Swiss tennis player Stanislas Wawrinka beat Spain's Rafael Nadal on Sunday to win the Australian Open 2014.

Wawrinka beat the injured world champion 6-3, 6-2, 3-6, 6-3.

Nadal had continued his dominant streak over Roger Federer on Friday to reach the Australian Open final for the third time, setting up the championship decider against No. 8-seeded Wawrinka.

With his 23rd win in 33 matches against Federer, the 27-year-old Spaniard had set up an ideal chance to win a 14th Grand Slam title and to become the first man to win all four majors at least twice in the Open era.

Meanwhile, Wawrinka had backed up his upset of four-time champion Novak Djokovic by reaching his first Grand Slam final with a win over Tomas Berdych on Thursday.

Wawrinka had a dominating performance against Berdych, the 2010 Wimbledon finalist.

"I don't know what to say. I'm speechless," Wawrinka said following the match. "I didn't expect to make a final in a Grand Slam — tonight it's happening."

Wawrinka went into the final against Nadal as an underdog, having never beaten the Spaniard in their 12 previous meetings.

Sunday marked Wawrinka's first Grand Slam final. The win will raise his world ranking from eight to three.
