Yeah, I don't know. I was really disappointed after that match and loss lots of vcash too!
She just can't sustain highlevel play these days, especially against top players and as you say hungry, "nothing to lose" youngsters. Look at all her matches post Wimbledon and the pattern is there:
Kim Stanford F (brilliant save against Patty, collapse against Kim in next round)
Kim Open QF (on her racket, up a set and break, collapse final set)
Pironkova 1st round (brilliant first set, collapse second set)
Sveta German Open QF (brilliant save against Hingis, collapse next round)
Martina (brilliant first set bagel, collapse)
Vaidsova (brilliant first set save, collapse)
So sad. I hope her game clicks at Wimbledon, otherwise she'll lose lots of points.
