Bialik: For Rafa, the key is to survive and advance. He's getting more comfortable on grass. He started looking like a two-time champ in the last three sets Saturday -- and the grass is starting to look more like clay, with the baseline worn down to dirt. Despite his shaky start to each match, he looks to me like the favorite in his half of the draw. Since no one asked, I expect the finals to be Djokovic-Nadal and Sharapova-Radwanska. (Disclosure: not guaranteed and subject to frequent revision in second week.)
Isaacson: Rafa has done what Serena ultimately could not, failing to overcome a bad day and a hungry opponent. Where the No. 25 seed Alize Cornet was aggressive, Williams played uncharacteristically passive on too many occasions, and even the greatest champions can't get away with that.
