Double Olympic champion Ye Shiwen also won a gold for Zhejiang Wednesday. The 17-year-old, who lost her form at the Barcelona Worlds and failed to win a medal in her trademark medley events, claimed the 400m medley gold in 4:31.59, which was the third fastest time this year and also her season best.

But CCTV broadcast showed the 400m medley world record holder looks extremely tired, out of breath, after the race and she had to lean on the wall before walking to the mixed zone for a CCTV interview.

"I expected to swim in 4:30, but I was too tired," said Ye, who finished seventh in the event at Barcelona. "I think I can be better in my following events."

Ye will also compete in the 200m medley and backstroke.

Also Wednesday, Zhejiang swimmer Wang Shun updated the national record in the men's 400m medley with 4:09.10, which was the third fastest time in the world this year. Yang Zhixian of Hunan also broke the national record in 4:10.78.

In the women's 4X100m free relay, Shanghai finished first in 3:36.55, while Liaoning and Beijing ranked the second and third.
