Defending champion Novak Djokovic survived another post-midnight Australian Open epic, storming back to beat sixth seed Alexander Zverev in four sets while Serena Williams advanced to the semi-finals setting up a bloc blockbuster clash against Naomi Osaka.
Djokovic, who is eyeing his ninth title at the event rallied back to win 6-7 (6-8) 6-2 6-4 7-6 (8-6) in Melbourne. The Serbian saved nine of 12 breakpoints, including a set point at 5-6 in the fourth set with an ace, to earn his sixth ATP Head 2 Head victory in eight matches against Zverev.
The 33-year-old has now won 11 straight matches against Top 10 players at Melbourne Park, dating back to his quarter-final loss to eventual champion Stan Wawrinka in 2014. Djokovic will face Russian qualifier Aslan Karatsev in the semi-finals.
Serena Williams bidding to equal Margaret Court’s all-time record made it through to her 40th Grand Slam semi-final after gaining revenge for her Wimbledon final loss to Simona Halep. The 39-year-old American powered her way past Simona Halep in their quarter-final, 6-3 6-3, making amends for the 2019 Wimbledon final where Halep dropped just four games on route to the title.
Serena will now face Naomi Osaka, who beat her in the 2018 US Open final, in the semis. The 2019 champion Naomi Osaka won her 12th consecutive Grand Slam match with a straight-set (6-2, 6-2) victory over Hsieh Su-Wei.
