Novak Djokovic won the title for the fourth consecutive year thanks to a 6-3, 6-4 victory over Roger Federer

LONDON – Novak Djokovic put the finishing touch to a magnificent season by beating Roger Federer 6-3 6-4 to win the ATP World Tour Finals on Sunday for the fifth time in his career.

The Serbian underlined his complete dominance of men’s tennis with another immaculate display to become the first player in the year-ending tournament’s 46-year history to triumph four times in a row.

“There are different types and levels of domination, and throughout the week in London, Novak Djokovic gradually hit the highest level of all. He dominated quietly. Without fanfare. Implacably. Inarguably. Almost serenely” , writes Peter Bodo in ESPN Sports.

Federer, who pulled out of the final against Djokovic last year with a back injury, brought the tournament to a close in anticlimactic fashion once again, double-faulting on the final point.

After a modest celebration, Djokovic walked to his chair and wrote, “And now for vacation,” in Serbian on a camera lens.

The top-ranked Djokovic, 28, won three of the year’s four Grand Slam tournaments, beating Andy Murray in the Australian Open final and Federer in the Wimbledon and United States Open finals. He lost to an inspired Stan Wawrinka in the French Open final.

The 28-year-old has stomped through the season to leave his rivals trailing in his wake — securing the year-end world number one ranking weeks before the London finale.

He won three of the year’s four grand slams, beating the evergreen Federer in the Wimbledon and U.S. Open finals to take his career haul to 10, and would have celebrated the rarest of ‘calendar year slams’ had it not been for an inspired Stanislas Wawrinka in the French Open final.

“I returned more balls back than I did five days ago,” Djokovic told a news conference.

“Obviously sitting here with this trophy alongside me, I couldn’t ask for a better finish of the season.

“This season definitely stands out. I can’t say I expected it, not at all. But I always gave my best, and I’m always asking from myself the most.”
