Iga Swiatek took just 40 minutes to register a crushing 6-0 6-0 win over Anastasia Potapova and reach the French Open quarter-finals.
The two-time defending champion showed why she is the overwhelming favourite for the title with a relentlessly dominant performance.
Top seed Swiatek won 48 points - against 10 won by world number 41 Potapova - and did not face a single break point.
"It went pretty quickly," Swiatek said.
"I was really focused and in the zone. I wasn't looking at the score, so I continued working on my game."
She will face either Wimbledon champion Marketa Vondrousova or Serb qualifier Olga Danilovic next.
