With Azarenka, Maria Sharapova, Petra Kvitova and Radwanska all in Saturday's semi-finals, this was the first time since Wimbledon in 2009 that the world's top four players had reached the last four at a WTA tournament.
This is the fifth time this year Azarenka has beaten Radwanska the hard-court in Sydney, the Australian Open, in Doha and at Indian Wells.
