Wawrinka stuns Rafael Nadal @ Aus Open final

Swiss sensation Stanislas Wawrinka has stunned the injury-affected world no.1 Rafael Nadal to win his first Grand Slam title at the Australian Open on Sunday.

The 8th seeded dominated through the first two sets and overcame the distraction of a back injury to Nadal, and then the loss of the third set, to take it 6-3, 6-2, 3-6, 6-3.

The top-seeded Spain bull seemed to strain his back early in the second set and left the court for a medical time-out but after surrendering the set, he returned to the court swinging to stun Wawrinka with an early break.

The Swiss won the first set, broke Nadal in the opening game of the second and held serve to take a 2-0 lead before Nadal suffered in pain and clutched at his back after playing a shot from the baseline midway through the next game.

Nadal successfully held serve to trail 2-1 but quickly left the court for a medical time-out.
By seeing this, Wawrinka argued with the chair umpire about the lack of disclosure over the injury.
