Ukrainian Elina Svitolina: Marta Kostyuk delivered one of the biggest shocks of this year's Roland Garros on Sunday, dismantling four-time champion Iga Swiatek in straight sets to secure her first French Open quarter-final berth.
The Ukrainian, seeded 15th, produced a fearless display to overcome Swiatek 7-5, 6-1, extending her remarkable clay-court winning streak to 16 matches and ending the Pole's hopes of another deep run in Paris.
For Kostyuk, the victory represents another milestone in a season that has transformed her into one of the most dangerous players on clay. Having already captured titles in Rouen and Madrid, she now finds herself among the final eight at Roland Garros for the first time, and just one win away from a maiden Grand Slam semifinal.
