Yuto Horigome won his second gold medal at X Games California in the men's skateboard street event on Sunday.
A day after winning street best trick, the Tokyo Olympic gold medalist scored 95.66 in street to become the first skater to win both disciplines at the same X Games since 2002.
Horigome scored 91.66 on his first of three runs, enough to win the title, but the 24-year-old bettered it with his flawless second run featuring harder tricks, including a high-difficulty sugarcane grind.
"I'm filled with joy," said Horigome, who now has five career X Games gold medals. "It was great to pull off the trick I was aiming to do."
Kelvin Hoefler of Brazil scored 90.66 for silver, and Ryan Decenzo of Canada took bronze with 88.00.
Following a surprisingly patchy start to his qualification campaign for the Paris Olympics, Horigome says he feels on track to defend his men's street crown next summer.
"I'm starting to get confidence," he said. "I'm looking to raise my level and first do my best to qualify for the Paris Games."
Fourteen-year-old Japanese Liz Akama won her second silver at the X Games, replicating her women's street result in the street best trick competition.
"I'm really happy as I didn't think I could win two medals here," said Akama, who finished behind American winner Mariah Duran and ahead of Australian bronze medalist Chloe Covell.
Twelve-year-old Mizuho Hasegawa claimed silver in the women's park event won by Arisa Trew of Australia, with Grace Marhoefer of the United States third.
"It was fun. I can't believe I came second. It feels like a dream," Hasegawa said.
