Emotional Fiona Doyle left to wonder

Doyle led the race for 150m but tied up in the last 50m to touch in 2:29.76. Argentina’s Julia Sebastian won the heat in 2:27.98.
After four heats, the 24-year-old Limerick swimmer placed 25th overall. She would have needed to break her Irish record of 2:27.63 by over a second to make the semi-finals (2:26.58).
