BELLA Pasquali and the Australian U20 mixed 4x400m team have conquered the world after winning gold Wednesday morning.

Qualifying fastest overnight in Lima, Peru, the Australians made up of Bella, Jordan Gilbert, Jack Deguara and Sophia Gregorevic dominated the field to smash their own U20 Oceanic record from their heat run, finishing in 3:19.27 in the final.

Running second, Bella was handed the baton from Gilbert in a tight opening to the race and was able to put a gap between the field as she reached the back straight, coming home in signature fashion to set up a lead Australia would never relinquish.

Fellow Victorian Gregorevic was tasked with the final leg of the race and held her nerves to come home with a comfortable win, as Poland (3:20.44) and China (3:21.27) took out the remaining podium positions.

It’s the first medal Australia has won at the championships following the conclusion of day one.
