Rising tennis star Cori 'Coco' Gauff featured in Whistle Sports' 'No Days Off' docuseries

While many of her 14-year-old peers are navigating their freshman year of high school or playing "Fortnite" or finally launching an Instagram account, Cori "Coco" Gauff is traveling the globe and making a name for herself on the tennis scene.

The American teen is one of the most promising tennis stars in the world. She won the girls' doubles title at the US Open (with Caty McNally) last month and became the fifth-youngest junior girls singles champion at the French Open in June. The players younger than her to take home the title? Martina Hingis (twice), Jennifer Capriati and Gabriela Sabatini. So, yeah, she's in pretty good company.

In fact, she's already getting comparisons to some of the biggest names in the sport -- yes, of course, including Serena Williams -- and drawing some serious attention from fans and tennis insiders alike. She has even trained with Serena's longtime coach, Patrick Mouratoglou, twice.

Gauff's star continues to rise, and she is now featured in the latest episode of Whistle Sports' "No Days Off" docuseries, which spotlights bright young athletes and their extraordinary talents. Following the Florida native during practice sessions and time with her family, it's a fascinating look into what it takes to make it to the big time.
