Novak Djokovic became the first player to qualify for this year's ATP Finals after the world number one tied Roger Federer and Rafael Nadal's record with his 20th major at Wimbledon on Sunday.

Djokovic defeated Italy's Matteo Berrettini 6-7(4), 6-4, 6-4, 6-3 in the final to seal a sixth Wimbledon title and qualify for the November 14 to 21 ATP Finals in Turin.

"I am happy to have qualified for Turin so early," Djokovic, who will play in his 14th ATP Finals, said in a statement.

"Italian fans are very much into tennis so I am sure it will be a great event with a fantastic atmosphere."

The Serbian will look to win the season finale for the sixth time, aiming to match Swiss ace Federer's record at the event.

The 34-year-old, who is on course to finish the year as the top-ranked player for a record-breaking seventh time, has won 34 out of 37 matches this year.
