Enigmatic Australian tennis player Nick Kyrgios stormed into the quarter-finals of the China Open in Beijing on Wednesday.
Despite a ropy start, the 22-year-old star saw off German serve-volleyer Mischa Zverev 3-6, 6-2, 6-2 in their second-round clash.
Kygrios smashed his racquet on the floor in anger, bending the head in half, when he conceded the opening set on Wednesday.
It was against Zverev at the Shanghai Masters in 2016 where Kygrios drew widespread condemnation for 'tanking'.
He was fined £13,535 for his behaviour during the 6-3, 6-1 loss but was delighted following his far superior performance in China this year.
“I just wanted to prove to myself how much I have improved,” the 22-year-old said.
“I knew it was going to be tough. He plays a very old-school type of tennis, likes to come forward a lot.”
“I got broken early in the first,” Kyrgios said after the match. "Then I kind of knew I had to loosen up and find my rhythm a little bit.”
Kyrgios next faces Steve Darcis — a fortnight after beating the Belgian in Davis Cup in Brussels — for a spot in the semi-finals.
His hilarious antics
Slouched in his chair, the entertaining young tennis pro was caught singing along during a changeover in Wednesday's win over Zverev.
A beautiful rendition of Taio Cruz's 'Dynamite'.
"Nothing really, just chilling out," Kyrgios, whose suspect temperament sometimes overshadows his talent, said afterwards when asked about his demeanour at times during the match.
Kyrgios was also spotted in a hilarious struggle with his bench at the end of the match.
More ridiculous antics
Somehow, he had managed to get his media accreditation pass stuck in the chair whilst the commentator watched on in disbelief.
"Only Nick Kyrgios could do that."
Grigor Dimitrov is due to face Juan Martin Del Potro later on Wednesday in what is being billed as the match of the round.
Meanwhile, US Open champ Rafael Nadal is back in action tomorrow when he faces Karen Khachanov.
