Beatrice Chepkoech was leading the steeplechase final at the word championships until a mishap of epic proportions.
In a wild final on Friday night, Chepkoech had to backtrack after missing the water jump, allowing US duo Emma Coburn and Courtney Frerichs to smash the African domination of the women's 3000m race.
Coburn clocked a slick winning time of 9min 2.58sec to finish ahead of Frerichs and defending world champ Hyvin Jepkemoi of Kenya.
After an injury-interrupted buildup, Aussie Genevieve LaCaze was 11th in 9:26.25 -- two spots worse than her result at last year's Rio Olympics.
"If I can't have the gold medal it's lovely to see girls I raced in college get it because I do believe I can be that good," the 28-year-old said.
"I've raced those girls for so many years and I've watched them progress.
"The girl that came second, Courtney, I beat her in the Olympic final last year and layer upon layer she's become a better athlete.
"That's what you do.
"If you stay uninterrupted and focus on your technique and your fitness and all the little things she just proved what you can do.
"It's so inspiring and I do hope that in the next 12-24 months I can do that and I believe I can."
African runners had claimed gold and silver in the women's steeplechase at each of the past three world championships.
