Zhang retires in tears after opponent erases ball markReutersChina’s Zhang Shuai on Tuesday retired from her Hungarian Grand Prix match in tears after her local opponent Amarissa Toth erased a ball mark on the clay court following a disputed line call. The chair umpire then stepped down to take a look at the mark and confirmed the ball had landed outside the line. China’s Zhang Shuai looks toward the court during her first-round women’s singles match against Croatia’s Donna Vekic at Wimbledon in London on July 5. “Wait, wait, wait. Keep the mark,” Zhang yelled.
