Olympic champion Jasmine Camacho-Quinn and reigning Wanda Diamond League champion Tobi Amusan are set to go head to head once again in a clash of the 100m hurdles titans at the sixth leg of the season in Lausanne on June 30.

Amusan and Camacho-Quinn vied for supremacy in the women’s 100m hurdles last season, and Lausanne promises to be the next chapter in a thrilling rivalry.

Nigeria’s Amusan is the reigning world champion and world record holder, having clocked 12.12 at the World Athletics Championships in Oregon last year. She later went on to win the Diamond Trophy, picking up her second Diamond League title in as many years.

Camacho-Quinn, meanwhile, was the most consistent winner on the Diamond League circuit over the past two seasons, claiming six victories in nine races over the course of the season. That included a handful of victories over Amusan, including at last year’s Athletissima in Lausanne, where the Puerto Rican star clocked a meeting record of 12.34.

Amusan, meanwhile, delivered her standout performance in the Wanda Diamond League final, setting a meeting record of 12.29 to defend her title and frustrate Camacho-Quinn at the crucial moment.

Camacho-Quinn has already got points on the board in her bid to qualify for this year’s final, having won the 100m hurdles at the season opener in Doha last Friday.

The two stars will be joined by Switzerland’s Ditaji Kambundji and Finland’s Reetta Hurske.
