Stefanos Tsitsipas on Sunday stunned the defending champion Roger Federer 6-7, 7-6, 7-5, 7-6 in the men’s singles fourth round at the Australian Open 2019.
The Greek player became the youngest Australian Open quater-finalist since Nick Kyrgios in 2015.

Coming to the match, 37-year-old Federer had a set point in 10th game of the second for a 2-0 lead but Tsitsipas saved it with a service winner.
Federer has won the last two Australian titles and has six overall at Melbourne Park, a record he shares with top-ranked Novak Djokovic and Roy Emerson.
The 20-year-old Tsitsipas says “I’m the happiest person on earth right now.” His best previous run at a major ended in a fourth-round exit at Wimbledon last year.
He will next play Roberto Bautista Agut, who beat 2018 runner-up Marin Cilic in five sets to reach the quarterfinals for the first time.
