Elina Svitolina became the seventh top-10 seed to be knocked out in the French Open's opening week as she fell in the third round to Barbora Krejcikova.
The Ukrainian follows Ashleigh Barty, Naomi Osaka, Karolina Pliskova, Aryna Sabalenka, Belinda Bencic and Bianca Andreescu out of Roland Garros.
Krejcikova next faces Sloane Stephens, who beat 18th seed Karolina Muchova.
Stephens, the 2017 US Open champion and 2018 runner-up at Roland Garros, triumphed 6-3 7-5 against the out-of-sorts Czech.
Both players struggled for accuracy throughout, Stephens hitting 25 unforced errors and Muchova 32, but the 28-year-old American broke serve early in the first set and, crucially, at 5-5 in the second, to progress.
