Il Nuovo Postiglione - China's 13-year-old Yu cruises as Asian Games swimming begins

Yu became the youngest swimming world championships medallist in history last year when she won bronze as a 12-year-old as part of China's 4x200m freestyle relay team.

She also finished a whisker outside the medals in fourth in three world individual events.

She has embellished her growing reputation this year, notably with a victory over multiple American Olympic champion Regan Smith in March.

She opened her Asian Games campaign at the Tokyo Aquatics Centre by breezing through her women's 200m butterfly heat, qualifying for Sunday evening's final with the fastest time in 2min 7.97sec.

It was 2.7sec quicker than the second-fastest qualifier, Chinese compatriot Chang Mohan.

Yu does not turn 14 until October.

Pan was in action in the men's 100m freestyle, the event in which he won gold and set a world record at the Paris Olympics.

He qualified with quickest in 48.07sec, ahead of South Korea's Hwang Sun-woo.

"The first 50 I felt I controlled my speed and then the second 50 I was at the max," said the 22-year-old Pan.

"I think tonight I will be better."

Pan is looking to rebound from a disappointing world championships last year in Singapore, where he failed to make the final in either the 100m or 200m freestyle.

He said his stunning success in Paris had taken time to get used to.

"It's such a big change year by year, especially after Paris. The change is in my training and in my life," he said.

"I'm getting better at adjusting year by year."

Japan's Tomoyuki Matsushita finished fastest in the men's 200m individual medley with a time of 1min 58.56sec.

Japan are looking for better results in the pool after winning only five golds and finishing a distant third in the swimming medals table at the 2023 Asian Games in Hangzhou.

"This is being held in Japan and although there's no pressure, I want to show my best to all the people here," said Matsushita.
