"I have barely done anything", Kyrgios, who fell victim to a virtuoso display from Roger Federer in the third round of the US Open in NY, said.
The most spectacular part? Who will come out on top?
Tied at 3 in the third set and serving for the game on Arthur Ashe Stadium, Kyrgios skimmed a cross-court drop shot just over the net at a sharp angle.
The Australian said the shot was nearly unreal as he is no stranger to trick shots of his own.
"I think if he breaks there he probably runs away and wins that first set", Federer said.
But the best from the match, a highlight that would be played over-and-over came in the third set.
Federer's tidy 6-4, 6-1, 7-5 win in the third round of the U.S. Open on Saturday was a clinic in expert tennis, and he beat Kyrgios at his own game. "But that's just how he plays".
Yet after Federer broke in the 10th game to snatch the opening set, the level of Kyrgios dipped alarmingly. Verdasco denied the accusation, and Murray responded in an Instagram caption: "I'm off to get a health check as apparently I've started imagining things". The way he behaves on court.
Down 4-6, 0-3 against Pierre-Hugues Herbert, Nick Kyrgios got an alleged "pep talk" from chair umpire Mohamed Lahyani.
But Federer escaped, breaking Kyrgios to pocket the first set and dominating the second.
Suarez, seeded 30th, will face either former US Open champion Maria Sharapova or former French Open victor Jelena Ostapenko, who capped the Saturday night action on Ashe. Federer then bested the tricky Benoit Paire 7-5 6-4 6-4, in a performance that was more workman-like than it was clinical.
Zverev, the 21-year-old sensation, who has lifted titles in Munich, Madrid and Washington this year and reached finals in Miami and Rome, fell 6-7 (1/7), 6-4, 6-1, 6-3 to veteran compatriot Philippe Kohlschreiber. Nadal leads the series 7-3. Federer would later break Kyrgios' service to win the first set on a backhand victor.
Djokovic could meet Federer in the quarterfinals.
Federer's reward was a very winnable-looking fourth-round match against another Australian - the less gifted but more focused John Millman.
"I could take a leaf out of his book", he said, "just the way he goes about things, his demeanor".
"It was a'Serena scream.' I don't try to do it". Asked what he would want other players to learn from the way he conducts himself on the court, Federer didn't flinch.
Federer also regarded his point as "a special one".
Those missed opportunities would cost Kyrgios dear a couple of games later.
But Courier has sensationally claimed the forehand victor isn't that hard to pull off.
Afterward, Kyrgios said he was frustrated about not capitalizing on his chances. "He loosened up straightaway after that".
"At the beginning it was hard to get any sort of rhythm but I enjoy playing against Nick, he always keeps you on the edge and it's quite entertaining also for the opponent". All the pressure was off him. "It was unbelievable", he said with a smile. "When he gets in front, there's not much you can do".
