Zverev beats Djokovic and wins ATP finals

21-year-old Alexander Zverev celebrated his biggest success so far this Sunday in the final of the ATP finals.

With a 6: 4, 6: 3 against the world number one Novak Djokovic, the German prevented the sixth triumph of the Serbian in the season finale.

Federer was inferior to Zverev in the semifinals and Zverev will improve to fourth in the world rankings.

He showed only once nerves against this year's winners of Wimbledon and the US Open. After winning the first set and then breaking the deadlock in the second, he underwent a weak serve with two double faults and two more simple mistakes.

He caught himself again and took Djokovic the third serve game in a row from. On the way to the final, the ten years older Serbian had not given up a service game and had to fend off only two breakballs. However, Zverev excelled excellently against Federer and surprisingly kept up with more than just the long rallies from the baseline. And suddenly, Djokovic, who had won 35 out of 37 matches since Wimbledon - and never lost to a top ten player - was again human and vulnerable.
