Lamont Marcell Jacobs won a dramatic men's 100m gold medal after becoming the first ever Italian to qualify for the final of the prestigious event.
There was plenty of drama before the race even started when Great Britain's Zharnel Hughes left the blocks early and was disqualified.
He was previously disqualified in the Commonwealth Games and his awful luck followed him to Tokyo.
Channel 7 commentator Tamsyn Manou said: "He's clearly broken there. We had Prescod, the other Brit, who broke in the semi-final tonight and then there was a huge delay after that. This is a disaster."
Bruce McAvaney added: "It is a disaster. He moves way before that gun. It is a big occasion."
When the race finally got underway, Jacobs became the fastest man on the planet, crossing the line in a lightning time of 9.80 seconds
American Frank Kerley claimed second, while Canada's Andre De Grasse got the bronze.
Jacobs' victory took plenty of people by surprise.
