Kaia never had more than one match point in a row and 4 out of 5 were on Kvitova's (very powerful and lefty) serve.
Well, but she was able to break Kvitova's serve twice and build a 4-0 lead in 3rd set, and later from 5-2 to 6-8. Total 5 match points missed.
BTW, our guys showed a good fight in DC doubles, lost first 2 sets, won the next 2, but then...from 5-2 to 7-9. It was so painful to follow the twitter updates. Chokestonia
