The French Open fourth round starts on Sunday with women's top seed Aryna Sabalenka and men's defending champion Carlos Alcaraz both facing American opponents, while Iga Swiatek continues her quest for a fourth straight women's singles title.

Carlos Alcaraz stumbled his way into the last 16 of the 2025 French Open on Friday with a 6-1, 6-3, 4-6, 6-4 win over Bosnian world number 69 Damir Dzumhur. Second seed Alcaraz broke twice in each of the first two sets and seemed to be cruising but a dogged Dzumhur refused to roll over and pinched the third set.
