Poland's Kamil Stoch wins his second jumping gold of the games

Kamil Stoch considers himself fortunate to have won his second gold medal of the Sochi Olympics, overcoming what he called a "tragic" final jump to claim a narrow victory over Japanese veteran Noriaki Kasai.

Still, the 26-year-old from Poland will take it, completing a sweep of the normal and large hills and becoming only the third jumper - after Simon Amman and Matti Nykanen - to win double jumping golds in the same Winter Games.

"I have weird thoughts at this moment. I'm thinking, 'Is it happening for real or is it a dream?'" he said.

"I'm not thinking about the fact that I'm third in history. It's a shock for me that I made it because of the jumps I did today. The second jump was tragic."

Stoch, who dedicated the win to his wife, Ewa, as a belated Valentine's Day wish, said he was lacking in confidence heading into the final.

"Today I was nervous all day from the morning to the end of the competition," he said. "I made some mistakes, but what the heck, I won the competition."

Kasai took silver while Peter Prevc, of Slovenia, who won silver in the normal hill, earned the bronze.

Jumping last in the first round after the trial round was cancelled because of fluctuating winds, Stoch jumped 139 metres and totalled 143.4 points to give him a three-point lead over Kasai, a margin the Japanese cut to 1.3 points after the final round.
