Top-seeded Serbian Novak Djokovic beat Frenchman Jo-Wilfried Tsonga 7-6 6-2 on Sunday to win his third China Open tennis title in Beijing.
World No2 Djokovic dug deep in the first set after an early trade of breaks to win a close tie-breaker and then broke the third-seeded Tsonga
twice in the second set.
"I think the first set was really even and maybe a couple of points decided the winner there," Djokovic told reporters.
"We both had our chances aside from those breaks that we converted... I managed to hold my nerve in the end.
"I made that early break in the second (and) I felt much more comfortable on the court."
Sunday's victory gave Djokovic, who also won the China Open in 2009 and 2010, his fourth title of the year.
The 2012 Australian Open champion will remain in the hunt to take back the world number one ranking from Roger Federer at the end of the year.
