Before the last shot, Samuelsson was not even in the top 10, having shot two misses in the second round.
But after a full shooting, a fast lap and a monster sprint, he managed to take the gold ahead of the German Roman Rees.
- Coach Johannes Lucas shouted so much that I didn't dare miss the gold, says Samuelsson after the race.
Ponsiluoma also rode very well and managed to win the bronze despite four barriers in total.
This was Sebastian Samuelsson's third medal in the championship.
Yesterday he won gold at the same time as Peppe Femling won a silver, and on Friday the same duo won silver and bronze.
