Italy's Lamont Marcell Jacobs won the men's 100-meter dash at the Tokyo Games on Sunday, crossing in 9.80 seconds to become his country's first-ever Olympic champion over the distance.
The performance capped off a golden night for Italy at the National Stadium, with Gianmarco Tamberi sharing gold in the men's high jump final just moments before the running of the blue ribbon race.
American Fred Kerley finished 0.04 behind Jacobs for silver, with Canadian Andre de Grasse a further 0.05 back for bronze.
After qualifying third from the semifinals in 9.84, the 26-year-old Jacobs stepped up to claim the sprint throne left vacant by Jamaican great Usain Bolt, winner of the event at the previous three games.
Jacobs, who was born in Texas and raised in Italy, was in disbelief after winning the race in a new European record time.
"I don't know, it's a dream," he said. "Maybe tomorrow I can imagine what they are saying, but today it is incredible."
"It was my childhood dream to win an Olympics Games and obviously a dream can turn into something different, but to run this final and win it is a dream come true."
It was the first time since 2004 that a Jamaican has not won the event, with London 2012 runner-up and two-time relay gold medalist Yohan Blake failing to advance to the final after finishing sixth in his semi.
China's Su Bingtian finished sixth in 9.98 after qualifying equal fastest for the final with an Asian record time of 9.83.
The three Japanese entrants -- Ryota Yamagata, Yuki Koike and Shuhei Tada -- had fallen short of reaching the semifinals on Saturday.
Tamberi tied with Qatar's Mutaz Essa Barshim after jumping 2.37 meters in the high jump final. Barshim and Tamberi ended up with equal highest jumps after three misses each at 2.39 m and chose to share the gold rather than go into a jump-off to decide a sole winner.
Maksim Nedasekau took bronze for Belarus, while Japan's Naoto Tobe finished 13th with a best jump of 2.24 m.
Tamberi, who missed the 2016 Rio de Janeiro Games due to injury, shared a warm embrace with Jacobs at the 100 m finish line.
"When I got to Gianmarco we support each other...being here together is something spectacular," Jacobs said.
Barshim is just the second-ever gold medalist from Qatar. Weightlifter Fares Ibrahim E H Elbakh won the country's first gold medal on Saturday in the men's 96-kg division.
In the women's triple jump final, Yulimar Rojas smashed the world record to win Venezuela's first gold medal of the games.
Rojas flew 15.67 m to improve the previous world record by 0.17. Portugal's Patricia Mamona jumped 15.01 to take silver, a 0.14 m longer leap than bronze medalist Ana Peleteiro of Spain.
China's Gong Lijiao won women's shot put gold, recording a personal best of 20.58 m to finish ahead of American Raven Saunders and Valerie Adams of New Zealand.
The 36-year-old Adams reached the podium for a fourth straight games, having won gold back-to-back in 2008 and 2012 before taking silver in 2016.
In the women's 100 hurdles, Japan's Asuka Terada was unable to advance to the final after running sixth in her semi with a time of 13.06.
Jasmine Camacho-Quinn of Puerto Rico set an Olympic record of 12.16 in winning her heat.
