Donna is now most likely in Australian Open MD as Putintseva failed to win in Dubai and is not playing Ankara. I would expect Elina to overtake her in Ankara in a fortnight and probably Puig, but if Birnerova doesn't make the final, she will be in unless no one withdraws
EDIT: Putintseva made MD as she climbed higher than I thought. Now only 2 of Svitolina, Puig and Birnerova have to do well to push her out
