Djokovic had just been broken at 5-5 in the first set against Pablo Carreno Busta when the world No. 1 struck a ball behind him on the court hitting the lines woman.The woman cried out and then collapsed to the ground where she stayed for several minutes trying to catch her breath. It was obvious the ball strike was not intended to hit her however the consequence was harsh and by the book.A lengthy discussion ensued between chair umpire Aurelie Tourte and two tournament officials in Arthur Ashe Stadium and then the decision…Djokovic is defaulted out of the US Open.Novak Djokovic just got disqualified from the US open for hitting a line judge in the neck. wtf pic.twitter.com/PLTgDwzZ0w— SAVAGE BOSTON (@SavageBoston) September 6, 2020 Moments earlier, the tightly-wound world #1 had smacked a ball in frustration when he was unable to convert three set points at 5-4.
