Last night in Rio was marked by its fair share of controversy. The women’s 100m breaststroke featured the United States’ Lilly King matching up against Russia’s Yulia Efimova.

What made this matchup so special is the underlying doping issues that Russian athletes have been facing. Efimova was one of several Russian athletes that tested positive for banned substances and did not know until the previous day, prior to 100m breaststroke prelims that she would even be allowed to swim.

Min the semi final round King and Efimova swam in separate heats, but the challenge had been thrown down as Efimova swam to victory in semi final heat #1, waving the #1 sign with her finger afterward.

Moments later in semi final heat 2, King bested Efimova’s time by .01 seconds, and flashing her own #1 finger. This set up a much anticipat s final with the 2 swimmers right next to each other in the center of the pool.

As the 2 closed for home in the final, King out touched Efimova to take home the gold and set a new Olympic record in the process. Afterward, as if winning was not a big enough statement, King spoke to NBC’s Michelle Tafoya stating that you can still swim fast and set records if you are clean.
