Nick Kyrgios has been fined $50,000 for his behaviour during a fourth-round loss to Jannik Sinner at the Miami Open in which he lambasted the umpire and smashed his racket.
After repeatedly berating umpire Carlos Bernardes for failing to control the crowd at the Masters 1000 tournament on Tuesday, Kyrgios received a point penalty in the first set tiebreak for telling a friend in the stands he could do a better job officiating.
The Australian then received a game penalty - putting Italian Sinner up a break at the start of the second set - after repeatedly yelling, "What is unsportsmanlike?" to Bernardes, and then walked to his bench, where he whacked his racket repeatedly against his bag and the court.
The ATP said on Thursday Kyrgios was fined $7,000 for audible obscenity, $14,000 for unsportsmanlike conduct and $29,000 for verbal abuse.
Asked after the match about his behaviour, Kyrgios defended his character while railing against the umpire.
"He's not even going to get a slap on the wrist for his dreadful umpiring performance today. Like, he was horrendous," said the Australian.
The incident followed an outburst at Indian Wells earlier this month, where Kyrgios lost his temper after losing in the quarter-final to Rafael Nadal, smashing his racket to the ground, which then bounced up and almost hit a ball boy.
