“I’m just proud, in the second run I just wanted to be brave, ski on the limit. I think it was about time that I got a win.”
Robinson has 300 points in the giant slalom standings, just four more than Sara Hector who crashed out at the exact same point as Brignone, early in the second run.
Sweden’s Hector and Brignone had shared the wins from this season’s four previous giant slalom races and the Italian had a big advantage before beginning her second run.
Brignone is the oldest woman to win a World Cup race at 34 years old and is gunning for her second overall title with four wins this season.
She was favourite for a second straight victory after winning Sunday’s super-G in Cortina d’Ampezzo and a fine first run on Tuesday morning.
An “exhausted” Brignone was furious with her errors on her home snow.
“I’m angry and disappointed because in the giant slalom I’m skiing really good and I’m making mistakes,” she said.
“It’s the third race out of five that I’m out and this is kind of making me crazy.
“I wanted to win today in front of my fans, my family, my friends.”
Her mistake cost her top spot in the giant slalom standings and led to her lead in the overall table being slashed to 55 points, with Gut-Behrami lurking in second ahead of downhill and super-G events in Garmisch-Partenkirchen, Germany this weekend.
Gut-Behrami achieved her first giant slalom podium of the season after five podiums in super-G and downhill this campaign.
“It was a little bit of a complicated start to the season for me in GS, physically,” the Swiss skier said.
“I’ve had some trouble with my knee and I’m not one who can ski when I feel pain so first of all I had to find my confidence again to wake up every morning and say ‘OK, nothing is hurting’.
“I’m still doing a few mistakes, it’s still not perfect but I’m fast and on those results I can build and get some confidence.”
