MELBOURNE - Serbia's Novak Djokovic, the world number one in men's tennis singles, on Tuesday completed his first training session at the Rod Laver Arena in Melbourne ahead of Australian Open, the season's first Grand Slam tournament.

Reigning champion Djokovic recently arrived in Melbourne from Perth, where he played for Serbia at the United Cup.

Djokovic won seven titles in the just ended season, including three Grand Slam trophies, along with playing in the Wimbledon final.
As in 2015, Novak won three slams and the ATP final, he also finished the year as the number one in the world, but Mouratoglou believes that this last season is even better than the one eight years ago.

TURIN - Serbia's Novak Djokovic, the world number one in men's tennis, is through to the semi-finals of the ATP Finals in Turin after Italian Jannik Sinner defeated Dane Holger Rune 6-2, 5-7, 6-4 in a Green group third round match on Thursday evening.

Previously, title holder Djokovic beat Pole Hubert Hurkacz 7-6 (7-1), 4-6, 6-1.

TURIN - Serbia's Novak Djokovic, the world number one in men's tennis, defeated Pole Hubert Hurkacz 7-6 (7-1), 4-6, 6-1 in an ATP Finals Green group third round match in Turin on Thursday but now needs a Jannik Sinner victory over Dane Holger Rune to qualify for the semi-finals.

Hurkacz entered as a substitute for Stefanos Tsitsipas and will play against Novak Djokovic on Thursday at 2:30 p.m.
The day before, Hurkacz was training in the "Pala Alpitour" hall, when a little boy asked him for a racket.
"If I beat Novak, I'll give you a racket," Hurkacz said.

TURIN - Serbia's Novak Djokovic, the world number one in men's tennis, lost to Italian Jannik Sinner 7-5, 6-7 (5-7), 7-6 in the second round of the ATP Finals Green group in Turin on Tuesday evening.

Sinner registered his first-ever win against Djokovic after over three hours of play and is now 1-3 head-to-head against the Serbian.

Stefanos Tsitsipas withdrew from the ATP Finals with a back injury on Tuesday after playing only three games of his second match in Turin, handing Holger Rune the victory.

Tsitsipas, the 2019 champion, was trailing 2-1 in the opening set when he had a lengthy conversation with his trainer before slowly getting to his feet, shaking his head and walking over to shake Rune's hand.

From 9:00 p.m., Djokovic is expected to have a duel with the Italian Jannik Sinner, the fourth ranked tennis player in the world.
For the Italian, it is the best ranking on the ATP ranking in his career, and the 22-year-old has won four titles this year, for a total of ten.
At the opening of the tournament, Sinner defeated Greek Stefanos Tsitsipas 6:4, 6:4 in two sets.

TURIN - Serbia's Novak Djokovic, the world number one in men's tennis, beat Dane Holger Rune 7-6 (7-4), 6-7 (1-7), 6-3 in the first round of the ATP Finals Green group in Turin on Sunday evening, securing his eighth career end-year number one spot in the ATP rankings.
