last top 10 player in the top half of the women's draw.
Victoria Azarenka, the 2012 and 2013 Australian Open champion from Belarus, is the most accomplished player remaining in the top half.
