It shows how important the Williams are to the tennis world if they need to statistics on who's beaten both of them. What has that got to do with it?
Is this a joke? Do you watch tennis? Serena is currently the best player of her generation and Venus just won Wimby this year... for anyone to beat both of them back to back would be huge... but for Ju to beat them both, especially Venus at this point, on a surface other than clay is amazing...
Ju and Rena are coming for your faves... and nobody escapes alive, I promise you!
One of the very few people walking the planet who's top 2 faves are Serena and Justine
