New York: Novak Djokovic was defaulted in the fourth round of the 2020 US Open on Sunday after hitting a ball in frustration that struck a line judge on the court at Arthur Ashe Stadium.
That line judge was hit in the throat and had to be helped off the court after appearing to have trouble breathing.
Djokovic, a 17-time Grand Slam champion and top seed in US Open, was disqualified from the tournament.
The default came after several minutes where Djokovic pleaded his case to tournament officials that he did not intend to hit the line judge. It was the second time he hit a ball in frustration after a point in the first set of his match against Pablo Carreno Busta, and this one came after Busta broke his serve at 5-5.
Carreno Busta now moves on to the quarterfinals.
