i think it is because she hasn't done much the last couple of months plus she's not in the form she was at the start of the year so people don't see her as much of a threat now. i'm so proud of her, i thought she was going to be in and out of the top 50 and top 100 all her career but this year she has stayed around the 30's and 40's and yes all she will do is improve and go up the ranks even higher.
