Ana should move to R4 in two sets, if her statistics from match with Radwanska repeats vs Kuznetsova. Her 1st and 2nd service points won were excellent. Svetlana is a good match up for Ana, as Cajka said. If Ana plays good, she should win in two sets.
I am so happy she finally beat one of the sisters. Next time let's beat Agnieszka too.
