Just a few sets into his Wimbledon 2015 third round match today and Nick Kyrgios was already living up to his bad-boy reputation.
Although he ultimately went on to win 5-7 7-5 7-6 6-3, the Australian threw a tantrum after losing a point to Canadian Milos Raonic, throwing his racquet at the ground so hard that it bounced up into the stand.
Luckily for the petulant 20-year-old, a member of the crowd was kind enough to retrieve it.
Kyrgios also fell foul of the famously strict dress code at SW19 by wearing a Wimbledon-branded headband with purple and stripes (only white is permitted on court).
To avoid further trouble, he continued to wear the band but turned it inside out.

Wearing hot pink headphones, Kyrgios could be seen peering over the wall - strictly prohibited in case it distracts players.
He was ordered down by security personnel but, true to form, promptly climbed back up as soon as they left.
In just a few days Kyrgios has also managed to fire plenty of verbal volleys at the umpires.

On Monday he appeared to call Mohamed Lahyani “dirty scum” before quickly backtracking and saying he was referring to himself.
And Wednesday saw him rant at Ali Nili, first asking if he was threatening him and continuing: "Does it feel good to be in the chair up there? Does it feel strong to be up there?"
The player was unrepentant in a press conference later that day, putting his behaviour down to an ongoing sinus infection, and said: "I just thought he thought he was top dog in the chair really.
"He was telling me not to speak to him, all that stuff. Doesn't really matter, you know."
Reaction to his antics today was mixed, with some disapproving…
