I know they are playing doubles in Bronx 50k at the moment, and Ting managed to get into Main Draw because of her higher ranking but Tian Tian couldn't play qualifiers because she was still in LA playing JP Morgan Chase Open doubles Semi's with Ting and thus Sun is only playing in doubles, Ting in singles and doubles. I have yet to find any results for this tournament, sorry!
