Austrian teenager Marita Kramer pulled off a stunning surprise victory at the International Ski Federation (FIS) Ski Jumping World Cup in Sapporo.

The 18-year-old secured a debut World Cup victory in just her 13th start. 

She registered 132.5 points with her first jump and 147.1 with her second for a total of 279.6 and the gold.

Kramer was mobbed by fellow competitors at Ōkurayama Ski Jump Stadium, as she came to rest after her second leap. 

"I still can't believe it - I didn't expect to win, but I had a good feeling at the hill," Kramer said. 

"For tomorrow I will try to repeat this. 

"It's my first time in Sapporo and I really enjoy jumping here."

Second place went to Norway's Maren Lundby, with a total of 275. 

Olympic champion Lundby had triumphed in the first two events of the season’s World Cup in Lillehammer, but failed to make the podium last month in Klingenthal, Germany. 

Eva Pinkelnig of Austria finished third with a total of 271.1.

Lundby leads the overall World Cup standings with 325 points, followed by the two Austrians Chiara Hoelzl (280) and Pinkelnig (209). 

Kramer is currently seventh (171).

Action concludes with a second jump competition tomorrow.
