Alina Charaeva and Qinwen Zheng meet in the round of 16 at Beijing on Wednesday. Qinwen Zheng has won 6 of the last 10. Alina Charaeva has won 3 in a row and 6 of the last 10 overall.
The serve is where this match separates: Zheng has been winning 72.5% of first-serve points to Charaeva's 63.6%, and on hard that gap compounds fast. Zheng should have enough here, though Charaeva has the tools to make the scoreboard uncomfortable.
