Djokovic, who retired due to injury after the first set, was booed by the crowd as he walked off Rod Laver Arena.

Novak Djokovic has reacted to the crowd at the Australian Open booing after he decided to retire from his semifinal against Alexander Zverev. The Serbian tennis player, 37, had taken to the court with his left leg heavily taped following Tuesday’s injury.

Novak Djokovic is out of the Australian Open in stunning fashion. The 24-time slam champion medically retired immediately after dropping the first set of his semifinal match against No. 2 Alexander Zverev in a tiebreak 7-6 (5).

Defending champion Jannik Sinner continued his sizzling Australian Open run with a 7-6(2) 6-2 6-2 win over American 21st seed Ben Shelton to reach a second straight final at Melbourne Park and book a meeting with Alexander Zverev.

World No. 1 Jannik Sinner Friday became the youngest man to reach back-to-back Australian Open finals since Jim Courier in 1992.

The Australian Open women’s tournament will have a fitting conclusion this weekend as history is set to be made in one way or another. World No. 1 and two-time defending champion Aryna Sabalenka will square off against Madison Keys in a clash of the heavyweights.
