American swimmer Lilly King was not impressed with her Russian rival's semifinal postrace antics — and she made that apparent in the pool and after her own heat. When Yulia Efimova, the Russian swimmer, won her semifinal 100-meter breaststroke heat, she waved a finger implying she was No. 1. King swam in the following heat and posted a better time. After her race, King apparently mocked Efimova's gesture during the postrace interview by wagging her own finger.
Efimova has failed more than one drug test before this year's Olympics, but she was allowed to compete at the last minute. King, when questioned about Efimova, said, "You know, you're shaking your finger No. 1 and you've been caught for drug cheating. I'm just not, you know, a fan." But King later backed up her sass up by beating Efimova in the final by almost a full second, creating a new personal record and Olympic record with her time of 1:04.93. We're curious how this rivalry will play out through the rest of the games.
