Ruslan Ternovoy secured hosts Russia’s third gold medal of the 2016 International Swimming Federation (FINA) World Junior Diving Championships after claiming the boys B three metres springboard crown at the Aquatics Palace in Kazan.
A score of 480.35 points proved enough to ensure top honours as China’s Yang Ling came second with 467.30 and Ukraine’s Nikita Kryvopyshyn finished third with 440.75.
Success for the Russian comes just a day after he had to settle for bronze in the boys B platform, an event which Yang won having led from start to finish.
Ternovoy set the right pace to the final, posting his best scoring dive - an inward two-and-a-half somersaults with tuck - in round one to earn 71.85 points and never looked back from there.
"I have never felt this before," he said.
"I am the world champion, which is great.
"I am very happy I have outscored the Chinese.
"I knew I was stronger than him yesterday, and now I have proved it by the result.
"My list of dives was not of the maximum difficulty, but it was important for me to perfectly execute them and earn high scores."
The day’s other final saw Germany’s Elena Wassen pip Great Britain’s Lois Toulson to the girls A platform title.
Just 0.30 points separated the pair with Wassen posting 430.70 and Toulson managing 430.40.
"It was really unexpected, and I am very happy that I won," the winner, whose scores never dipped below 56 points in the final having found herself in fourth place after the preliminaries, said.
"I actually can’t believe it."
Completing the podium was Canada’s Olivia Chamandy with a score of 429.80 points.
Action in Kazan is set to conclude tomorrow, with competition in the girls B three metres springboard and boys A platform taking centre stage.
China lead the medal standings with five golds and 10 overall.
Russia are second with their three golds, while Britain are third courtesy of their two titles.
