Brianna Rollins recorded the equal fourth fastest 100 metres hurdles ever run as she clocked a stunning 12.26 seconds at the U.S. world championship trials on Saturday at Des Moines, Iowa.
Finally catching an allowable wind, the 21-year-old U.S. collegiate record holder sent a strong message to Australian Olympic and world champion Sally Pearson with a dominant performance.
Only Bulgarian Yordanka Donkova, whose 1988 world record is 12.21 seconds, and compatriot Ginka Zagorcheva, the former record holder, have run faster.
"I just feel so overwhelmed, so emotional. It is so amazing," said Rollins, who previous best was 12.39 seconds at the U.S. collegiate championships.
The time, run with an aiding wind of 1.2 seconds, exceeded Pearson's 2011 world championship best of 12.28 seconds and Gail Devers' American national record of 12.33 seconds.
Can the recently turned professional break the world record?
"I don't know. We'll see," said Rollins, whose best before this season was 12.70 seconds.
Lured to athletics as a teenager "because someone told me I was fast," Rollins selected the hurdles "because I thought it was interesting and fun to do."
