SMU alumna and five-gold Paralympic champion Yip Pin Xiu rewrote the world record for the 200m freestyle S2 classification twice in eight hours at the Australian Short Course Championships yesterday. The world record had stood for 15 years, in part because races are more commonly held in the long-course format. Besides, this event for the S2 category is not contested at the Paralympics and has not been held at the world championships since 2010. The world record is the 30-year-old Singaporean's latest, and adds her leading times in the S2 50m and 100m backstroke (long course) events. Pin Xiu said the meet gave her the chance to review and create short-course strategies, such as more efficient turns, and being able to break the world record is an icing on the cake. She also shared that she has three more events coming up and would be looking forward to producing more good timings and racing well.
