Australia’s Nick Kyrgios has stunned top seed Roger Federer 6-7 (2-7) 7-6 (7-5) 7-6 (14-12) to knock the Swiss star out of the Madrid Open.
Federer saved five match points yesterday before driving a forehand cross-court wide.
The 20-year-old Kyrgios won on his sixth match point while saving three Federer match-winning chances in their second round clash, which lasted two hours and 37 minutes.
Kyrgios, who knocked Rafael Nadal out of Wimbledon last year, sent down 22 aces to Federer’s 15 and next faces John Isner of the United States.
“I couldn’t return his first serve, I had a horrible performance on return of serve,” said Federer.
“That made life difficult for me.
“I’m disappointed with how I played on returns, and that cost me the match.”
