Nick Kyrgios showed the contrasting sides of his character again during his third round win over Ivo Karlovic at the Miami Open overnight.
The tempestuous Australian drew boos from the crowd midway through the match for appearing to reprimand a ball boy.
The 21-year-old was unhappy with the way the ball was thrown at him and, never a man to conceal his emotions, let it be known how he should have received it.
Kyrgios was serving in the second set when he said: "How am I supposed to catch that" at the ball boy before adding: "It's right at my feet". It was a response that saw a minority of fans turn on the flamboyant Aussie.
Kyrgios used that negative energy to good effect and even won the crowd round by the end of his 6-4, 6-7 (7-4), 7-6 victory at Key Biscayne.
In true Kyrgios fashion he threw in one of his accustomary 'tweeners' en route to reaching the fourth round.

At the conclusion of his victory, which continues his good run on the outdoor hard courts this season, Kyrgios sought out the bad boy he had told off to smooth things over.
In a touching exchange, Kyrgios turned the boy's baseball cap around and handed him one of his towels as a memento of the evening.

The 12th seeded Krygios, who knocked Novak Djokovic out of Indian Wells last week only to pull out of a meeting with Roger Federer due to illness, will now face David Goffin for a place in the quarter-finals.
Kyrgios is not the first player to lash out at a ball boy in Miami. Two years ago Djokovic made an apology after a ball boy was caught in the middle of the Serbian's scream towards his camp.
Djokovic said of the incident at the time: "I saw the replay. Unfortunately a ball boy was in the middle of it and I really, really feel sorry and regret that he was there. There was absolutely no intention whatsoever to hurt him or scare him in any kind of way. I sincerely hope he forgives me. I really apologise."
Djokovic pulled out on the eve of this year's tournament with an elbow injury.
