The WTA is into SEX sells. Well, well, haven't they heard of market saturation.
The ATP has a product-tennis and it sells that product.
The WTA on the other is selling itself as a vehicle through which one can get to see the likes of Kournikova. Logically, if she is absent from the tournament , her fans will also be absent.
To be honest, I doubt if she could have saved the LA tournament.
