Her worst match from this year is certainly against Stosur. Too many unforced errors and Stosur came easily back from 5-1. This match is a lot different then yesterday's match!
Very painful were the losses against Dementieva, Indian Wells and Chakvetadze, San Diego.
That are only a few, but I can't think of any other real bad result/match.
If you're talking about victories, the list is a lot bigger!
