The ATP have fined Nick Kyrgios a total of $113,000 (£93,000) following his second-round loss at the Cincinnati Masters on Wednesday, when the Australian argued loudly with the chair umpire and smashed several rackets.
The fines included five charges of unsportsmanlike conduct totalling $85,000, $20,000 for verbal abuse, $5,000 for audible obscenity and $3,000 for leaving the court.
“Following his second-round loss at the Western and Southern Open in Cincinnati [on] Wednesday night, Nick Kyrgios was fined $113,000," the governing body said in a statement.

In addition to the on-site fines, the ATP is looking further into what happened during and immediately after the match to see if additional action is warranted.
"That could result in an additional fine and/or suspension.

Kyrgios accused Murphy of starting the shot clock too early and was ultimately issued a point penalty at the end of the second set tiebreak for insulting the Irish umpire using an expletive and shouted that Murphy was "the worst ref ever."
The 24-year-old then left the court for what he deemed a bathroom break, despite protests from Murphy, and television pictures showed him smashing his rackets in a tunnel.
Kyrgios left the court without shaking Murphy's hand.
A suspension could impact his ability to compete at the U.S. Open although it is unclear whether the tournament organisers would honour the suspension if it is handed down.
He had clashed with the Irish official two weeks ago at the Washington Open and was also fined by the ATP after being embroiled in an expletive-ridden rant with Murphy at the Queen's Club Wimbledon warm-up tournament in June.
