Novak Djokovic retired from the Australian Open semifinal against Alexander Zverev after losing the first set 7-6, citing a torn muscle in his left leg. This injury, sustained in the previous match against Carlos Alcaraz, led to booing from spectators as he left the court. Djokovic, 37, spoke of the pain worsening and expressed uncertainty about his future in the sport, despite a desire to continue. Zverev advanced to the final, where he will face defending champion Jannik Sinner, who defeated Ben Shelton.
