Another sprint, another Jamaican

A changing of the guard in women's sprints doesn't mean a redrawing of the map.

The 100m Olympic gold medal is heading back to Jamaica, only this time in the hands of Elaine Thompson, the 24-year-old who took down the USA's best, to say nothing of her training partner, two-time defending champion Shelly-Ann Fraser-Pryce.

Thompson turned what was supposed to be one of the most competitive races on the Olympic program into a runaway on Saturday.
