American Christian Coleman set a championship record as he claimed gold over 60m at the World Indoor Athletics Championships in Birmingham.
The 21-year-old, who set a world record of 6.34 seconds in February, led from the start in the final, clocking 6.37.
He saw off China’s Su Bingtian (6.42), with USA’s Ronnie Baker third (6.44), but Britain’s CJ Ujah was disqualified for a false start in the semi-finals.
“I felt good out of the blocks. I knew I had to just stand up, finish through and get it.”
Expectations of Coleman grew markedly when he took a world record which had stood for almost 20 years from USA’s former Olympic 100m champion Maurice Greene just two weeks before the championships.
He rose to global prominence at last year’s outdoor World Championships, claiming silver in both the 4x100m relay and notably in the men’s 100m, behind compatriot Justin Gatlin.
Coleman knew he had the ability and he was consistent. Repeat, repeat, repeat in the rounds, that’s what he has done. There were no real issues in the final. He just has that quickness. It’s all about foot speed for him.
With world outdoor champion Sally Pearson eliminated at the semi-final stage, Harrison beat compatriot Christina Manning (7.79) into second, with Netherlands’ Nadine Visser (7.84) preventing a US sweep by beating Sharika Nelvis (7.86) into fourth.
A high-quality shot put final saw seven men break 21 metres, though none could live with the 22.31m effort produced by New Zealand’s outdoor world champion Tomas Walsh.
And Venezuela’s Yulimar Rojas proved another international favourite at Arena Birmingham, setting the best mark of 2018 to take the women’s triple jump with a 14.63m leap securing gold.
