Shuai Zhang retired from her match with Amarissa Kiara Toth on Wednesday, after her opponent wiped away a mark on the clay that suggested some shocking umpiring.
A forehand from Zhang appeared to land on the inside tramline during her Hungarian Grand Prix match with Toth, but the umpire called the shot wide. As the camera zoomed in on the mark that Zhang’s shot had left, it seemed even clearer that the shot had landed comfortably on the line.
