Prepare to be amazed: a 13-year-old swimmer is about to make history! Yu Zidi, a name you’ll want to remember, is set to become the youngest swimmer ever to rank in the global top 10 of an event by the end of the year. But here's where it gets even more astonishing: she’s already #2 in the 200-meter butterfly at just 13 years old. This isn’t her only feat—she’s also breaking Asian records and outperforming swimmers twice her age. And this is the part most people miss: her achievements are not just about ranking high; they’re about redefining what’s possible at such a young age.
Yu Zidi first grabbed headlines at the 2025 World Aquatics Championships when, at only 12 years old, she finished 4th in the women’s 200 butterfly, 200 IM, and 400 IM. She also became the youngest swimmer in the competition’s history to win a medal, taking home bronze in the 4×200 freestyle relay. Fast forward to the Chinese National Games, and she’s still making waves. With a time of 2:07.41 in the 200 IM, she shattered the Asian Record previously held by Ye Shiwen—a record set in 2012, before Yu was even born. This time would’ve earned her silver at the 2025 Worlds, and she currently ranks #2 globally, just behind world record holder Summer McIntosh.
Here’s the kicker: by the end of 2025, Yu Zidi will be just 13 years and 76 days old, making her the youngest swimmer since 2000 to finish the year in the world’s top 10. But she’s not stopping there—she’s likely to end the year as #2 in the 200 IM, 4th in the 400 IM, and 7th in the 200 butterfly. Talk about dominance!
Let’s dive into the numbers. The table below showcases the youngest female swimmers to reach world-ranking positions #1 through #100 since 2000. Spoiler alert: Yu Zidi’s name appears multiple times.

On the men’s side, the youngest swimmer to hold a world #1 ranking since 2000 is Michael Phelps, who achieved this in the 200 butterfly at just 16 years old in 2001. That same year, he won his first world title and became the youngest man to break a world record in a men’s event. Other standout swimmers include Wu Peng of China, who cracked the top 20 at 14 in 2001, and Daniel Gyurta of Hungary, who reached the top 100 at just 13 in 2002.
