TOKYO (Reuters) - Usain Bolt has gone but there looks to be a more than worthy heir to the crown in the shape of 17-year-old Erriyon Knighton, who qualified for the Olympic 200 metres final with the sort of nonchalant ease that would have made the great Jamaican smile.

The American has taken Bolt's Under-20 world record and though he clocked a relatively pedestrian 20.02 seconds to win the first semi-final on Tuesday, he was glancing at his rivals as he passed them, having been behind coming off the bend.
