Kyrgios wins bad-tempered Wimbledon clash with Tsitsipas
The mercurial Australian prevailed 6-7 (2/7), 6-4, 6-3, 7-6 (9/7) in a third-round match during which both players were warned by the umpire.
After sealing his victory in a gripping fourth-set tie-break, Kyrgios said: "The media loves to write that I'm bad to the sport, but I'm clearly not.
"Whatever happens on court, stays on the court. I'm very close to his brothers.
"I felt like I was the favourite. I beat him a few weeks ago and he's only beaten me once. He got frustrated, it's a frustrating sport. Whatever happens, I love him."

In astonishing scenes, the Australian called the umpire a "disgrace", demanding to speak to supervisors and saying he would not continue until the situation was resolved.
"You can't hit a ball into the crowd and hit someone and not get defaulted," he said.
At that point Tsitsipas left the court but returned to boos in an increasingly volatile atmosphere on Court One.
The Australian, who was given an obscenity warning, continued to argue with the umpire at changeovers, saying, in reference to the incident: "If that's a little girl, she cries, what happens?"
Kyrgios, now on top against a clearly rattled Tsitsipas, broke in the fourth game of the third set and held on to take a 2-1 lead.
