Nick Kyrgios was pitted against Casper Ruud in the second round of the Italian Open having overcome Daniil Medvedev at the first hurdle.
But it was there that his inolvement in the Rome tournament ended as he was disqualified having thrown a chair onto the clay of court three.
Tennis fans across the planet were left wondering what had prompted the show of anger from the 24-year-old world No 36.
Express Sport is here to reveal why Nick Kyrgios acted as he did in scenes which left viewers in Rome and at home taken aback.
Why Nick Kyrgios thew chair
Nick Kyrgios displayed his hotheaded side at the Italian Open by throwing a chair following a furious rant during his showdown with Casper Ruud.
The incident came after the Canberra-born ace had become riled up by spectators walking down the side of the court as he served.
That prompted Kyrgios to launch into an expletive-laden rant as he shouted at a specific member of the crowd in Rome.
Kyrgios then proceeded to walk down the baseline and smash his racket against the ground as he forcefully threw it down.
He then kicked a drinks bottle away, before picking up a chair and throwing it on court, to the amazement of onlooking tennis enthusiasts.
Kyrgios had already been handed a series of code violations by the umpire and his mood had worsened when he handed a break back to Ruud in the third set.
The Italian Open referee was called to court three as Kyrgios packed up his bag, having taken a moment of calm to shake hands with Ruud.
It was then that Kyrgios was disqualified from the tournament, with Ruud advancing to the third round at his expense.
What Nick Kyrgios said
Nick Kyrgios began his rant at an Italian Open spectator by shouting: “F***ing r****d bro.”
Kyrgios then said: “You’re not supposed to walk across the court as I’m serving, do you understand that?
“It’s b********, I don’t want to play when this s**t is going on.”
As he packed his bags, Kyrgios said: “I’m giving 110 [per cent] and having to deal with f***ing idiots like him.
“I’m done, I’m f***ing done. F***ing done with it.”
