American Olympic champion Masai Russell has broken Tobi Amusan’s world record in the women’s 100m hurdles at the Diamond League meeting in Zurich.
Russell clocked a stunning 12.09 seconds on Thursday, eclipsing Amusan’s previous world record of 12.12 seconds set at the 2022 World Championships in Eugene.
The 26-year-old dominated the race from the opening hurdles to claim a historic victory and lower her previous personal best of 12.14 seconds.
Amusan finished second in a season-best 12.23 seconds.
“Competing in a world record race is amazing,” Amusan said. “I came out here and I did my best and I am happy with this SB.”
