BREAKING: Roger Federer Knocked-Out of Australian Open

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.
