Novak Djokovic recovered from early breaks in both sets to beat Roger Federer 7-6 (6), 7-5 today in the championship match at the ATP finals.
Federer broke Djokovic's serve to take a 2-0 lead in the first set, and then again to open to the second set, but both times the top-ranked Serb rebounded to get back into the match.
It was Djokovic's second victory at the year-end tournament for the top eight players in the world. He also won in 2008, when the tournament was in Shanghai.
Federer had been looking for his record seventh title.
