Having dominated the first five legs of the series in Paris-Chartres, Berlin, Moscow, Beijing and Dubai, Hosszú showed no signs of letting up at the Hamad Aquatic Centre in Qatar’s capital.

The 27-year-old’s first victory of the day came in the women’s 200 metres freestyle, clocking a time of 1 min 53.29sec to beat nearest challenger Madeline Groves of Australia by 1.17 seconds and fellow Hungarian Zsuzsanna Jakabos by a further 0.21 seconds.

A time of 26.38 in the women’s 50m backstroke proved enough to secure Hosszú’s second win as Ukraine’s Daryna Zevina finished runner-up in 26.53 and China’s Cheng Haihua took third spot in 27.01.

There were also victories for the Iron Lady in the women’s 200m individual medley and the women’s 800m freestyle with times of 2:05.77 and 8:27.58 respectively.

China’s Fang Yi was the biggest threat to Hosszú in the 800m freestyle, touching home in 8:30.29 to finish second ahead of Jakabos in 8:31.27.

A time of 45.77 saw him win the men’s 100m freestyle with South Africa’s Chad le Clos second in 46.00 and Japan’s Katsumi Nakamura third in 46.83.

Morozov followed this up with victory in the men’s 100m individual medley, posting a time of 51.75 to better runner-up Philip Heintz of Germany by 0.52 seconds and third-placed Pavel Sankovich of Belarus by 0.93 seconds.

Another double gold medallist in men’s competition was Japan’s Daiya Seto, who topped the podiums in the 200m butterfly and 400m individual medley.
