Few athletes enjoyed the kind of breakout year that Coco Gauff had in 2019, becoming the youngest tennis player to win a title at just 15 years of age! Coco first exploded onto the scene when she received a wildcard draw at Wimbledon and ended up reaching the fourth round, an amazing feat for a high school sophomore on her summer break. Each of her matches was the most watched match in the US for that day, as fans watched her quickly jump up the rankings. Before her magical Wimbledon run, she had around 30K followers on Instagram. Now, the tennis sensation has over 610K+ and another 180K+ on Twitter, who follow the breakout star, winning matches wherever she goes.
