Titmus strikes gold again as world records tumble in Hangzhou
Ariarne Titmus, Katinka Hosszu and Ranomi Kromowidjojo all struck gold again on a dramatic fourth day at the Short-Course World Swimming Championships in Hangzhou.
Having already triumphed in the 200-metres freestyle, Australian teenager Titmus set a new world record as she won in the same discipline over 400m, finishing in a time of three minutes 53.92 seconds.
China's Wang Jianjiahe had previously set the fastest time over the distance in October but had to settle for silver in a high-class final, finishing ahead of compatriot Li Bingjie.
"I am a little bit in shock. I knew the Chinese girl would go out fast and I was worried she would have a little left in the tank at the end, but I held her off," Titmus told the media.
Hosszu, meanwhile, claimed her third gold in China by winning the 100m individual medley.
The Hungarian had already prevailed in the 200m fly and 400m individual medley, while she also finished fourth in Thursday's 200m backstroke final.
In the first individual final on Friday, Dutch swimmer Kromowidjojo added the 50m butterfly to add to her triumph in the 100m freestyle.
Kliment Kolesnikov of Russia triumphed in the men's 100m individual medley, holding off a strong challenge from Italian Marco Orsi to take gold in a world-record time of 50.63secs.
There was success for his compatriots Vladimir Morozov and Evgeny Rylov too, in the 50m freestyle and 50m backstroke respectively, with Shane Ryan's bronze in the latter event giving Ireland their first ever medal in the 25-year history of the championships.
The United States' relay team posted a world record in winning the men's 4x50m freestyle, while Brazil also set a new best time when taking victory in the men's 4x200m freestyle.
