Vladimir Morozov and Katinka Hosszú each grabbed two gold medals on the second day of the International Swimming Federation Swimming World Cup in Jinan in China.

Both swimmers led the World Cup rankings at the end of the first leg of the series in Tokyo and continued to impress at the Natatorium of the Jinan Olympic Sport Centre.

Morozov followed up yesterday's 50 metres freestyle gold by setting a World Cup record to win the 100m freestyle final before claiming the 50m backstroke  gold with a World Cup record-equalling 24.42sec.

The Russian clocked 47.99 to top the men's 100m freestyle podium, with American Blake Pieroni second in 48.15.

Szebasztián Szabó of Hungary claimed bronze in 48.63.

Morozov equalled the 50m backstroke record for a third gold medal in two days as he pushed Michael Price of the United States into second.

Price touched the wall in 24.85 for second place as Chinese Jiayu Xu took bronze in 25.25.

Three-time Olympic champion Hosszú secured double gold by winning the women's 100m backstroke and 400m medley races.

In the 100m backstroke, the Hungarian edged out Australian Emily Seebohm by just 0.11 to clinch gold in 59.65.

Jakabos clocked 4:45.28 for silver, while Xin Liu of China rounded out the top three in 4:49.72.

Australian Cate Campbell won the 50m butterfly in 25.63 as compatriot Mitch Larkin claimed gold in the men's 200m medley.
