Novak Djokovic beats Jo-Wilfried Tsonga in Shanghai Masters final

Novak Djokovic has won the Shanghai Masters title three times

Novak Djokovic underlined his position as world number one with a dominant display to beat Jo-Wilfried Tsonga in the final of the Shanghai Masters.

The Serb was too good for his French opponent, winning 6-2 6-4 in 78 minutes at the Qi Zhong Stadium.

It is the 28-year-old's ninth title of a season in which he has also won three of the four Grand Slams.

Djokovic, who has won his last 22 sets, is unbeaten in 17 matches, dating back to the start of the US Open.

He now has 25 Masters titles - one more than Swiss Roger Federer and two fewer than record-holder Rafael Nadal of Spain.

Tsonga, who saw off Nadal in the semi-finals, came into the match having served 64 aces in the tournament, but Djokovic broke the 30-year-old four times and prevented him hitting a single ace in the first set.

Djokovic was broken once himself in the opening set, but by then he was 3-0 up. He gave his opponent few chances afterwards.

Tsonga survived five break points in the second set until 10-time Grand Slam winner Djokovic was finally able to convert on his sixth when the Frenchman double-faulted while serving at 4-4. Djokovic made no mistake on his own serve.

The Serb now has 14,285 points in the 2015 Race to London, 6,415 more than second-placed Andy Murray, who he beat in the last four in Shanghai.

In Sunday's final of the Tianjin Open, second seed Agnieszka Radwanska of Poland beat Montenegrin Danka Kovinic 6-1 6-2.
