French second seed Jo-Wilfried Tsonga was too good for Argentinian Agustin Calleri, winning their first-round encounter 6-2 7-5.

In the second round, Robin Soderling of Sweden advanced with a comfortable 6-3 6-3 victory over France's Julien Benneteau, while seventh-seeded Frenchman Richard Gasquet overcame American Taylor Dent 7-5 6-4.
