Lamont Jacobs grabs shock 100 metres gold for Italy & Simbine finishes 4th.
Italy’s Lamont Marcell Jacobs claimed a stunning victory to take the Olympic 100m title. Jacobs became the first man to win the 100m other than Usain Bolt since Justin Gatlin in 2004.
Jacobs, 26, timed a European record of 9.80 seconds, with American Fred Kerley taking silver in 9.84sec in one of the most understated major championship 100m races of recent times.
Canada's Andre de Grasse, a bronze medallist at the 2016 Rio Games, repeated the feat in 9.89sec.
Akani Simbine has come within 0.04 seconds of securing a bronze medal for South Africa as he finished in fourth position.
The athletes were introduced in a dramatic light show – the stadium floodlights were shut off and 12 projectors cast 3D images of the world, zooming in to the Tokyo skyline, and then the name of each sprinter.
The lights came back on, swiftly followed by a horrendous false start for Zharnel Hughes in lane four, the Anguilla-born Briton not even bothering to question his disqualification.
Dressed in light blue singlet and lycra shorts, the US-born Jacobs, in lane three, made a good start, held his nerve through the drive phase and powered through to the line.
Jacobs joyously ran into the arms of Italian teammate Gianmarco Tamberi, who had just shared gold in the men's high jump and was waiting at the finish line.
The race, run in stifling temperatures of 30 degrees Celsius (84 Fahrenheit), had a distinctly underwhelming build-up and feel to it as hot favourite Trayvon Bromell bombed out of the semifinals in which China's Su Bingtian and Jacobs unexpectedly set Asian and European records respectively.
The Tokyo Olympics are the first since Athens in 2004 to take place without Bolt, who went on to win three consecutive Olympic 100m titles in Beijing, London and Rio de Janeiro, as well as three straight 200m crowns.
And for the first time since the 2000 Sydney Games, there was no Jamaican in the final, Bolt's long-time former teammate Yohan Blake failing to qualify from his semifinal.
The field was instead filled with a raft of relatively unknown sprinters, with Jacobs' main claim to fame a European 60m indoor title earlier this year.
The 100m in Tokyo, and the circus around it, has arguably been a pale imitation of Bolt's glory years during which the charismatic Jamaican not only dominated the sprints but also captivated a truly global audience.
While the spectacle that Bolt brought to the blue riband event has been missing since his retirement in 2017, so also has been the emergence of a new generation of sprinting hopes.
Many have been lauded as the athlete to fill Bolt's spikes, but no one has yet lived up to the considerable weight of expectation.
Added to that, the 68 000-capacity Olympic Stadium in Tokyo had no cheering fans because of coronavirus restrictions in the Japanese capital.
Earlier in the day, Shaun Maswanganyi and Gift Leotlela weren't able to progress from the 100m semi-final heats with Leotlela seemingly injuring himself near the finishing line.
