Stanislas Wawrinka beats Novak Djokovic in Australian Open

Stanislas Wawrinka ended the three-year reign of Australian Open champion Novak Djokovic with a stunning quarter-final victory.

The Swiss eighth seed won 2-6 6-4 6-2 3-6 9-7 to set up a semi-final against Tomas Berdych, and gain revenge for an epic five-set defeat by Djokovic in the fourth round last year.

It was the first loss for Djokovic under the guidance of new coach Boris Becker, and brings to an end a winning streak of 28 matches on tour - and 25 matches over three years in Melbourne.

"He's an amazing champion, he never gives up. I'm really, really happy," said 28-year-old Wawrinka.
