If Venus wins this, she's through to the semis. Sharapova hasn't played anyone in the top 50 since she lost to Kuznetsova in China. She's collected some lower tier tourneys, but as Venus (hopefully) progresses through the tourney, she should get better. I'm really looking forward to Venus v. Golovin!
Career Grand Slam in your 20s? Been there done that. Career golden slam your 30s?
There's only 1. Serena.
