American Noah Lyles took a quarter of a second off the world's best time to clinch victory in the rarely-run 150 metres at the Ostrava Golden Spike meeting in the Czech Republic on Tuesday.
Lyles, the Olympic 100m champion and four-times 200m world champion, clocked 14.67 seconds to better Jamaican Kishane Thompson's mark of 14.92 set earlier this year.
"It was about time," the 28-year-old said.
"This feeling - it's nothing new. It's very hard to get used to running from a staggered 150 start. We do it in practice, but that's without blocks. But all in all, I think that it was really good."
South Africa’s Sinesipho Dambile finished second in 14.78, while Australian teen sensation Gout Gout took third in 14.96.
