Sharapova through to quarters in French

Watched the Sharapova - Stosur match live today.  Samantha looked great and Maria looked very tentative early, and Stosur took the first set 6-3.   It was fairly even after a couple of breaks in the 2nd, and then all of a sudden Stosur's level dropped and Sharapova recognized it.  She turned on the pressure and took the 2nd set 6-4, and then dominated a fading Stosur to take the match with a 6-0 final set.

So, with the household names Muguruza, Suarez Navarro, and Bouchard (Canadian!) the other three in the quarters on her side of the draw, she and we will have to wait until tomorrow if the seeds on the other side get through.  Since I picked Halep as a dark horse, will she be able to take out Sloane Stephens?  And will Jankovic or the Energizer bunny on clay, Errani, emerge from that high-seeds match?

(Muguruza is from Spain, and Spaniards know how to play on clay. Sharapova should be wary.)

On the men's side, Djokovic and Murray advanced, and Federer didn't.  Too soon to say he's done, but I don't expect him to do well on clay any longer.
