World number one Roger Federer secured his sixth ATP title of the year with a 6-0 7-6 win over Novak Djokovic in the Cincinnati Open final on Sunday.
It took Federer just 20 minutes to clinch the first set but it was a tighter affair in the second which Federer won 9-7 in the tie-break.
It is the fifth time Federer has won the Cincinnati event and the third time in four years.
Neither player had dropped serve all week but Djokovic started sloppily, with Federer breaking in the opening game.
Djokovic, who earned quick revenge for his Olympic defeat to Juan Martin del Potro with a 6-3 6-2 success yesterday, could not recover and Federer broke twice more to surprisingly wrap up the opening set in convincing fashion after just 20 minutes.
Federer was in opportunistic mood, converting three of four break-point chances although Djokovic only put 50% of his first serves in play and aided his opponent's cause with four double faults.
It was the first time Federer had "bagelled" the Australian Open champion and perhaps stung into action, Djokovic looked a lot more comfortable in a tighter second set, where there were no break point opportunities for either player.
In the tie-break, the 25-year-old Serb held set point at 7-6 but it was ruthlessly wiped out by some attacking play at the net from Federer, who then closed out the match with two spectacular forehand winners.
