Kirill Prigoda shattered the world record to take 200-metre breaststroke gold on day three of the Short-Course World Swimming Championships, while there was a rare failure for Katinka Hosszu in Hangzhou.
Prigoda raised the roof in the first race of the evening session, dominating his rivals to set a new record mark of two minutes 0.16 seconds on Thursday.
The Russian took the title in style, bettering the previous quickest time of 2:00.44 set by Germany's Marco Koch two years ago.
Qin Haiyang took silver, with defending champion Koch having to settle for the third step on the podium.
