The U.S. used three of its four swimmers from the 2012 Olympic final — Ryan Lochte, Ricky Berens and Conor Dwyer. Charlie Houchin, who swam in the prelims in London, replaced Michael Phelps.The Americans were a solid but not overwhelming favorite.
Russia (Danila Izotov) led France (Yannick Agnel) by three tenths and the U.S. (Dwyer) by six tenths after the first leg, each nation using its medalist from the individual 200 free on leadoff. Lochte propelled the U.S. into the lead on his last turn of the second leg. Houchin and Berens extended the edge over Russia to a full body length to win easily.
China‘s Sun Yang swam the second fastest relay split in history (1:43.16) to steal the bronze from the French.
The U.S. won its fifth straight world title in the event. Lochte finished a perfect night, two golds and qualifying first in the 100 butterfly. He now has three golds, one silver and a fourth with two finals left.
