If you search for chubbyamsterdam on youtube there are several excellent Serena matches (and a few Venus ones too) and a recently uploaded one is the AO semi in 2005 with Sharapova.

I never actually got to see this match. The commentating by Mary Carillo is so annoying it's unbeleivable. Sharapova was still the jewel in the crown back then but Serena fought back.
