Kishane Thompson became the joint-ninth fastest man in history after running the 100m in 9.77 seconds to win at the Jamaican Olympic trials on Friday.
The 22-year-old, who had not raced at all this season before the trials, is in just his second season as a professional.
But his time means he is now the fourth fastest Jamaican in history, behind Usain Bolt, Yohan Blake and Asafa Powell.
“My coach instructed me just to run the first 60 metres, nothing more – after that, shut it down,” said Thompson.
