The Associated Press Gold medalist Alex Ferreira of the U.S. celebrates in the men’s freestyle skiing halfpipe finals.

LIVIGNO, Italy — The next time you see a senior citizen barreling down the mountain, maybe doing a double-cork while he’s at it, don’t think twice. That might just be your neighborhood’s friendly new Olympic champion.

Alex Ferreira, the freeskier who occasionally dons prosthetics to look 80 and calls his alter ego “Hotdog Hans” when he’s not kicking butt in the halfpipe, added a gold medal Friday night to the silver and bronze he’d won at the last two games to “finish the rainbow,” as his mother said.

The 31-year-old, a longtime fixture on the slopes and in the schools and rec centers in Aspen, Colorado, also put America in the win column for the first time in two weeks of halfpipe, slopestyle and big air action at the Livigno Snow Park.

“I’m going to drink copious amounts of beer,” Ferreira said when asked how he would celebrate.

He’s fun like that. This was a popular victory all across the park, squeezed out of a tight, brutal, all-night battle with Estonia’s Henry Sildaru — who skis slopestyle and big air, too, just like Eileen Gu — and Canada’s Brendan Mackay.

Bedlam and tears broke out in the stands after Mackay laid down the night’s last run, a solid one, but came up 2.75 points short of Ferreira’s winning score: 93.75.

When the Canadian’s mark came up, Ferreira bent to one knee and flashed a smile that lit up the mountain.

“Best moment of my life,” he said.

Asked what the best thing about the new gold medalist was, Mackay said there was too much to list.

“But honestly, the biggest thing that stands out about Alex, is that he is just an incredibly nice guy,” he said.

Among those near the medal stand to congratulate Ferreira was two-time Olympic titlist David Wise, who made the trip despite not making the Olympic team. He was ranked eighth in the world in halfpipe this season — a true sign of how deep the American team runs.

American Hunter Hess opened the morning’s qualifying by landing a good run, then putting his thumb and forefinger in the shape of an “L,” in a nod to the eruption that occurred Feb. 8 when President Donald Trump called Hess a “total Loser,” in response to Hess’ saying “Just because I’m wearing the flag doesn’t mean I represent everything that’s going on in the U.S.”
