Impossible to pick just one match today, so there are three picks that need to be made.
The first women's semi is Kim Clijsters and Victoria Azarenka.
The second women's semi will feature Maria Sharapova and Petra Kvitova.
I'll go against my first instincts and take Azarenka in the first match and then hve to go with Kvitova in the second. Both matches could be classics.
The men's match is a classic before it is even played.
What more can you say about Federer vs Nadal?
Even though Nadal leads the career series 17-9, it's hard not to like the way Federer is playing. Let's go with Fed in 4 great sets even though it's hard to not pick Nadal.
Should be a great night of tennis.
