The Belarusian held his nerve on the final shoot to win the gold from Oleg Naumov (RUS) who had to settle for silver and Woongtae Jun (KOR) who recovered from a poor fence yesterday to grab bronze.
Kasyanik stated: "I did not come here with the gold in my mind but after my win in fencing I started to believe it. It was not a difficult competition for me, all came easy and I focused to give my best in each event. Its my last year in Youth A and it finished with my only medal won until now and it is gold. Now I believe in myself. I feel very good and tonight I will celebrate the victory together with all the athletes."
"It was a good competition and before combined I was determined to win the gold, I run as fast as I could but I missed e few shots and then I could not reach the leader. I am happy to stand on the podium and I will work hard for future victories" said a very proud Naumov.
Bronze medallist Jun said after the ceremony: "I was training and came to win a medal and I made it. My good combined brought the bronze medal. I am Youth A again next year and my plan is to go to Wuhan in China and win the gold! After this victory I believe more in my self."
The title was really won by Krill yesterday as he held his concentration yesterday for the world record long fencing session which he won. A 12th place in the pool meant he started 1st in the combined event which he has 24 hours to think about.
When the gun went off to start the combined event, he did not disappoint and took the once in the lifetime opportunity to become the best under 18 Pentathlete on the planet with precision shooting and strong running under pressure.
