Elias Ymer and Yi Zhou meet in the round of 32 at Ningbo on Tuesday. Yi Zhou has won 6 of the last 10. Elias Ymer limps in on a 4-match losing skid, just 3 wins in 10.

Neither the serve numbers nor the ratings separate these two by much, which is why our number stays close to even. The edge belongs to Zhou — real, but not the kind you take for granted at this level.
