Elena Rybakina upset Serena Williams 6-3, 7-5 in the fourth round of the French Open on Sunday.

Williams never quite got into her rhythm, committing 19 unforced errors in the two-set match. Rybakina capitalized on the former French Open champion’s shaky services game, breaking Williams five times.

Rybakina now advances to her first-ever Grand Slam quarterfinal. The No. 21 seed will face No. 31 seed Anastasia Pavlyuchenkova, fresh off her own three-set win over Victoria Azarenka.

Williams’ quest for her 24th Grand Slam title will have to wait for Wimbledon, which is set to begin on June 28.
