Kazan: Japan`s Daiya Seto was delighted to retain his men`s 400m individual medley gold at the world swimming championships on Sunday.
Seto clocked four minutes, 08.50 seconds to claim gold with Hungary`s David Verraszto taking silver at 1.40sec back as Chase Kalisz of the United States earned bronze at 1.55.
"I overcame a lot to win this race, so I`m really satisfied and happy," said the 21-year-old Seto after defending his Barcelona 2013 title.
Seto said his failure to qualify from the semi-finals in the 200m IM, when Ryan Lochte of the USA went on to claim a fourth straight gold in the event, had motivated him to do better over the longer distance.
"I missed the final in the 200 IM and I couldn`t compete against Lochte so I wanted to show myself in this race," added Seto.
