Zheng Qinwen's Remarkable Comeback Against Iga Swiatek at the US Open

There are moments that make people stop in the middle of a match when an athlete has just experienced a shock of 0-5, and then slowly rebuild, game by game, to turn everything into a victory. This is the story of Zheng Qinwen in the recent US Open round of 16 match, when she came back to defeat Iga Swiatek - the former world No. 1 - with a score of 7-5, 6-3 on hard courts. Not a lucky win. But a series of comebacks built from patient observation, from the gaps between two points. Based on my experience watching matches over the years, what makes Zheng stand out is not speed or explosive technique, but her ability to control emotions when everything seems to collapse.
