World number 1 Novak Djokovic was sensationally disqualified from the US Open on Sunday after striking a female lines official in the throat with a ball
The world number one went 5-6 down in the first set to Spain’s Pablo Carreno Busta when he pulled a ball out of his pocket and hit it in disgust in the direction of the official.
Djokovic appeared to be looking away from the official at the time, but he hit the ball with considerable force and when it struck her she could be heard gasping and coughing.
The official fell to the floor of the Arthur Ashe court clutching her throat.
Djokovic rushed over to check that she was okay. He put his hand on her shoulder as she appeared to be struggling to catch her breath.
After a few minutes she got up and walked off the court.
Following around ten minutes of discussions with a rules official, during which Djokovic argued his case, the umpire declared that Carreno Busta had won by default.
Djokovic then shook hands with Carreno Busta but not with the official in the umpire’s chair as he left the court looking bewildered.
He quickly exited Flushing Meadows without speaking to reporters.
Carreno Busta said he did not see the incident.
“I was celebrating the break with my coach,” he told reporters.
“When I heard that the line judge was on the floor I was in shock. I never expected this moment when playing Novak.
Carreno Busta added that the incident was “unintentional.”
“I think it was bad luck,” he said.
Djokovic is one of only a handful of players to be disqualified from a men’s singles tournament at a Grand Slam since John McEnroe was infamously tossed from the Australian Open in 1990.
The United States Tennis Association said he would lose all ranking points and prize money from the tournament.
Djokovic had been chasing an 18th Grand Slam title at the Billie Jean King US National Tennis Center.
He was hoping to close the gap on Roger Federer and Rafael Nadal, both absent from the tournament, in the race for the all-time men’s Slam singles title record.
Djokovic is on 17, with Nadal on 19 and Federer on 20.
