The 4x100 meter relay is one of the most thrilling events in track and field, but because it requires precision for blind baton handoffs, you never quite know how races will shake out.
It was no different on Saturday night in Eugene, Oregon.
The men's and women's 4x100 medal races were held at the World Athletics Championships, and neither favorite won gold, instead taking silver.
In the women's race, the United States earned a surprise win, with Twanisha "TeeTee" Terry holding off Jamaica's Shericka Jackson down the final straightaway for a title-winning time of 41.
