Indian Davis Cupper Rohan Bopanna and his Pakistani partner Aisam-ul-Haq-Qureshi crashed out of the $ 508,000 Legg Mason Tennis Classic tournament after suffering a sets first round defeat in Washington.

The unseeded Indo-Pak pair lost 4-6, 4-6 to third seeded duo of Rik De Voest of South Africa [Images] and Ashley Fisher of Australia [Images] in a little over one-hour contest of the hard court event.

The Indo-Pak combine broke their opponents once but dropped their serve twice to surrender the first set. Though they managed to save two breakpoints.

It was same story in the second set as they won their only breakpoint but lost two games on their serve to hand the match to the rivals.

In singles, qualifier Somdev Devvarman beat American wild card Taylor Dent 7-6 (3), 2-6, 6-1 to advance to the second round where he meets another American in qualifier Robert Kendrick, later on Thursday.
