Tennis:Novak Djokovic defeats Jo-Wilfried Tsonga to win Shanghai Rolex Masters

Novak Djokovic cruised to the Shanghai Rolex Masters title with victory in the final against Jo-Wilfried Tsonga.

The 6-2 6-4 win brought up back-to-back wins in Chinese events for the world's top player, who was also successful in Beijing last week.

Djokovic extended his winning record to 17 consecutive matches and 21 sets in a row as he captured his ninth title of the year in one-sided fashion.

Chinese fans had barely settled into their seats when, after less than two minutes, Djokovic had already established a 2-0 advantage having broken in the very first game of the final then raced through a service game as if it were a training drill.

Tsonga, with the ball in hand for the second time, was still afforded no time to settle into his surroundings and found himself camped behind his baseline as Djokovic ruthlessly broke his serve again.

The final was in danger of appearing beyond Tsonga already yet he improbably broke as Djokovic's concentration waivered - it was a brief interlude as the world No 1 broke for a third consecutive time to go 4-1 up.

Four set points were saved as Tsonga held for the first time but the set was wrapped up inside a 30-minute avalanche.

The world No 15 impressively refused to be bullied anymore, finding a rhythm with his serve and a place for his powerful forehand as the second set proved far more competitive.

But in the ninth game, with Tsonga on serve, the pressure was cranked up a notch. The Frenchman defended two break points but it was third time lucky for Djokovic who crucially gave himself the chance to serve for the trophy, which he took.

The Shanghai title was Djokovic's fifth ATP Masters 1000 crown of the year and the 25th of his career.

"Today the key was to get as many serves back into play to Jo because he has one of the biggest serves in the game," Djokovic said.

"He showed that in the second set, with some break points early in the set. He came up with some aces, some big serves.

"Generally I felt always in control of the match. I felt like I did everything right and I didn't allow him to get into the rhythm, get into the match."
