Dominic Thiem fought off Nick Kyrgios and a rowdy crowd to overturn a two-set deficit in a thrilling match and reach the Australian Open fourth round.
Austrian third seed Thiem weathered everything home favourite Kyrgios threw at him to prevail 4-6 4-6 6-3 6-4 6-4.
Kyrgios had his opportunities but his shot selection - and occasionally his temper - let him down.
The match finished 50 minutes before Melbourne Park closes its doors to fans as Victoria begins a five-day lockdown.
US Open champion Thiem will play Grigor Dimitrov of Bulgaria for a place in the quarter-finals.
This was a fitting way for the crowds, who have been so vocal for Kyrgios, to say goodbye to the tournament for now.
They were treated to the full range of Kyrgios' brilliant shots and lapses of concentration, as well as a hardy, gutsy performance from Thiem.
The two players shook hands and had a warm conversation at the net, before Thiem was given a standing ovation by the fans.
"A first match against Nick on his favourite court with an amazing crowd - there are easier things to do," Thiem joked afterwards.
"I was dealing with the loss already before somehow I fought back in."
It is the fourth time Thiem has come from two sets down to win at a Slam, which he memorably did to claim his first major title in New York in September.
