It wouldn't be a tennis tournament without a Nick Kyrgios blow-up - and this one was one of his worst yet!
As you can see, the 23-year-old used some very colourful language during his two-set loss alongside Taylor Fritz, against Joao Sousa and Guido Pella in the double competition on March 23 at the Miami Open.
“What is wrong with you? You're a disgrace... You're a f---ing disgrace," he can be heard screaming at the umpire in the clip.
Turning to the crowd for support, he quizzed, "Do you think that's alright, yes or no? Just give me the answer. He's a disgrace."
After receiving dull rumblings, he complained, "I come out and give 100 per cent and I have to deal with idiots like him. Does he get fined for his mistakes? It's rubbish, man."
Later, the 23-year-old Australian took to Twitter to label himself "a giraffe" for his actions.
