United States' Tom Shields upset South African world champion Chad le Clos in the men’s 100 metres butterfly to top the bill on the second day of the International Swimming Federation (FINA) World Cup in Moscow.

Shields, who also overcame Le Clos in the semi-finals of last week's World Championships in Kazan before placing only fourth in the final, won in a time 51.36, with the South African second and another American third in the form of Tim Phillips.

It was a case of after the Lord Mayor's show for Le Clos, whose time of 51.45 was almost a second-down on his 50.56 last week, the second fastest time in the world this year behind Shields and Phillips' compatriot Michael Phelps.

Hungarian star Katinka Hosszu added two more victories today to add to the two she garnered last night, showing her speed over the shorter distance to win the 100m frestyle in 54.10 before overcoming a depleted field of just five swimmers to take 400m indivdual medley spoils, almost six seconds slower than her time in Kazan.

The 26-year-old also claimed 100m backstroke silver behind Australia's Emily Seebohm, who won in 58.88, as well as 400m freestyle bronze.

Shao Yiwen of China won the latter event in 4:07.30.

There was South African success elsewhere as, in the absence of British world champion Adam Peaty, Cameron van der Burgh cruised his way to 100m breaststroke victory in 59.27 to add to his 50m triumph yesterday.

Russia also enjoyed a home win courtesy of Danila Izotov, who touched in 1:46.93 to win the 200m freeestyle ahead of South Africa's Myles Brown and team mate Nikita Lobintsev, while Vitalina Simonova won the 200m breaststoke in 2:22.94.

But it was the US who enjoyed the best of the night, with Katie Meili enjoying a second victory of the meeting in the 50m breaststoke, winnng in 30.76 ahead of compatriots Breeka Larson and Lilly King in an American clean sweep.

Cammile Adams won the 200m butterfly in 2:06.33 while Josh Schneider took 50m freestyle honours in 21.80.

Other winners included France's Camille Lacourt in the 50m backstroke, Germany's Philip Heintz in the 200m individual medley and Australia's Ashley Delaney in the 200m backstroke.

The World Cup series is now due to move to France for the brand new leg in Chartres-Paris on Saturday and Sunday (August 15 and 16).

It comes at the start of a revamped eight-leg Series taking place in a 50m pool, with overall prize money having been boosted to $2 million (£1.3 million/€1.7 million) and the added incentive of Olympic qualifying places having been introduced.
