Lilly King, Yulia Efimova
 

Lilly King, a 19-year-old from Evansville, Indiana, just added some serious drama to Monday's final in the 100-meter breaststroke in Rio by calling out her Russian rival for two failed drug tests.

Yulia Efimova won the first semifinal Sunday. As King watched the result on TV, she wagged her finger in disapproval, like Babu Bhatt:


In her semifinal, King posted a time of 1:05.70, which bested Efimova's 1:05.72. NBC's Michele Tafoya then asked King exactly what sort of message she was sending to Efimova with the finger wag.

"You've been caught for drug-cheating," King said. "I'm just not a fan."

How about that for some fireworks?

Efimova, who won bronze in the 200 breaststroke in London, was one of seven Russians who were banned from the Olympics last month because of the doping scandal in Russia. The IOC later re-instated her.

But Efimova had tested positive for DHEA, an endogenous steroid hormone, which landed her a 16-month suspension, starting Oct. 31, 2013, and the stripping of two world records and five international medals.

In March, Efimova tested positive for meldonium, the same drug that has sidelined Maria Sharapova for two years. Meldonium, which increases the size of blood vessels to improve blood flow, was banned by the World Anti-Doping Agency starting Jan. 1, 2016. WADA says it needs to conduct further studies on meldonium, which means Efimova got a lot luckier than Sharapova and many other Russian athletes who were not permitted to come to Rio.

King and Efimova will race side by side Monday night, in lanes 4 and 5, respectively. That is, assuming WADA does not stop Efimova on her way to the blocks.
