Top two seeds, Novak Djokovic and Rafael Nadal, were both untroubled in their openers against Poland's Hubert Hurkacz and Germany's Yannick Hanfmann, respectively, on Court Philippe-Chatrier.

Djokovic cruised through 6-4, 6-2, 6-2 and faces Swiss lucky loser Henri Laaksonen next, while Nadal dropped just six games in his straight-sets rout of Hanfmann. He takes on another qualifier, also German, also named Yannick, in his next match - this time Yannick Maden.

A day after his doubles partner Nicolas Mahut pulled off a sensational comeback from two sets down, fellow Frenchman Pierre-Hugues Herbert fought back from a two-sets-to-one deficit to upset No.12 seed Daniil Medvedev 4-6, 4-6, 6-3, 6-2, 7-5.
