Zheng Qinwen erases another 5-0 deficit to stun Iga Swiatek and reach US Open quarter-finals
The most important takeaway from the US Open is simple: do not, by any means, lead 5-0 against Zheng Qinwen. No scoreline is as hazardous. On Friday, the former Australian Open champion Madison Keys learned this lesson the hard way as she led Zheng 5-0 in the final set of an intense tussle before Zheng, the Olympic gold medallist, rolled through seven consecutive games to win the match.
