MELBOURNE: Reigning champion Novak Djokovic overcame several dips in form to beat Alexander Zverev 6-7(6) 6-2 6-4 7-6(6) and book his place in the Australian Open semi-finals yesterday.
The Serbian world number one hit back strongly after losing a tight opening set on a tiebreak but trailed in both the third and fourth sets before turning them around.
Djokovic will face Aslan Karatsev who continued his sensational run at the Australian Open when he stunned Grigor Dimitrov 2-6 6-4 6-1 6-2 to become the fifth qualifier to reach the last four of a men’s Grand Slam in the open era.
The world number 114 regrouped after an error-filled opening set to add the 18th seed to his list of upset victims at Melbourne Park.
Serena Williams came through a huge test of her Australian Open title credentials to reach the last four at Melbourne Park for the ninth time with a 6-3 6-3 victory over Simona Halep in a high quality quarter-final on Tuesday.
The 39-year-old went toe-to-toe with the Romanian second seed over 80 minutes on Rod Laver Arena before she was finally able to move to within two victories of a record-equalling 24th Grand Slam title.
Williams hit some ferocious forehands and moved around the court with a freedom that she has not enjoyed for a good while to set up a semi-final meeting against in-form Japanese third seed Naomi Osaka.
