Summer McIntosh equals Phelps feat with her fourth gold at World Aquatics Championships, US break world record in women’s 4x100m medley

China’s 12-year-old sensation Yu Zidi had to settle for fourth on the final night of the World Aquatics Championships on Sunday as Summer McIntosh capped a brilliant few days to win the women’s 400 metres individual medley.

McIntosh’s fourth gold in Singapore made the 18-year-old Canadian only the third swimmer to win five individual medals at one edition, emulating Michael Phelps and Sarah Sjostrom.

It came on a day when Pan Zhanle suffered further disappointment, as China failed to reach the men’s 4x100m medley relay final – the event in which he shocked the world at the Olympics.

Later, the United States set a world record in the women’s 4x100m medley relay to ensure they topped the medals table with nine golds, one ahead of Australia.
