It was an anticlimax Middle Sunday at Roland Garros. Mihaela Buzarnescu, the conqueror of fourth seed Elina Svitolina, and Anett Kontaveit, who eliminated eighth seed Petra Kvitova, both suffered quick losses in the fourth round, while the thrilling night encounter between Daria Kasatkina and Caroline Wozniacki had to be suspended in the second set due to darkness.
Winning 82% of points on first serve, seed No.13 Madison Keys largely eased past the 31st-seeded Buzarnescu 6-1 6-4, only having some trouble at the conclusion, missing two match points at 5-2 40-15, allowing the Romanian to win two more games before losing the match in one hour and five minutes.
