After smashing his racket repeatedly against the umpire's chair, world number three Alexander Zverev was kicked out of the ATP 500 tournament in Acapulco for "unsportsmanlike conduct."
After he and Brazil's Marcelo Melo lost 6-2 4-6 (10-6) to Lloyd Glasspool and Harri Heliovaara, the German later apologized for his actions.
During his horror in Mexico, Zverev was dangerously close to threatening the CEO of Alessandro Germani.
Alexander Zverev has been withdrawn from the tournament in Acapulco due to unsportsmanlike conduct at the conclusion of his doubles match.
Zverev said he regretted his actions.
"It's difficult to understand how much I regret my behaviour during and after the doubles match," Zverev said in a statement.
"I have privately apologised to the chair jurpire because my outburst against him was erroneous and unacceptable, and I am only depressed about myself.
"It should not have happened, and there is no reason. I would apologise to my supporters, the tournament, and the sport that I love."
Zverev, 24, ranked third in the singles, approached the juror's chair and slapped it repeatedly before heading to his courtside seat, being upset by a line call earlier in the match.
Immediately after approaching the chair, he pushed it again while chanting expletives.
On Tuesday, the former U.S. Open finalist completed a first-round singles victory against American Jenson Brooksby, the most recent outcome in a professional tennis match.
Zverev, the winner of last year's tournament, had been scheduled to meet with fellow German Peter Gojowczyk, who will now get a walkover to progress to the quarter-finals.
Novak Djokovic, the world's number one, spoke about the incident in Dubai where he is playing, said the disqualification was correct, but offered some help to Zverev.
"I've made mistakes in the past where I've had disagreements on the court," Djokovic told reporters. "I understand what the player is going through. But, of course, I do not justify his actions. I think the decision of disqualification was not too harsh. It was correct under the circumstances."
After losing a point, Djokovic was disqualified from the 2020 US Open.
Andy Murray, the former world number one, was also competing in Dubai. He described Zverev's retaliation as "dangerous and retaliation."
"Although you're throwing your tennis racquet right next to the umpire many times, you're not in charge," he said.
Following an internal investigation, Zverev's dismal outburst might result in additional penalties from the ATP. In 2019, Nick Kyrgios, an Australian, was sentenced to a 16-week suspended sentence and an additional fine of $25,000.
In October last year, the ATP launched an internal investigation into allegations of domestic abuse against Zverev, led by his ex-girlfriend Olga Sharypova.
