Noah Lyles defended his world 200m title in electric fashion in a second US sprint cleansweep on Thursday, while Shericka Jackson thwarted Jamaican teammate Shelly-Ann Fraser-Pryce’s bid for a sprint double in the women’s race. Close on the heels of Fred Kerley leading a 1-2-3 for Team USA in the men’s 100m, Lyles made no mistake over the longer sprint, racing home in 19.31 seconds in Eugene.
