Though multiple big-name players won't appear in the men's final four of the 2014 Australian Open, this year's version of the Grand Slam tournament has certainly not disappointed. Three of the top four seeds were eliminated during the quarterfinal round including No. 2 Novak Djokovic, who suffered a thrilling 6-2, 4-6, 2-6, 6-3, 7-9 loss to No. 8 Stanislas Wawrinka. Wawrinka will now face Tomas Berdych in the semifinals after the No. 7 seed upended third-seeded David Ferrer 6-1, 6-4, 2-6, 6-4 in the quarters. While this semifinal match will certainly entertain the masses, the match-up pitting the top-ranked player in the world and one of the games greats will garner most of the attention.

Seventeen-time major champion Roger Federer ousted defending Wimbledon champion Andy Murray in four sets to advance to his 11th-career Australian Open semifinal. Winner of the event four times in his career -- including a three-set championship victory over Murray in 2010 -- the 32-year-old Switzerland native is now set to face No. 1 ranked and 2009 Australian Open champion Rafael Nadal. Nadal removed No. 22 Grigor Dimitrov in the quarters and following the four-set battle that included two tie-breaking frames, Rafa will now face a fully-confident Roger Federer in what could once again be another epic battle between the two.

“I'm back,” Federer said following his quarterfinal victory over Andy Murray. “It was a great game on many levels, not just physically … but mentally also. I'm explosive out there and I can get to balls. I'm not afraid to go to balls. Last year at times I couldn't do it, but what's important is that I can do it now. Rafa and I have had some epics over the years. I hope we can slug it out here in a couple of days and I'm looking forward to the match.”

While Nadal meets Federer and Wawrinka battles Berdych on the men's side, No. 4 Li Na takes on rising Canadian star Eugenie Bouchard in the first women's semifinal while Agnieska Radwanska meets Dominika Cibulkova in the second semi.
