Hungary’s Katinka Hosszú claimed a hat-trick of gold medals on the second day of the International Swimming Federation (FINA) Swimming World Cup in Berlin.

Hosszú, the reigning World Cup champion, won the women’s 400 metres individual medley yesterday and added further gold 24 hours later.

She set a world record of 56.51sec in the 100m individual medley final to win the first race of the day at the Europa Sportpark.

Sweden's Sarah Sjostrom followed her onto the podium in 57.30, while Alia Atkinson of Jamaica completed the top three in 58.12.

Hosszú's dominance extended to the women's 200m backstroke where she touched the wall in 2min 00.37sec to record her third gold medal in the German capital.

Australia's Emily Seebohm finished narrowly behind in second in 2:00.65.

Home favourite Nadine Laemmler of Germany won the bronze medal in 2:05.41.

Hosszú sealed a fourth and final title for the meet in the women's 100m butterfly.

She finished over half a second quicker than her nearest rival in 55.86 with Italy's Ilaria Bianchi having to settle for silver in 56.42.

Belgium's Kimberly Buys rounded out the top three with her time of 56.44.

New rules for this World Cup season only permit swimmers to enter four individual events per meet, meaning Hosszú's work was done.

Records continued to tumble, though, as The Netherlands' Ranomi Kromowidjojo set a world best in the women's 50m freestyle final.

The three-time Olympic champion touched the wall in 22.93 with Sjostrom claiming her second silver of the day in 23.00.

Cate Campbell of Australia finished third in 23.62.

Atkinson managed to take one gold medal this evening as her time of 1:03.16 saw her win gold in the women's 100m breaststroke.

Finland's Jenna Laukkanen took the silver medal in 1:04.56 and Belgium's Fanny Lecluyse the bronze in 1:05.81.

Tom Shields of the United States finished in second in 1:49.26, just in front of Japan's Masayuki Umemoto, who swam 1:52.80 for third.

Le Clos had to settle for bronze in the men's 200m freestyle as Hungary's Dominik Kozma took the gold medal in 1:41.03.

Poland's Kacper Majchrzak finished in second place in 1:41.62 as Le Clos touched the wall third in 1:41.67.

There was further success for South Africa in the men's 50m breaststroke, however, as Cameron Van Der Burgh took the gold medal in 25.49.

Italian Fabio Scozzoli finished second in 25.77 and Russia's Kirill Prigoda third in 25.86. 

Poland's Radoslaw Kawecki took gold in the men's 100m backstroke in 49.97.
