Sharapova defeated Bethanie Mattek 6-0, 6-3 , having established a 4-0 lead the day before. She followed up with a 6-1, 6-3 win over Alla Kudryavtseva, who upset her at Wimbledon two years ago and afterwards memorably said it was because she did not like Sharapova's outfit.
Sharapova will play Sesil Karatantcheva in the quarterfinals. The two first met on court as teenagers at Indian Wells in 2004, when the younger and still unknown Karatantcheva famously declared that she wanted to face Sharapova and "kick her a** off."
