LONDON (AFP) - Australia's world No. 144 Nick Kyrgios caused one of the greatest Wimbledon sensations on Tuesday, when he sent world No. 1 and 14-time Grand Slam title winner Rafael Nadal crashing to a shock defeat.

The 19-year-old Kyrgios, making his Wimbledon debut, clinched a fearless 7-6 (7-5), 5-7, 7-6 (7-5), 6-3 victory to become the first wild card in 10 years to make the quarter-finals at the All England Club.

He is also the first player ranked outside the top 100 to defeat a world No. 1 since Andrei Olhovskiy stunned Jim Courier in the Wimbledon third round in 1992.

It was a performance of brutal inventiveness and uninhibited bludgeoning from a man who had had to save nine match points in his second-round win against Richard Gasquet and his reward is a clash with Canada's Milos Raonic for a place in the semi-finals.
