Novak Djokovic conceded just one game as he routed Lukas Rosol in the second round of the Miami Masters.
The world number one looked in imperious form as he raced to a 6-1 6-0 victory in just 53 minutes.
Rosol created two break points in the opening set, but he couldn't take either of them, and Djokovic took full advantage to power through the set.
It was even more comfortable in the second, sealing three breaks of serve as Rosol made as many as six double faults, and the match was sealed seven minutes short of the hour.
Djokovic will now play India's Somdev Devvarman in the next round.
