it has to be out of venus, serena, jen, lindsay, monica and possbily stevenson (if she happens to be on she would be hard to beat) however to pick 4 well i would pick definately serena, lindsay and venus and then the 4th person would be between jen and monica but since monica hasnt comeback yet and jen has done better of the last 3 years i would pick jen for the 4th player.
