Stefanos Tsitsipas

Djokovic's opponent will be Tommy Paul, an American with whom he has not met so far in his career.
This is Novak's 10th time playing in the semi-finals of Melbourne, and he has been successful in all previous ones.
Djokovic has been pretty confident so far in the tournament, despite the hamstring injury.

Stefanos Tsitsipas produced a blockbuster performance to reach the Australian Open semi-final on Tuesday then sent out an invitation to actress Margot Robbie to come and support him.

Stefanos Tsitsipas reached the Australian Open semi-finals for the fourth time as the Greek saw off rising Czech Jiri Lehecka 6-3 7-6(2) 6-4 on Tuesday.

The third seed dominated the opening set after breaking a nervy Lehecka early on but was pushed hard after that against the 21-year-old who has enjoyed a breakout tournament.

Stefanos Tsitsipas found another gear when it counted to fend off Jannik Sinner in a five-set thriller and reach the Australian Open quarter-finals in a rare win for the high seeds this Sunday.

Third seed Stefanos Tsitsipas made short work of Dutchman Tallon Griekspoor, winning 6-2 7-6(5) 6-3 to reach the fourth round of the Australian Open on Friday, shortly after organizers defended their schedule after the previous day's late finish.

A dominant Stefanos Tsitsipas proved a step too far for home hope Rinky Hijikata as the Greek third seed eased into the Australian Open third round with a 6-3 6-0 6-2 win on Wednesday.

Wildcard Hijikata, ranked 169th in the world, went toe to toe with Tsitsipas in the early exchanges and looked capable of making it a contest for the Rod Laver Arena crowd.

Serbian tennis player Novak Djokovic won the tournament from the 500 series in Astana, defeating Greek Stefanos Tsitsipas with a score of 6:3, 6:4.
In this way, Novak Djokovic won the jubilee ninetieth title in his career.
Thus, World No. 7 celebrated in competitions from the 250, 500, 1000 series, and at the Grand Slam, Wimbledon.

He reached the victory after being two sets down and a big comeback.
"From the start of the third set, I played three really very solid, very high-quality tennis sets," he said simply. "From the very beginning of the third when I broke his serve early, I felt that I found my rhythm and tempo on the shots", Novak said.

Stefanos Tsitsipas said Nick Kyrgios has an "evil side" after a stormy clash at Wimbledon in which the victorious Australian called for his Greek opponent to be kicked out of the tournament.

The bad-tempered match overshadowed the rest of the action on day six, which included the end of Iga Swiatek's 37-match winning streak and a routine victory for Rafael Nadal.
