Three swimmers became spotlight of the night in Duna Arena as they managed to renew the world records.

Britain's Adam Peaty improved his own 50m breaststroke record to 25.95 in the semifinals, from 26.10 he created in the heats on Tuesday morning.

"It was not really in my radar to swim below 26 seconds but I felt good tonight. Let's see what comes out tomorrow," commented Peaty.

China's Yan Zibei failed to secure a final berth with his 15th position in the semifinals.

With a new world record of 58.10 seconds, Canadian swimmer Kylie Masse met little challenge en route to becoming women's 100m backstroke world champion.

Olympic champion Lilly King also beat women's 100m breaststroke world record by 0.22 in 1:4.13. Chinese swimmer Shi Jinglin didn't finish on podium ranking 5th.

American female swimming star Katie Ledecky won her third gold in Budapest with her 1500m freestyle triumph at 15:31.82. Hou Yawen of China ranked fifth among eight finalists.

Ledecky also led women's 200m freestyle semifinalists, while China's 15-year-old swimmers Ai Yanhan and Li Bingjie missed the final.
