Serena Williams versus:

Sharapova     19 - 2
Clijsters            7 - 2
Davenport     10 - 4
Henin                8 -6

So only the latter came close to matching up to the power that is Serena Williams.

Oh, and while on the topic of modelling etc, do check out the commercial record of Sharapova. Is there anything she won't plug?
