World number one Novak Djokovic crushed Tomas Berdych 6-0, 6-2 Sunday to win the China Open and maintain a remarkable 100 percent record in the Beijing tournament.

Serb Djokovic was 5-0 ahead in the second set, one game from serving up an incredible "double bagel" as he tore through his Czech opponent with a brilliant serving display.

As he was staring at an embarrassing defeat, a stunned Berdych laughed as he pretended to hand his racket to a ball-girl, suggesting that she may be able to take on his opponent.

But the world number six rallied briefly to take Djokovic's serve and then take the scores to a more respectable 5-2, before the reigning champion sealed his fifth title in Beijing, an event he has won the five times he has entered.

"Beijing is definitely my lucky place, I enjoy coming here," Djokovic said to the crowd after his stunning victory over the third seed.

In the women's final, it was a gritty performance from current world number four Sharapova, who handed Kvitova her first loss in nine games.
