As usual this season, Novak Djokovic was the best player on the court.
The top-ranked Serb won his fourth straight title at the season-ending ATP finals on Sunday by beating six-time champion Roger Federer 6-3, 6-4.
Djokovic, who won three Grand Slam titles this year and reached the final in the other, capped the best season of his career with another superb display, including winning 16 of the 19 points on his second serve and saving both break points he faced.
"This could not have been a better finish," Djokovic said on court after the match. "Obviously it's been a very long season but the best of my life."
