They weren't supposed to be here, but we're glad they are. An Australian Open full of surprises has left us with a delightful final matchup between Li Na, who considered retirement last summer, and No. 20 seed Dominika Cibulkova.
The top three women's seeds have been vanquished, thanks to Agnieszka Radwanska's brilliant upset of No. 2 Victoria Azarenka on Wednesday, but those remaining are playing compelling tennis heading into the semifinals.
Eugenie Bouchard's legion of fans at the Australian Open cheered her on to a quarterfinal victory against Ana Ivanovic and likely will be plenty vocal when the Canadian teenager faces Li Na in the semifinals.
Although she won in straight sets against Alize Cornet to advance to the fourth round of the Australian Open, Maria Sharapova is far from playing her best tennis after missing the second half of 2013 with a shoulder injury.
