Djokovic could not play on through the pain and quit the match after the first set as Zverev reached his first Australian Open final

Novak Djokovic's semifinal match vs. Alexander Zverev at the Australian Open ended far sooner than the Serbian tennis star—or the paying public—would have liked on Friday afternoon at Rod Laver Arena in Melbourne.

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.
