When Fred Kerley was a young boy, sleeping on a pallet with 12 other kids in a single room in Texas, he would dream of travelling the world. Instead, on a night of impossible drama in Eugene, he conquered it.
In the final desperate strides of this world 100m final, Kerley instinctively stuck his chest out and thrust his arms back like an aerodynamic Superman. As he did so, his compatriots Marvin Bracy and Trayvon Bromell, were straining, flailing, losing form. In a blurred finish, the 6ft 3in Kerley somehow got up on the line to snatch gold in 9.86sec, with Bracy taking silver and Bromell bronze both in 9.88sec.
