Canadian 15-year-old Summer McIntosh has won another gold medal and Italy pipped the United States to the men’s 4x100 medley relay title on the last night of racing at the world swimming championships in Budapest.

Kristof Milak is the dominant force in swimming's butterfly event and the man who broke Michael Phelps' 10-year-old world record in the 200-meter fly at the world championships in 2019.

Finally, a gold medal in Tokyo for Katie Ledecky.

Hungary's Kristof Milak grabbed gold in the men's 200m butterfly -- in an Olympic record-worthy 1:51:25.
