I was at the game too, and she made far too many errors. She was down a break late in the set; got it back and it went to a tiebreak. She was down 4-1, but stormed back and had two serves at 5-4. She then faulted and was down set point. She then received probably the worst line call I have ever seen. It was clearly in, there is no doubt that ball was in. However it went against her and the game was virtually over.
I was greatly impressed by her backhand, it is a massive weapon. She should make some massive strides this year.
