Maria Sakkari eased past Sofia Kenin with a relentless 6-1 6-3 win in the fourth round of the French Open on Monday afternoon in Paris.
The 17th seed Greek kicked off the upset in the first set when she broke her American rival early in the match, and did not look back, securing a 6-1 advantage on Court Suzanne Lenglen.
Neither Sakkari nor Kenin succeeded with their first serve to any great extent, but the 25-year-old started to improve a little in the second set while her opponent continued to struggle, and while her first serve percentage continued to hover around just 50%, she won points on more than 80% of them.
Kenin failed to offer much resistance in her service games, and the 22-year-old was broken consistently in both sets.
With the momentum with Sakkari it took little effort for her to secure another set, with Kenin only offering momentary late resistance, and sail through to the quarter-finals at Roland-Garros.
