Novak Djokovic admitted he got “extremely lucky” as Lorenzo Musetti retired injured from their Australian Open quarter-final while two sets up, sending the 38-year-old through to another semi-final showdown with defending champion Jannik Sinner.
Musetti raced into a 6-4 6-3 lead, playing brilliant tennis, but began to struggle after noticing pain in his leg at the beginning of the second set. The issue became worse at the start of the third, leaving Musetti unable to run, and he retired while 3-1 down.
