MELBOURNE: Defending champion Jannik Sinner blew past Ben Shelton 7-6 (7/2), 6-2, 6-2 in the Australian Open semi-finals on Friday to set up a showdown with Alexander Zverev for the title.

The top-ranked Italian will face the German second seed, who went through to Sunday's final when Novak Djokovic retired injured from their last-four clash.

Sinner had to save two set points in a tight opening act, but once he took it on a tiebreak he raced past the 22-year-old in 2hr 36min on Rod Laver Arena, despite cramping late in the match.

The centre court crowd had been disappointed earlier when Djokovic called it a day after losing a grueling first set against Zverev, leaving his bid for a record 25th Grand Slam crown in tatters.

The 37-year-old Serbian great's upper left leg was heavily taped and, after he shook hands, he departed to some boos after going down 7-6 (7/5).

Djokovic hinted that he may have played his last Australian Open.

"There is a chance. Who knows?" Djokovic said when asked if he may have graced the Melbourne Park courts for a last time.
