Swiatek racks up 31st straight win
World number one Iga Swiatek was the only top 10 women's seed left standing at the French Open on May 28.
Swiatek, the 2020 champion, dropped serve three times against 95th-ranked Danka Kovinic of Montenegro before sealing a 6-3, 7-5 third round victory, her 31st successive win.
"I wanted to play really aggressively but sometimes I felt I was hitting with too much power and it was hard to control," said the 20-year-old Pole.
Swiatek's winning streak is the best since Serena Williams's 34 successive victories in 2013.
She next faces Chinese teenager Zheng Qinwen, who made the last 16 on her debut when French veteran Alize Cornet, playing in her 61st consecutive Grand Slam, retired with a leg injury, trailing 6-0, 3-0.
Having stunned 2018 champion Simona Halep in the second round, Zheng becomes only the fourth Chinese woman to make the fourth round in Paris where compatriot Li Na captured her landmark Slam title in 2011.
"I always knew I had the level to do well, now I just want to keep going," said the 19-year-old Zheng, ranked at 74.
Cornet, the last Frenchwoman in the draw, was booed off by the Court Philippe Chatrier crowd.
"It hurt more than my injury," she said.
Spain's Paula Badosa, who made the quarterfinals in 2021, retired due to a calf injury when she was trailing Russia's Veronika Kudermetova 6-3, 2-1.
Aryna Sabalenka, the seventh seed, slipped to a 4-6, 6-1, 6-0 defeat against Italy's Camila Giorgi.
The exits of Badosa and Sabalenka meant that for the first time in the Open era only one top 10 seed has survived to the fourth round.
