LYON, France — Julien Benneteau upset fifth-seeded Tommy Robredo of Spain 6-2, 6-2 to reach the quarterfinals of the Lyon Grand Prix today.

Robredo faced 13 break points in the match and lost his serve twice in each set to the Frenchman, and he fared little better when returning serve, winning only eight percent of points on his first return.

Benneteau next meets second-seeded Richard Gasquet or Steve Darcis in the quarterfinals. They play Thursday.

Other first-round winners were No. 7 Robin Soderling of Sweden and No. 8 Paul-Henri Mathieu of France. Soderling beat Thierry Ascione of France 6-4, 6-1, while Mathieu defeated Guillermo Canas of Argentina 6-3, 6-4.
