Mary Carrillo commented that she had heard that Venus was suffering from shoulder pains prior to the match. Venus wasn't showing any grimaces or any sign of pain, accept for her erratic play, which Mary said could have to do with her shoulder injury.
With Venus down 0-2 in the first set, Mary said that Venus could pull out. Why she said this, I don't know. Perhaps she was overestimating Venus' injury or will to play, but Venus won the set...lost the second, but won the third set pretty easily 6-2.
Seriously, though, Venus was not playing that great. She has Evie, who made major mistakes on major points, to thank for the victory. She will have to cut down on those errors in the next rounds.
