No. 3-ranked Novak Djokovic has beaten Tomas Berdych 6-1, 7-6 (5), 6-1 to set up an Australian Open semifinal against defending champion Roger Federer.

Djokovic won his only major here three years ago, when he beat Federer in the semifinals en route to the 2008 Australian title.

No. 2-ranked Federer advanced earlier when he beat Stanislas Wawrinka in straight sets in an all-Swiss quarterfinal.
