The fiery Australian was embroiled in an ongoing verbal battle both with himself and with chair referee Carlos Bernardes who completely undermined his performance in a tough match at first.
Instead, Sinner remained cool and fully focused to close a place in the quarterfinals with a 7-6 (3) 6-3 victory.

He continued: “Today, I raised my level a little. I tried to play a little more aggressively. The conditions are a little easier, it does not blow so much. I tried to stay close to the lines. I served well and in important moments. “It can give me a lot of confidence for the next round.”
Sinner, who saved a total of eight fight points in his victories over Emil Ruusuvuori and Pablo Carreno Busta earlier in the week, left a few explosive winners early in the competition to indicate that the crowd on the podium was enjoyable. .
The 20-year-old Italian then came under intense pressure as he was forced to block break points in consecutive serve games.
Kyrgios was visibly disappointed with the missed opportunities and started coming out with a trademark style. Initially, he criticized the speed of the field, indicating that it was much slower than in the Stadium, where he had comfortably seen Andrei Rublev and Fabio Fonini in his previous matches.
“It is completely different,” Kyrgios said. Do you think someone will tell the players that it is completely different before the tournament starts or “Hello guys, let me tell you, the main stadium is completely different from the stands for some strange reason.” What a joke. “
The No. 102 in the world focused again in time to save two break points at 4-4, but was annoyed by the intensity of the referee’s walkie-talkie at the end of the next match as Sinner put pressure on the scoreboard.
“Incredible!” he screamed as he sat in his chair. “It’s the fourth round in Miami – one of the biggest tournaments – and you can’t do your job. It’s a shame! “
“He has to be fired on the spot. Get a new set of referees, these guys do not know how to do s ***. It’s a joke. Get rid of all the staff and start from the beginning. Everything. I will run sports. I could do “100 times better job. Marketing. Everything. Guys you have no idea. None. Guys you can not even rely properly.”
The side show continued between the games as Kyrgios mourned the voices of the crowd during the points before a set of high octane went right into the tie break.
With the stakes going up, Kyrgios bent down, hitting his racket on the floor as he was left behind with 3-1 in the break. The incessant monologue and swearing led Bernardes to impose a point penalty that led him to 6-3 and made a double error to give the set to his opponent. It was too much for Kyrgios not to let him go.
“I did not say anything,” Kyrgios screamed angrily at a critical moment to be penalized. “What’s unsportsmanlike about this…?” he asked repeatedly.
“I was talking to my friend; get me one now!”
“Just play,” the referee replied, trying to resolve the situation.
Kyrgios returned to his chair and constantly hit his racket in his bag, leaving Bernardes with no alternative but to impose a penalty that cost him his serve right at the beginning of the second set.
Sinner established himself properly, showing real maturity and order as he pushed the theatricals to the opposite end of the field to one side to lead 4-2, leading to the business end of the set.
Kyrgios tried to raise the ante late in the day, but Sinner broke again to close the place in the last eight after one hour and 39 unforgettable minutes.
Sinner will then face either Frances Tiafoe or Francisco Cerundolo.
