Young Australiation tennis sensation Nick Kyrgios has claimed another major scalp with victory over world No. 2 Roger Federer in Madrid.

In addition to beating then-world No. 1 Rafael Nadal at Wimbledon last July, the 20-year old defied expectations to down the Swiss master at the Madrid Open with a stunning 6-7 (7-2) 7-6 (7-5) 7-6 (14-12) victory.

The weight of meeting one of his childhood heroes on court did not appear to bow Kyrgios, who beat the elder statesman, and one of the most successful players in the history of the sport, in just over two and a half hours.
