MELBOURNE (Reuters) – Reigning champion Novak Djokovic overcame some 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 on Tuesday.
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.
Germany’s Zverev will rue allowing Djokovic back from 4-1 down in the third set and he was also up 3-0 in the fourth.
