Nicole Turner has finished fourth in her heat of the women's 200m individual medley and her time of 3.17.09 was good enough to earn a place in the final.
The swimmer has now qualified for her third final in as many events, an impressive achievement given that she is still only 14-years-old.
“I was really happy with that swim,” Turner said afterwards.
