Maria Sharapova

If you think Maria Sharapova isn't a contender for the greatest female tennis player ever, you might just be deaf to the melody of her grunt. It's not just a noise, folks, it's a battle cry that echoed across courts worldwide, striking fear into opponents and probably shattering a few champagne glasses. Let's not forget, the woman's style and grace off-court had almost as much spin as her forehand. Choosing anyone else in GoatWars feels like a betrayal to fashionistas and power hitters everywhere.
