The ATP is set to increase punishments for on-court misconduct in the wake of Nick Kyrgios’ latest outburst.

The men’s governing body has told players it was also reviewing its penalties for serious violations and repeat offenders.

The ATP told players the incidents “shine a bad light on our sport”.

“Effective immediately and as we head into the clay court swing, the ATP officiating team has been directed to take a stricter stance in judging violations of the code of conduct,” ATP chairman Andrea Gaudenzi said.

“Additionally, we are also undertaking a review of the code, as well as the disciplinary processes, to ensure that it provides appropriate and up-to-date penalties for serious violations and repeat offenders.”

Kyrgios was fined a total of $60,000 after outbursts at both Indian Wells and the Miami Open recently and Alexander Zverev was kicked out of the Mexican Open after hitting the umpire’s chair with his racquet.

“The first three months of the season have seen an unusual frequency of high-profile incidents involving unsportsmanlike conduct,” Gaudenzi said.

“This conduct affects everyone, and sends the wrong message to our fans, especially young fans.”
