The American needed six set points to close out the opening frame. The decisive second set was even more tightly contested.

Bouzkova fought off two match points to force a tie-break, and only there did Pegula really manage to get on top. The American raced into a 5-0 lead, and the writing was belatedly on the wall. Top seed Iga Swiatek swept into the fourth round, beating No.

28 seed Bernarda Pera 6-3 6-2. The world No. 1 improved her career record on clay to an all-time leading 88.2%, ahead of the iconic Serena Williams' career average of 88%.

Swiatek defended her Porsche Tennis Grand Prix title in Stuttgart last weekend, beating world No. 2 Aryna Sabalenka in straight sets, and is in a serious vein of form as Roland-Garros approaches. She will face the winner of Qinwen Zheng v Ekaterina Alexandrova.

No. 8 seed Daria Kasatkina beat Lesia Tsurenko 6-4 6-2 to move to the round of 16. Kasatkina will face Veronika Kudermetova in her next match.
