SMU alumna and swimmer Yip Pin Xiu retained her women's S2 100m backstroke title with a dominant performance that earned her a fourth Paralympic gold medal yesterday. Pin Xiu's gold on the opening day of competition at the Tokyo Games allowed Team Singapore to kick-start their campaign on a high note. Such was her performance that it seemed like nothing had changed from the 2016 Rio Games, where Pin Xiu blew the competition out of the water, winning the event in a world record 2:07.09 – nearly 12sec ahead of silver medallist Feng Yazhu of China. Pin Xiu will now turn her focus to her next event – the 50m back – next Thursday, in which she is also the defending champion and world record holder.
