It all comes down to Sunday at Beijing, where Mirra Andreeva faces Qinwen Zheng for the trophy. Mirra Andreeva has won 4 in a row and 8 of the last 10 overall. Qinwen Zheng is rolling — 4 straight wins, 8 of 10 in recent play.

On paper it's close: comparable ratings, comparable serve numbers, small margins everywhere. Zheng comes in off a compressed schedule. Little separates them; Andreeva gets the nod on the finest of margins.
