Lilly King secures golden win for clean athletes

A wagging finger. A stunning swim. And with that, a win for clean athletes everywhere in an Olympics where no one is sure the playing field is really level.

Yes, Lilly King is quite a swimmer. The gold medal hanging around her neck Monday night was evidence enough of that.

But the brash 19-year-old from Indiana was much more than that on an electric night at the Olympic pool, where she held off Russian Yulia Efimova in a 100m breaststroke showdown loaded with overtones of a new doping Cold War.
