Poland's Kamil Stoch won gold in the men's normal hill ski jumping.
The 26-year-old produced a superb final jump to win his country's first medal of the Winter Olympics in Sochi.
He finished ahead of Peter Prevc of Slovenia, while Norway's Anders Bardal took the bronze medal.
Defending champion Simon Ammann, victorious in both individual titles in Vancouver four years ago, could only finish in 17th place as he sought a record fifth Winter Olympic title.
Japan's Noriaki Kasai, competing in a joint-record seventh Winter Games at the age of 41, was eighth.
Stoch's victory came with jumps of 105.5m and 103.5m for a total of 278 points.
"I feel like it's really not happened to me. Did this really happen?'' said Stoch. "It was a great first jump. I didn't know if I won but I knew the result would be good.'"
Prevc scored 265.3 points, ahead of Bardal's 264.1 points.
