I'm so torn. I want Serena to go through, to keep open the chance of a Serena-Maria final, but if she goes through injured and Azarenka beats her... I just don't want Azarenka to snatch her wig before Maria
But then if Azarenka beats Serena and Maria gets to the final and beats Azarenka, she becomes the No. 1 and enacts her revenge after last year's humiliation.
It's academic though: Sloane Stephens vs. Li Na final, calling it now.
