Australia broke its own world record in the women's 4x100-meter freestyle relay to capture the country's first gold in swimming at the Tokyo Olympics.
The quartet of Bronte Campbell, Meg Harris, Emma McKeon and Cate Campbell finished in a time of 3:29.69, which was close to four-hundredths of a second better than Australia's previous world record of 3:30.05.
The United States benefited from a strong third leg out of Natalie Hinds to set anchor Simone Manuel up for a medal-clinching lap.
Manuel finished third right behind Canada's Penny Oleksiak to earn the Americans' sixth medal in the pool on Saturday night.
