Karolina Pliskova overcame a spirited challenge from World No. 172 Mayar Sherif, the first Egyptian woman to play the main draw at a Grand Slam, to reach the French Open second round. Second seed Pliskova, a semi-finalist in 2017, squandered eight set points in Tuesday's opening set as Sherif took a shock lead but the Czech recovered to progress 6-7 (9/11), 6-2, 6-4.

Pliskova will face 2017 champion Jelena Ostapenko for a place in the Last 32. Ostapenko said she believes she can return to the world's top 10 with a little more consistency in her game after securing her first French Open victory since lifting the trophy in 2017. The Latvian, 23, blasted 46 winners en route to a 6-2, 6-1 defeat of Madison Brengle.
