Well, Anna, since she is a specialist doubles player, is the person I'd most like to see progress, but she and Naomi have the toughest of all the draws there, so think it's extremely unlikely they will. I agree that I would give Heather and Alice the best chance of success.
Laura+Coco and Naomi+Anna are both first up on their respective courts tomorrow. I think the former will win but don't hold out much hope for the latter...
