French Open title hopefuls Novak Djokovic and Francesca Schiavone gave the Roland Garros crowd a glimpse only of their abilities on Monday as they sped into the second round on a hot, sunny day.
Second seed Djokovic extended his winning streak to 40 matches with a 6-2, 6-1, 6-3 dismissal of Dutchman Thiemo de Bakker while defending champion Schiavone raced past American Melanie Oudin 6-2, 6-0.
Djokovic's path ahead became less challenging after possible quarterfinal opponent Tomas Berdych became the first big casualty in the men's singles.
The Czech sixth seed, a semifinalist last year, slumped to a shock 3-6, 3-6, 6-2, 6-2, 9-7 defeat against French qualifier Stephane Robert.
Third seed Roger Federer was given a decent workout before seeing off Spaniard Feliciano Lopez 6-3, 6-4, 7-6.
