Australian teenager Nick Kyrgios fought back from match point down to overhaul Andreas Seppi in five sets and reach the Australian Open quarter-finals on Sunday.
The 53rd-ranked Kyrgios defeated the 46th-ranked Italian, who beat Roger Federer in the last round, 5-7, 4-6, 6-3, 7-6 (7/5) 8-6 and will play either Andy Murray or Grigor Dimitrov in the final eight.
Kyrgios fought off a match point at 5-6 in the fourth set and went on to force a tiebreaker before downing Seppi in a titanic fifth set in front of a charged home crowd on Hisense Arena.
It will be the second quarter-final inside a year for the 19-year-old after he reached the last eight at Wimbledon, becoming the first male teenager to reach multiple Grand Slam quarter-finals since Roger Federer in 2001.
Kyrgios staged a pulsating comeback and finished with 66 winners, 25 of them aces, and 74 unforced errors given his make-or-break playing style.
He broke Seppi's serve three times and lost his service three times.
Kyrgios said when he faced match point he thought back to his match with Frenchman Richard Gasquet at Wimbledon when he saved nine match points before going on to win.
"It feels so good," Kyrgios said. "This is my favourite court I've ever played on."
Kyrgios is a fast-rising star in the game and is the first Australian to reach the quarter-finals of his home Grand Slam since Lleyton Hewitt in 2005.
