Defending champion Iga Swiatek is the French Open favorite after the world’s top three players were all out of the draw before the third round, none having lost a completed match.
Ash Barty, the top seed and 2019 champion, retired during her second-round match with a hip injury.
No. 2 seed Naomi Osaka, who has never made it past the third round in Paris, withdrew after her first-round win, citing mental health struggles.
Simona Halep, the world No. 3, withdrew before the tournament with a calf tear.
Swiatek won the title last autumn as the world’s 54th-ranked player in the best combination of unheralded Grand Slam dominance in more than 40 years.
