Yes, It's An All-Teen US Open Women's Final

Leylah Fernandez, 19, is playing in her first US Open final. Emma Raducanu, 18, is playing in her first US Open final. Welcome to the battle for the Teen Tennis Title.

Except most everyone else in the tournament isn't a teen. So Fernandez and Raducanu were able to beat the odds -- and everyone else who was deemed a favorite -- to set up their historic match.

"It's magical," Fernandez told reporters after upsetting her third top-five ranked opponent, Aryna Sabalenka, on Friday.

"Honestly, I can't believe it," Raducanu later said, after advancing herself with a win over Maria Sakkari. "A shock. Crazy. All of the above."

To put things in perspective, this is the first time two teenagers have met in the women's final since Serena Williams beat Martina Hingis in 1999. And since 2010, only three teenagers had even reached the women's quarterfinals at the US Open.

Now come Fernandez and Raducanu and their stunning runs. Something will have to give. And once it does, a teenager will be champion. For now, that's all we know, and that alone is pretty cool.
