“Incredible, I am really satisfied,” said Kristoffersen, who threw away his poles and fell on his back in celebration after crossing the finish line.
“It was really close, both runs,” Kristoffersen said. “First with Mario, then with Marcel and Felix. I have been watching these guys for years. I am a big fan of Marcel and have watched a lot of videos from him.”
Matt, who won the event in 2000 and 2008, straddled the third gate of his final run and failed to finish.
Hirscher closed the gap to Aksel Lund Svindal in the overall standings to 22 points, and extended his lead in the slalom standings. The Austrian has 420 points, while Neureuther and Kristoffersen share second with 370 each.
The Norwegian made his debut in the last couple of races in the 2011-12 season, earned his first podium in his 15th race by coming third in the Levi slalom last November, and had two more top-three finishes in Adelboden and Kitzbuehel this month.
His recent results saw him enter the elite group of seven slalom racers who get the best start numbers each race.
“Getting into the top-seven helps a lot, and today I got a good start number as well,” said Kristoffersen, who opened the race wearing bib No. 1.
Asked about the 19-year-old winner, Hirscher called him “an awesome ski racer with a brilliant technique.”
Clinching his first win just weeks before the Olympic slalom suddenly has Kristoffersen dreaming about an upset in Sochi as well.
