Zheng beats You 6-3 6-2 in US Open qualifying quarterfinals

Qinwen Zheng needed only two sets to move past compatriot Xiaodi You 6-3 6-2 in the US Open qualifying quarterfinals, controlling the all-Chinese meeting from the baseline and behind her delivery. Her first serve landed just 52.7 percent of the time, but it was close to untouchable when it did, winning 89.7 percent of those points along with seven aces. That gap decided the match: You made 61.8 percent of her first serves yet won only 55.9 percent behind them, and 42.9 percent on the second. Zheng's seven double faults never cost her a set.
