Italy's Marcell Jacobs produced a stunning upset to win the men's 100m final at Tokyo 2020.

Marcell posted a personal-best time of 9.80 to end the 13-year reign of retired Jamaica legend Usain Bolt as 100m champion at the Olympic Games.

USA's Fred Kerley and Canada's Andre De Grasse - who finished third of at Rio 2016 - also ran personal bests of 9.84 and 9.89 to claim the silver and bronze medals respectively.

China's Su Bingtian set an Asian record as he qualified fastest in the semi-finals with a formidable time of 9.83, but he was unable to replicate his heroics in the final with a disappointing sixth-place finish.

USA's Ronnie Baker went into the final as favourite but finished fifth with a time of 9.95.

Baker's compatriot Trayvon Bromell was tipped for 100m glory ahead of the Olympic Games but his time of 10 seconds flat was not enough to progress from the second semi-final, which was won by Team GB's Zharnel Hughes with a time of 9.98.

But Hughes' hopes of gold in the final were over before they began due to a clear false start which saw him disqualified.

The other runner in the race, Nigeria's Enoch Obaloluwa Adegoke, appeared to suffer a muscle injury after the first 50 metres and did not finish.
