World number four Elena Rybakina of Kazakhstan sent out a warning to her fellow title contenders as she eased to a 6-4 6-3 victory over Ukraine's Elena Svitolina to reach her second French Open quarter-final.
After a sluggish start with both players dropping serve, Russian-born Rybakina raised her level and cruised through the first set.
In the second set, the 29-year-old Svitolina was no match again for Rybakina as the 19th-ranked Ukrainian showed signs of fatigue from the start and lacked precision under the long-awaited sun after a wet first week on the Paris red clay.
The Kazakh said she would need to be more consistent when she plays 15th-ranked Italian Jasmine Paolini who has reached the last eight for the first time after beating Elina Avanesyan 4-6 6-0 6-1.
"It's all about focus now, the matches are getting tougher, the opening also, so I think it's a lot about the consistency, not having so many ups and downs," she added.
Rybakina withdrew from the French Open last year before her third-round match because of illness.
This season, after winning titles in Brisbane, Abu Dhabi and Stuttgart, Rybakina pulled out of the Italian Open due to health issues.
She is the only player to beat Iga Swiatek on clay this year, defeating the world number one and three-times French Open champion on her way to the Stuttgart title in April.
