Novak Djokovic has deemed the tour's decision to disqualify Alexander Zverev from the Acapulco tournament as "correct" while Andy Murray described the German's racquet-smashing spree as "dangerous" and "reckless". Djokovic, playing his first tournament since his deportation from Australia, continued his fight to keep his number one ranking with a convincing 6-3, 7-6 (7/2) victory over Karen Khachanov in Dubai to move into his 10th consecutive quarter-final on Wednesday. The Serb later weighed in on Zverev's violent behaviour towards a chair umpire that got him kicked out of the ATP event in Acapulco.
