But a poor service game from the Aussie put paid to that plan.

Djokovic 6-1 6-4 6-4 Machac
Job done!
An interesting match as Novak Djokovic contended with what appeared to be illness and a frustration with the crowd to make it to the fourth round in straight sets.
Tomas Machac showed glimpses of turning that into a great competition but it didn't quite live up to that in the end.
