They're probably talking about some other 41 year old with a hyphenated last name.
I glanced at the official draw on the WTA site and D-K was the last accepted entry. She must have been the first alternate and gotten in from Sharapova's withdrawal. I imagine they'll pull her out of the Q draw and replace her with ALT pretty soon.
I think I'm right. The top three alternates according to the list in this thread were Brianti, Arvidsson, and D-K, and they're all in the main draw.
