No. 7 seeds Lukas Dlouhy and Leander Paes (pictured) needed only 69 minutes to reach the US Open quarterfinals with a 6-3, 6-3 victory over Rik De Voest and Ashley Fisher on Sunday.

Dlouhy and Paes, who first teamed up at Roland Garros in May when they reached the third round (l. to eventual champs Cuevas/Horna), improved their match record to 15-5 together. They also were finalists in Halle, semifinalists at Wimbledon and ATP Masters Series Toronto and quarterfinalists at ATP Masters Series Cincinnati. Their last three losses have come to World No. 1 Daniel Nestor and Nenad Zimonjic. They will meet again if Nestor/Zimonjic win their third round match on Monday (vs. Lindstedt/Nieminen).

Dlouhy and Paes converted three of six break points while saving two of three break points on their serve. In their previous two rounds, they prevailed in three sets.

In the only other third round match Sunday, unseeded Germans Christopher Kas and Philipp Petzschner surprised Czech Republic No. 11 seeds Martin Damm and Pavel Vizner 6-3, 7-6(6).

Kas and Petzschner, who are playing in only their third tournament together this season (ATP World Team Championship, Halle), advanced to their first Grand Slam quarterfinal as a duo. This is only their fourth Grand Slam tournament together (4-3 record).

Kas and Petzschner, who upset No. 5 seeds Jonas Bjorkman and Kevin Ullyett in the second round, won 65% of second serve points to the Czech's 39%. They converted two of eight break points while only losing serve once.

The Germans will take on the winner of Michal Mertinak/Lovro Zovko and No. 2 seeds Bob and Mike Bryan in the quarterfinals.
