Nick Kyrgios' 'frightening' moment with young fan after meltdown

Mark Woodforde says seeing young fans idolising Nick Kyrgios after his meltdown in Cincinnati was “frightening” and “troubling”.

Kyrgios copped the biggest fine in ATP history on Thursday, docked $US113,000 ($A167,000) by the ATP after losing the plot with a number of ugly offences against Karen Khachanov.

The fines included five charges of unsportsmanlike conduct totalling $US85,000, $US20,000 for verbal abuse, $US5,000 for audible obscenity and $US3,000 for leaving the court without permission.

"The ATP is looking further into what happened during and immediately after the match to see if additional action is warranted under the Player Major Offense section of the code. That could result in an additional fine and/or suspension," the game's governing body added.

Woodforde was gobsmacked by the ugly scenes, but was even more shocked to see how young fans reacted after Kyrgios disgraced himself.

Many gathered near the court as Kyrgios gave away his shoes, while one youngster was overjoyed after receiving one of the racquets Kyrgios had obliterated.

The fact that young fans are idolising Kyrgios is all the more reason for the ATP to suspend him, says Woodforde.

“What was frightening for me was the kids after the match leaning over the fence around centre court wanting Kyrgios’ shoes, they were wanting the mangled rackets”, Woodforde told 5AA Radio on Friday.

“That shouldn’t be happening after the display he displayed. That to me is troubling. That’s not the model for young kids.

“This is a habit now for Nick. It’s not really getting any better… the level of his outbursts are starting to get a little bigger and it’s disappointing.”

Kyrgios’ latest indiscretion

The 24-year-old Australian won the opening set against his Russian opponent, despite foot and ankle issues, before unleashing a profanity-laced tirade at umpire Fergus Murphy, throwing his towel over a camera and forcing broadcasters of the US event to switch to an overhead view.

Kyrgios took umbrage with Murphy, who he has previous history with, over his monitoring of the shot clock and berated the Irishman for most of the match.

He became obsessed with the issue, repeatedly calling Murphy a "potato" and labelling him a "disgrace" and the "worst ref in the world".

Murphy eventually responded by handing Kyrgios a point violation after Khachanov won the second-set tiebreaker to level the match, when the Canberran overstepped the mark by screaming out an obscenity.

Kyrgios then followed this up by asking for a toilet break. He took two racquets with him and smashed them in the players' tunnel before returning to the court.

After a double-fault handed Khachanov the match and the players shook hands, Kyrgios told Murphy "you're a f***ing tool bro" and appeared to spit in the direction of the umpire before he shunned the traditional handshake.
