In her defense this is the first set she's lost this tournament. She's pretty much demolished her opponents in the first 3 rounds.
That is true but chances are, here she will go on to win the match as well. And I am guessing that will be the trend from this point on going forward.
I think it was last year when at one point she was asked after a match that most of her matches ended up going into the final set and if she had any comments. I don't remember her answers but I remember the question.
