Swimmer Bobby Finke has won the men's 1500 meter freestyle, his second gold medal of the Tokyo Games after earlier winning the men's 800 meter freestyle.
Finke's victory means the Americans have taken home the top prize in all four distance swims in Tokyo. Team USA's Katie Ledecky won both the women's 800 meter and 1500 meter freestyle races.
Finke's race was a nail-biter, with the American, Ukraine's Mykhailo Romanchuk and Germany's Florian Wellbrock separating themselves from the rest of the pack. Romanchuk finished with silver and Wellbrock with bronze.
World record-holder Sun Yang of China was banned from competing in this year's Games due to a doping violation.
