Another way to look at this is : will her injury let her survive 5 more matches? assuming she progresses a match at a time!..
IMHO I don't think she will get past Makarova....even though we love her... there is no denying she is an absolute mess right now ...mentally, physically, emotionally and tennis skills wise....
I don't think it is that bad, although I don't know how serious the injury is. I do think that she played well in 1st set and for a large part of the 2nd the day before yesterday,
if she wouldn't have messed up the end of the 2nd set, she would end it easily in two sets.
Her serve is working better (she hit hardly and more of 1st serves in), she got out of trouble thanks to her serve couple of times, although it was the serve which let her down, but I think that it's more about her head than about everything else. She's still scared of double faults and she doesn't believe in her self enough in tight moments, that's why she's making mistakes.
I think it'll be tough to beat Makarova and she will have to bring in her best tennis, but she certainly has a chance. But who knows how Makarova will play on Friday?
I think that nobody can say how it could end, I will wait for that match and will see what happens.
