In a stunning development at the Australian Open, Novak Djokovic withdrew because of injury after losing the first set of his semifinal match versus Alexander Zverev. Zverev, the No. 2 seed, won a grueling first set in a 7–6 tiebreaker that lasted one hour and 26 minutes.

Novak Djokovic’s bid for an 11th Australian Open title ended abruptly on Friday (January 24th). Hoping for a record 25th Grand Slam title, the Serbian veteran left off a tiresome 80-minute Rod Laver Arena first set 7-6 (7-5).

Djokovic sustained a muscle tear in his upper left leg during his quarter-final victory over Carlos Alcaraz on Tuesday and admitted he did not have anything left in the tank after attempting to play through the pain.
