Chinas Yu Zidi has already burst onto the swimming scene, but the 12-year-old made more history at the 2025 World Aquatics Championships on Thursday.

Yu became the youngest ever medalist at the competition after being part of Chinas bronze medal winning team in the 4x200-meter freestyle relay in Singapore.

Although she did not compete in Thursdays final, Yu was eligible for a medal as she swam in the preliminary race to qualify her country for the final.

Australias team of Lani Pallister, Jamie Perkins, Brittany Castelluzzo and Mollie OCallaghan won gold in a time of 7:39.35 , with the US earning silver in 7:40.01 and China finishing almost three seconds after the Americans in third in 7:42.99.

Yu had narrowly missed out on an individual medal in the womens 200m butterfly earlier on Thursday after finishing fourth, 0.31 seconds behind third-placed Elizabeth Dekkers of Australia.

She also finished fourth and just outside a medal position in the womens 200m medley on Monday, touching the wall 0.06 seconds behind bronze winner Mary-Sophie Harvey of Canada.

She will have one more opportunity to win an individual medal at the 2025 World Aquatics Championships when she competes in the womens 400m medley, with both the heats and the final on Sunday.

Yus participation in the World Aquatics Championships has led to questions over the competitions eligibility rules. Swimming governing body World Aquatics has a minimum age requirement of 14 for the world championships, but Yus times are so fast that she qualifies regardless.

Brent Nowicki, the executive director of World Aquatics, admitted during the championships that the governing body will have to review its guidelines in the future.

I didnt think Id have this conversation, but now I think we have to go back and say, Is this appropriate? Nowicki told reporters in Singapore, per the Associated Press . Is this really the right way to go forward and do we need to do other things? Put other guardrails up? Do we allow it under certain conditions? I dont know the answer.
