Singpore favourite Yip Pin Xiu swam away from the rest of the pack to win the 50m Backstroke S3 in a time of 58.7. Silver went to Great Britain's Fran Williamson and Bronze was won by Jiangbo Xai.
Williamson won the third silver of the night when she finished behind world record holder Yip Pin Xiu in the 50m backstroke (S3), adding to her bronze from the 50m freestyle two nights ago.
The 23-year-old, who won bronze in Athens, said: "I enjoyed that. I definitely could have gone quicker but I felt powerful in the water. Overall I am happy. I hoped to come here and medal and I have come away with two."
