Teenager Charles Calvert produced the best display of his fledgling career to claim the men's three-metre springboard title at the British Diving Championships in Sheffield.
The 18-year-old belied his junior status to surprise Beijing Olympian Ben Swain, 22, who was left to settle for second - 37.9 points behind his rival.
Calvert showed impressive composure and technique during the final, breaking 70 points in all but one of his six dives.
His impeccably-performed reverse two-and-a-half somersaults half-twist final dive not only sealed victory, but also snuck him seven points past the 1,200-point qualification criteria mark for July's World Championships in Rome.
"I knew it was possible (to reach the qualification criteria) on the last dive, but I just blocked it out and worried about the dive," he said.
"I was extremely nervous. My hands were shaking and I was going through a few breathing techniques I have been working on with my coach.
"I knew I could do it. The diving board is my house."
