Karo is absolutely crushing her low-ranked opponents, as it should be. She has a good shot at taking out Cibulkova in the semifinal, I think.
Kris, on the other hand, was a little lucky to beat Babos (who choked from a break up in the third set). She actually played better vs. Vekic, but was horrible on the big points: 0/3 break points saved and 3/12 break points converted. She really outplayed Vekic (winning six more total points), but kept choking on the big points. When she finally broke back for 5-all in the third set, she promptly handed it back and Vekic easily served out the match. And I don't know why she stopped attacking Vekic's serve after the first set.
