Salmon ran a personal best 54.10 seconds in the women’s race.

Shawn Rowe ran 50.08 seconds, Malik James-King- 50.15 seconds, Andre Clarke- 50.42 seconds and Marvin Williams-50.65 seconds, also qualified for the final.

Janieve Russell clocked 55.04 seconds, Andrenette Knight -54.55 seconds and Kimisha Chambers-56.03 seconds were also impressive.

Rushell Clayton, the bronze medalist from Doha in 2019, also did enough to advance, running 54.67 seconds.
