Reactions were mixed after Novak Djokovic’s disqualification from the U.S. Open for striking a line judge with a ball during his match against Pablo Carreno Busta on Sunday.

Following the incident, the US Tennis Association issued a statement saying that Djokovic would lose all the ranking points earned from the event.

He will also be fined the 250,000 dollars prize money for reaching round four.

“In accordance with the Grand Slam rulebook, following his actions of intentionally hitting a ball dangerously or recklessly within the court or hitting a ball with negligent disregard of the consequences, the US Open tournament referee defaulted Novak Djokovic from the 2020 US Open.

“Because he defaulted, Djokovic will lose all ranking points earned at the US Open and will be fined the prize money won at the tournament in addition to any or all fines levied with respect to the offending incident,” the statement said.

Busta was left in shock after the incident, saying, “I never expected this moment playing against Novak. So, it was a tough moment also for me.

“I think this was not intentional,” the Spaniard told reporters. “I don’t think that anyone of us, the players, do this (intentionally).

“It’s just I broke his serve and he threw the ball. I think that it was bad luck, no? You cannot do this, but of course, I think that Novak never, never wants to hit the line umpire.

“I’m so sorry about that because it’s not the way that I want to be in (the) quarter-finals.”
