ADELAIDE (Reuters) -Australia’s young guns are threatening to make a serious splash at next month’s Olympic Games with teenager Kaylee McKeown proving herself the best in the world on a thrilling, record breaking day two of Australia’s swim-offs.

In the midst of great emotion, McKeown seemed to be the calmest person around as she booked her ticket to Tokyo at the South Australia Aquatic Centre by smashing the women’s 100m backstroke world record in 57.45 seconds.
