Australia's Iona Anderson has powered to silver in the women's 100m backstroke at the World Aquatics Championships in Doha, finishing second in a teenage rampage led by America's Claire Curzan.
The 18-year-old West Australian was joined in the final on Tuesday by Queenslander Jaclyn Barclay - a year her junior at 17.
Anderson set a personal best, touching at 59.12 seconds behind a dominant Curzan (58.29), who is only 19 herself.
