Australian teenager Nick Kyrgios caused a sensational upset as he beat world number one Rafael Nadal to reach the quarter-finals at Wimbledon.

The 19-year-old wild card's huge serve helped him to a 7-6 (7-5) 5-7 7-6 (7-5) 6-3 victory on his Centre Court debut, and he will play Milos Raonic next.

Ranked 144, Kyrgios is the first man outside the top 100 to beat a world number one at a Grand Slam since 1992.

Nadal has failed to make the last eight at Wimbledon since 2011.

"I was in a bit of a zone out there and didn't really notice the crowd," Kyrgios told BBC Sport. "I was struggling a little on return but I worked my way into it and I served really well throughout, so am very happy.

"You have to believe that you can win the match from the start and I definitely did. I am playing really well on grass."
