Nick Kyrgios added another chapter to his colorful, and off-color, career on Thursday when he was disqualified from his second-round match at the Italian Open in Rome after hurling a chair onto the court in rage.

Kyrgios was in the third and deciding set against Casper Ruud when he became rattled by spectators moving in the stands, particularly during his service motion. He complained to officials and, loudly, to his own coaching team, causing him to receive a penalty for unsportsmanlike conduct.

It was his third code violation of the match, meaning he forfeited a game. Earlier, he was penalized first for ball abuse and then for unsportsmanlike conduct, which cost him a point.

The game penalty led Kyrgios to go on a tirade. He spiked his racket, kicked a water bottle and threw the chair into the middle of the court.

“I’m giving 100%, and I have to deal with idiots up here,” Kyrgios shouted along with a profanity and an unfavorable opinion of the officiating. “I’m done.”

He packed up to leave as his official disqualification was announced. The crowd — which several games earlier was joyfully chanting for Kyrgios, with his encouragement — booed and hissed. Kyrgios did not speak to the news media after the match.

But in an Instagram post a few hours later, Kyrgios wrote: “Emotions got the better of me and I just wanted to say that the atmosphere was crazy out there today, just super unfortunate that it had to end in a default. Sorry Roma, see you again, maybe.”

The default, a severe penalty rarely imposed in tennis, carries with it the loss of all prize money and ranking points earned at the tournament and the possibility of further punishment. According to the ATP, Kyrgios was fined 20,000 euros (about $22,350) and forfeited 33,635 euros in prize money and 45 ranking points. He must also pay back his hospitality costs for the tournament.
