The Bryan brothers stamped their authority without any fuss as they raced away with the first set in just 24 minutes.

Bopanna and Qureshi did put up a fight try in the second set, winning four games, but their American opponents were too experienced and superior in class that there was hardly any threat of an upset.

The winners were dominant in winning points on the first serve and also converted four of the nine breakpoints, that came their way. The Indo-Pak pair on the other hand could win one of five.
