Melbourne, Jan 30 (IANS): Rohan Bopanna and his Ukrainian partner Nadiia Kichenok bowed out in straight sets in the Australian Open quarter-final of the mixed doubles here on Thursday ending India's challenge at the opening Grand Slam of the year.

The Indo-Ukrainian pair lost 0-6, 2-6 to fifth seed Nikola Mektic and Barbora Krejcikova in a lopsided tie.

The Croatian-Czech duo were in the driver's from start to finish as Bopanna and Kichenok could not match their game.

In the second set, Bopanna and Kichenok managed to hold their serve in the first game but once they were broken in the second and the seventh, Mektic and Borbara eased past their rivals and sealed a semi berth.
