Sha’Carri Richardson storms to 100m gold in stunning redemption tale

• American beats Jackson and Fraser-Pryce from outside lane
• Britain's Dina Asher-Smith trails in disappointing eighth

Ever since Usain Bolt's retirement, track and field has been desperate for a way to reenter the sporting mainstream. Over 10.65 extraordinary seconds it finally hit the jackpot. It came in the form of the 23-year-old Sha'Carri Richardson, the most flamboyant, brilliant and controversial talent the sport has seen for years, who powered home from lane nine to win a thrilling first 100m world title.

No one has ever disputed the American's talent - or star power given she has 2.4 million Instagram followers. Two years ago she was one of the favourites for the Tokyo Olympics, only for her dreams to go up in smoke when she tested positive for marijuana at the US trials following the death of her mother. First she missed the Games. Then, for most of 2022, she went missing.
