China’s Zheng Qinwen shook off slow starts in the opening two rounds of the US Open and took down unseeded German Jule Niemeier 6-2 6-1 at the US Open on Friday.
The Olympic gold medalist and 7th seed fired off eight aces and seized five break points on the Grandstand hard court in her first straight-sets victory of the year’s final major.
Niemeier, nursing a foot injury, committed five double faults and held serve in just three games of the match that wrapped up quickly in an hour and 21 minutes.
