This video is pretty funny. We know Serena is devoid of almost any civility and manners. Any times she tries to act that way it looks fully contrived. Here we have a video of Osaka showing her Serena side.
I gotta say, as classless as Serena is.... she never dropped to this level in her press conferences.
And you'd never see a Japanese athlete do it like this.
This is an embarassment for the sport.
