Andy Murray earned the year-end No. 1 ranking and his first title at the ATP finals on Sunday, beating Novak Djokovic 6-3, 6-4 in the last match of the tennis season.
The Wimbledon champion, who took over from Djokovic as the top-ranked player two weeks ago, needed to win on Sunday to ensure he finished the season as the No. 1-ranked player in the world for the first time.
Murray started with a pair of double-faults in the opening game, but it was soon Djokovic that was struggling with his serve. The second-ranked Serb was broken once in the first set and twice in the second as the unforced errors piled up.
