Djokovic to go for back-to-back China titles after beating Tsonga to reach Shanghai final

Defending champion Novak Djokovic advanced to the final of the Shanghai Masters on Saturday with a 6-2, 7-5 win over France's Jo-Wilfried Tsonga.

The top-seeded Serb extended his winning streak in China to 19 straight matches dating back to last year when he won the China Open in Beijing and then Shanghai. He successfully defended his China Open title last week, and will try to do the same in Shanghai on Sunday.

Tsonga came out looking flat and misfiring wildly at times on his groundstrokes and volleys. He finished with 35 unforced errors and only managed to win 13 of 31 points at net.

Rafael Nadal, who lost to Djokovic in the Beijing final, plays Juan Martin del Potro in the other semifinal later Saturday.
