A dominant Karen Khachanov won the first 14 games before surging into his maiden Australian Open quarter-final on Sunday in a straight sets romp over Japan’s outclassed Yoshihito Nishioka.
The Russian 18th seed swept past his racquet-smashing opponent 6-0, 6-0, 7-6 (7/4) on John Cain Arena.
Nishioka, seeded 31, was so out of touch in the opening two sets that he won just 13 points.
In set two, he managed only two points across six games in an embarrassing annihilation.
