American teenager Katie Ledecky on Saturday set her second world record at the 15th FINA world championships as she won the 800m freestyle. Ledecky, 16, who also won gold in the 400m and 1,500m freestyle events, as well as the 4x200m freestyle relay, finished first in 8:13.36 - 0.74 faster than the old mark set by Rebecca Adlington in Beijing in 2008 In a repeat of the 1,500m final, Dane Lotte Friis took silver, while the bronze went to New Zealand's Lauren Boyle. It was the third world record broken in the Palau Sant Jordi on Saturday and the sixth overall. 16-year-old Ruta Meilutyte set a new mark in the semi-finals of the women's 50m breaststroke, beating the mark Yuliya Efimova had set earlier Saturday in the heats. -- SPA 21:34 LOCAL TIME 18:34 GMT تغريد
