The Greek Stefanos Tsitsipas qualified for the semifinals of the Australian Open by beating the Czech Jiri Lehecka (n.71 Atp) in three sets with a score of 6-3, 7-6, 6-4.
It's the fourth time the 24-year-old from Athens, No. 4 in the world, has reached the semi-finals in Melbourne, but he has never managed to go further.
His next opponent will be the Russian Karen Khachanov (n.20).
And four months after the first Grand Slam semifinal played in Flushing Meadows, the Russian Karen Khachanov also reaches the semifinal at the Australian Open thanks to the withdrawal of the American Sebastian Korda, forced to hoist the white flag, on a score of 7-6 6-3 3-0 in favor of his rival, due to a problem with his right wrist.
The injury actually occurred at the end of the fifth game of the second set, with Korda ahead 3-2.
The American called the physiotherapist but from that moment he was no longer able to handle the exchanges (especially with the forehand and return) giving up 7 consecutive games until he was abandoned.
Friday the challenge between Khachanov and Tsitsipas
Among women, Victoria Azarenka reaches the semifinals.
The Belarusian defeated the American Jessica Pegula 6-4, 6-1 in two sets.
Waiting for her will be Kazakh Elena Rybakina, reigning Wimbledon champion, who beat Latvian Jelena Ostapenko for the first time and qualifies for the semifinals of the Australian Open for the first time in her career.
The Kazakh, seeded number 22, prevailed leaving just 6 games (6-2 6-4) to the 2017 Roland Garros champion.
