Katinka Hosszu and Zsuzsanna Jakabos continued their rhapsody of Hungarian 1-2 finishes as the Moscow round of the World Cup drew to a close, Hosszu taking three more victories to take her growing cash pile beyond $40,000 so far on this tour.
In the 400m medley, Hosszu clocked 4:30.14, Jakabos on 4:30.80, American 15-year-old Becca Mann on 4:35.87 and a clear threat to the future of those she is slated to race against again in senior waters in the years ahead.
The same trio were back on the podium in no time at all: in the 200m butterfly, it was Hosszu again, a 2:05.77 pipping Jakabos by 0.29sec, Mann on 2:11.35.
Hosszu then cruised into 8th place in 4:15.41 over 400m freestyle as she took a breather, the race won by Elenea Sokolova (RUS) in a battle with Leah Smith - another US junior gaining experience with every stroke - that ended 4:04.83 to 4:05.04, Melissa Ingram (NZL) third in 4:06.20.
Having taken a rest, Hosszu was back in to take the 100m medley in 59.69, Theresa Michalak (GER) and Sophie Allen (GBR) threatening with a joint 59.98 for shared silver, Jakabos locked out in 1:00.31.
Hosszu has now won 25 finals on tour, converting, with her other placings, to $41,000 in earnings, courtesy of sponsor Arena.
Elsewhere, Fabio Scozzoli (ITA) clocked 58.32 to hold off China's Gu Biaorong, on 58.72. Gu, 23, sat out the long-course season in 2011. His long-course best in 2009 was 1:02.43 and in 2011 1:02.63, while he arrived on world cup tour this year with a lifetime short-course best of 1:00.37 from a year ago. In Moscow today, Sergei Geibel (RUS) locked Sean Mahoney (USA) out 58.89 to 59.44 for third.
Britta Steffen (GER), 2008 double Olympic champion, cracked 53sec once more with a 52.92 win in the 100m freestyle, Jessica Hardy (USA) the only other inside 54sec, on 53.74.
Daiya Seto (JPN) started the session with a 15:03.02 win in the 1500m freestyle and then took down Lazslo Cseh in the 200m medley, 1:53.93 to 1:54.31, Darian Townsend (RSA) and Kenneth To (AUS) joint third in 1:54.63 each.
Townsend had earlier kept fast-finishing Paul Biedermann (GER) and Australian Tommasso D'Orsogna at bay 1:44.26 to a shared 1:44.49 second place in the 200m freestyle.
Olympic silver medallist for Russia, Evgeny Korotyshkin, coached by Andrea Di Nino in Italy, pipped his teammate Nikolay Skvortsov 50.56 to 50.82 in the 100m butterfly, American Thomas Shields on 50.89 to lock out the winner's training partner Jason Dunford (KEN), on 51.67.
Rachel Goh (AUS) clocked 57.80 in the 100m backstroke for victory ahead of two Brazilians who switched places in terms of where they have traditionally finished in relation to each other. Etiene Madeiros, 21, arrived on world cup tour sporting a lifetime best of 1:00.18 short-course, from 2010. Today she took second in 58.93. Fabiola Molina took third in 59.25. In May, 2011, she set what remains her best long-course time - 1:02.29.
George Bovell (TRI) got the better of Anthony Ervin (USA) and Evgeny Lagunov (RUS) in the freestyle dash, 20.90 to 21.11 and 21.80, while Rie Kaneto (JPN) was victorious over 200m breaststroke once more, her 2:20.08 dominating, Maria Temnikova (RUS) and Mio Motegi (JPN) on 2:22.94 and 2:23.02 respectively.
Japan had more success when Yuki Shirai and Hayate Matsubara finished 1-2 in the 200m backstroke, on 1:50.80 and 1:51.96, Matsubara overhauling Ashley Delaney in the second half of the final, the Australian taking third in 1:53.36.
