Bhupathi and Vizner, seeded eighth in the event, beat Paes and Damm 7-6 (7) 2-6 10-8.

Paes and Damm were playing their first match in the hard court tournament after getting a bye in the first round and a walkover in the second.

Very little separated the two pairs in the thrilling opening set in which both teams held serve. Paes and Damm did well to save as many as seven break points but Bhupathi and Vizner took the set in the tie-breaker.

The fourth seeded Indo-Czech duo, however, stormed back into the match in the second set, breaking their opponents twice in the process.

But Bhupathi and Vizner recovered from the jolt and held their nerves to seal the issue in a close super tie-breaker.

The eighth seeds now have a tough match ahead against the American Bryan brothers, who defeated the French pair of Arnaud Clement and Richard Gasquet 6-2 7-6 (3) in their quarterfinal.
