Lithuanian sensation Ruta Meilutyte finished narrowly outside her own world record as she took 50m breaststroke gold at the World Junior Championships.
The Plymouth-based star swam a time of 29.86 seconds in her heat, 0.38 secs slower than the mark she set at the World Championships in Barcelona.
Meilutyte, 16, also took silver as part of Lithuania's mixed 4x100m relay team.
Ukraine's Viktoriya Solnceva secured the silver, trailing home nearly one-and-a-half seconds behind Meilutyte.
Britain's Sophie Taylor claimed the bronze in a time of 31.38.
Meilutyte had already set a Championship record of 30.04 in the semi-finals, but went quicker again in a dominant display in the final in Dubai.
On a productive second day of the championship, she also qualified for the final of the 100m freestyle in a time of 55.16.
Meilutyte won gold in the 100m breaststroke and silver in the 50m breaststroke at the World Championships in Barcelona earlier this year.
