Anna Kalinskaya and Shuai Zhang meet in the round of 64 at Wuhan on Tuesday. Anna Kalinskaya is 7-3 across recent matches. Shuai Zhang has won 4 of the last 10.

Kalinskaya's 63.4% behind the first serve (against 59.7% for Zhang) means break chances should be scarce in one direction. The edge belongs to Kalinskaya — real, but not the kind you take for granted at this level.
