Defending champion Roger Federer is out of the Australian Open after Greek 14th seed Stefanos Tsitsipas earned the biggest win of his career to reach the quarter-finals.
The Swiss lost 6-7 (11-13) 7-6 (7-3) 7-5 7-6 (7-5) on a dramatic night.
Federer, a six-time champion, failed to reach the last eight in Melbourne for only the second time in 16 years.
20-year-old Tsitsipas saved all 12 of 37-year-old Federer’s break points on his way to a famous win.
Tsitsipas will play Spain’s Roberto Bautista Agut, who beat sixth seed Marin Cilic in five sets, in the first Grand Slam quarter-final of his career.
