World number 85 Rosol stamped his class as he thrashed 125th ranked Yuki 6-2 6-1 7-5 in one hour and 55 minutes at R K Khanna Tennis stadium here.
The temperature was 31 degree Celsius at the start of the match but neither the conditions nor the game of Yuki proved challenging for the tall Czech, who was ranked as high as 26 last year.
Rosol served extremely well and hit flat and furious groundstrokes, imposing himself on Yuki. The Czech player played smartly and served in the range of 200km per hour and sometimes more than that, firing as many as 11 aces in the match.
The Czech, who beat Rafael Nadal in 2012 Wimbledon second round, fired five service winners in that game alone after ebbing down 0-40, showing his cool temperament under pressure.
