This young lady continues to be a mystery to me.
She went out in the first round of the US Open and was so down afterwards it was awful to watch the press conference. The main diagnosis was that she wasn't properly match sharp. She had chosen not to play for three weeks beforehand on the US tour, but instead went back to the UK to practice.
I have noticed before that if she plays too many tournaments in a row she seems to get mentally exhausted and then just capitulates like she did earlier this year in Bahrain and Madrid. She has said herself that she needs to manage her schedule and can't see herself playing every tournament. Despite her amazing skills, maybe she just isn't up to it mentally. She seems to want to just play the Slams and the other really big tournaments.
