It is pretty sad how she had to retire.
She is such a smart player. I never seen someone know the court so well. She could be in an awkward position and hit a smart and extordinary shot! I for one, don't think she would have been banned from the WTA for using cocaine. It isn't a sport enhancing drug. It is more of a pleasure drug.
Oh well. If she did use the drug, I can see why she alway uses white colored racquets and always smiles.
