The United States extended its podium streak in the event to six Games with Fred Kerley's silver - after he placed only third at the U.S. trials.

Former 400 metres specialist (ranked #8 of all time) USA's Fred Kerley won the first semi-final, with defending bronze medalist Andre De Grasse from Canada qualifying as second.

In the third semi-final China's Su Bingtian got a blistering start and held off the group to improve his own Asian record by 0.08 to 9.83, concurrently setting the unofficial 60 metres world best.

Italy's Marcell Jacobs, who had arrived at the event as the 60 metres world leader, came in a close third and was timed at 9.84, setting the European record, improving his PB by 0.1 and equalling 1996 champion Donovan Bailey for #14.

[4] The center lanes of the final included the three heat winners Su, Kerley and Hughes and fastest second Baker.

Hughes bolted early for a clear false start, with all runners except Jacobs sprinting from the blocks after him, and was disqualified.

[5] From there, Jacobs opened up space on the group, with Kerley staying the closest as Adegoke pulled up lame, while De Grasse, after running last, accelerated and passed Baker and Simbine at the 90 metres mark to take his second bronze medal in the event.

Jacobs had the clear win over Kerley and was immediately cheered by Gianmarco Tamberi, who had just won the high jump event just 13 minutes earlier.

The Democratic Republic of the Congo, Nauru, the Refugee Olympic Team, Slovakia, and Tajikistan each made their men's 100 metres debut.
