Later, the United States won the women's 4x100m Medley Relay as the quartet of Regan Smith, Lilly King, Torri Huske and Claire Curzan proved too strong for silver medallists Australia and third-placed Canada.

This was USA's 45th medal of the week as they finished .47 seconds ahead of Australia and 1.23 ahead of Canada.

"We take a lot of pride in that relay and really wanted to put in a good time and get that gold back from last summer (Olympic Games). We came out and did that, and it was a great race," said Curzan, who anchored the U.S. home.

“Yeah, I’m pretty tired,” Huske said after her sixth medal in a busy week.

Canadian swimmers finished with 11 medals for their most successful worlds.
