TOP seed Serena Williams made swift progress into round two of the French Open on day three but last year’s semi-finalist Eugenie Bouchard was beaten.
Williams, the champion at Roland Garros in 2002 and 2013, beat Czech Andrea Hlavackova 6-2, 6-3.
But Canadian sixth seed Bouchard lost 6-4, 6-4 to France’s Kristina Mladenovic, the world number 44, her eighth defeat in nine matches.
Men’s title favourites Novak Djokovic and Rafael Nadal won in straight sets.
Seventh seed David Ferrer saw off Lukas Lacko 6-1, 6-3, 6-1 to record the 300th clay-court win of his career, while women’s fourth seed Petra Kvitova survived a scare before beating New Zealand’s Marina Erakovic 6-4, 3-6, 6-4.
