Leander Paes [Images] is all set to clash Mahesh Bhupathi [Images] with former doubles partner in the quarter-finals of the Rogers Cup without playing a single match in the event.

Paes and his Czech partner Martin Damm, who were given a first-round bye, earned a walkover against Canadian wildcards Frank Dancevic [Images] and Frederic Niemeyer in the second round.

Eighth seeds Bhupathi and Pavel Vizner had beaten Fernando Gonzalez and Ivan Ljubicic 6-4, 6-2 in the second round.

The world number one team of Mike and Bob Bryan vanquished their singles counterpart, Roger Federer [Images], in an exciting second round contest.

Federer, teaming up with fellow Swiss Yves Allegro went down 7-6(7), 6-7(8), 10-7 to the Americans.

Federer and Allegro won two more points than the top-seeded tandem and defending doubles champions during the 1 hour, 38 minute match, but still fell short of victory.

The Bryans have yet to be defeated during the 2007 US Open Series and now boast a nine-match winning streak. They won the Los Angeles and Washington titles in their last two tournament appearances, taking their season trophy count up to a circuit-leading eight titles.
