Elina Svitolina lost 6-3, 6-2 on Saturday to leave the French Open women’s draw decimated with four of the five leading seeds all gone.
The three-time quarter-finalist from Ukraine lost to Czech Barbora Krejcikova, who lifted her first career singles title last week in the Strasbourg run-up tournament.
The 33rd-ranked Czech has been dominating in doubles, picking up the French and Wimbledon titles in 2018 and finishing runner-up at the Australian Open with partner Katerina Siniakova.
With Svitolina out, only three of the Top 10 seeds remain: 2020 finalist Sonia Kenin, holder Iga Swiatak and Serena Williams.
Krajcikova’s win included a mega-game lasting 21 minutes at 4-3 in the first set, which resulted in a break of Svitolina.
“I’m so super happy I didn’t really believe it,” the winner said. “I was able to play tennis and the game plan was working.
“My shots were amazing, this is my best match so far.”
Krajcikova will play for the quarter-finals against 2017 US Open winner Sloane Stephens after the unseeded American defeated 19th-ranked Czech Karolina Muchova 6-3, 7-5.
