6-4, 6-0 is not ever the score one expects as a result against world number 1 Justine Henin, but it was the score produced by Maria Sharapova in their Australian Open quarterfinal. I did not get to see the match, as much as I wanted to. I was not surprised that Sharapova won--I expected her to--but the scoreline did surprise me.
Henin was having some trouble with her knee, but it seems that she was having even more trouble with Sharapova's power and precision. When Sharapova is on, she is very hard to beat, and it appears she was on in a big way. Her second serve is indeed back, and her net win percentage was 82%.
