Zheng Qinwen recovers from set down to oust Keys in New York

Qinwen Zheng lost the opening set 1-6 but turned the US Open third-round meeting with Madison Keys around, edging a second-set tiebreak before closing out 7-5 in the decider. The Chinese player landed only 49.4 percent of her first serves, yet she was punishing when she found the box, winning 79.5 percent of those points and 53.3 percent behind the second ball despite five double faults. Keys was the steadier server in terms of placement at 67 percent, with four aces and a single double fault, but her second delivery yielded just 40 percent of points. That fragility proved decisive, and Zheng advanced into the fourth round.
