Nick Kyrgios will face Dominic Thiem in the third round at the Australian Open after a fiery comeback victory over Ugo Humbert.
The outspoken home favourite dropped the opening set 5-7 against his French opponent in a typically eventful late-night clash at the John Cain Arena in Melbourne, after which he smashed his racket in frustration.
Kyrgios also ranted at the umpire, received a point penalty for his behaviour and lost his cool with his own team during the course of a match that lasted almost three and a half hours.
Kyrgios recovered his composure to take the second set 6-4, but he then found himself behind as world no34 Humbert battled back to take the third 6-3.
The Australian did not give up, however, saving two match points before going on to comfortably win the fourth-set tiebreak.

He eventually took the final set 6-4 to wrap up an exhausting five-set victory.
Kyrgios will now face Thiem, the 2020 US Open champion who was beaten by Novak Djokovic in the final in Melbourne last year.
"I don't how I did that, honestly, that is one of the craziest matches I've ever played," Kyrgios said after beating Humbert.
"It was a strange match, if you guys were inside my head, there were some dark thoughts in there.
"It's my career, I live to fight another day and hopefully I can continue to play tennis in front of you guys."
