JINAN - Still fresh from the Gwangju worlds, China's Liu Xiang and Yan Zibei snatched a gold medal each at the FINA Swimming World Cup Jinan leg here on Thursday.

Liu, who failed to make the women's 50m freestyle final at the worlds, broke the World Cup record to win the 50m backstroke in 27.35 seconds. China's Chen Jie came second in 27.88, while veteran Emily Seebohm of Australia, winner of the event in Tokyo, took third in 27.99.

"I performed my normal level," Liu said. "I swam 50m free at the World Championships, so this time I chose to swim 50m back and 50m fly."

China's Yan Zibei won the men's 100m breast in 59.08. Andrew Wilson of the United States and Wang Lizhuo of China both ranked second in 59.56.

In the women's 400m free, Erica Sullivan from the United States came from behind to win the race in 4:08.70. China's Bi Wenxin trailed in 4:10.23, while China's Dong Jie ranked third in 4:11.32.

Sullivan said: "It was hard. I definitely tried to go out fast. I felt good and really controlled so I decided to keep going. I focused on myself in the race."

"The World Cup is totally new for me. It is my first time come to China and I love the Jinan city very much," she added.

Danas Rapsys of Lithuania led all the way to win the men's 400m free in 3:43.91, breaking his own World Cup record which was just set last week in Tokyo. Rapsys ranked fourth in the same event at the World Championships. China's Ji Xinjie came second in 3:49.87 while Aussie swimmer Thomas Fraser-Holmes was third in 3:54.20.

"I thought this guy (Ji Xinjie) is going to be more faster," Rapsys said.

The men's 200m back was a battle of three swimmers. At last Australia's Mitchell Larkin won this time in 1:56.39, while his teammate Tristan Jason Hollard trailed in 1:57.94. China's Xu Jiayu, who led the first split, fell behind and settled for the third place in 1:59.59.

"I am not worrying too much about the time," Larkin said. "But I am very happy to win. I enjoyed the competition very much."

Xu, winner of the event at the World Championships, said: "I felt very tired and I am not in my best form now. Recently I took much time in my study."

The women's 200m fly was a close race between Hungary's Olympic champion Katinka Hosszu and her teammate Zsuzsanna Jakabos, but Hosszu ended up winning in 2:07.26. China's Zhang Yufei came third.

"After the World Championships we don't have time to make adjustment, so I just carried through. The World Cup is more relaxed than the World Championships. I think it is a fun way to just enjoy swimming for what it is and not what you have to do. You choose your events and see what you can do," the Hungarian "Iron Lady" said.

The men's 100m butterfly title also went to Hungary as Szebasztian Szabo dominated the race in 51.45.

Vitalina Simonova of Russia won the women's 200m breast, while China's Yu Jingyao ranked second.

Australia's Cate Campbell grabbed the women's 50m free title, while the men's 50m free gold went to Russia's Vladimir Morozov.

Jinan is the second leg of 2019 FINA Swimming World Cup and runs from August 8 to 10.
