Michael Zheng and Y. Bu meet in the round of 64 at US Open on Thursday. Michael Zheng has won 6 of the last 10. Y. Bu has won 6 of the last 10.

Neither the serve numbers nor the ratings separate these two by much, which is why our number stays close to even. Zheng comes in off a compressed schedule; Bu comes in off a compressed schedule. Little separates them; Zheng gets the nod on the finest of margins.
