Xtra Time Web Desk: Italy’s Lamont Marcell Jacobs stunned the world to win the 100m final at the Tokyo Olympics on Sunday. He clocked an European record of 9.80 seconds to win the title. American Fred Kerley took silver with a personal best 9.84 seconds while Canada's Andre de Grasse repeated his bronze winning performance of 2016 with a timing of 9.89 seconds.

Jacobs had fired a warning with a European record of 9.84 in the semi-finals to become the first Italian ever to make the final but in the most wide-open showdown for decades, he still seemed an outsider.

Jacobs got an explosive start and maintained his form for an incredible win.

Kerley, hoping to be the first American winner since Justin Gatlin in 2004, ran brilliantly for second, with De Grasse finishing fast in another lifetime best.
