Australia’s Zac Stubblety-Cook set an Olympic record in the 200-meter breaststroke, capturing the gold medal in 2:06.38.
Arno Kamminga of the Netherlands earned the silver medal, in 2:07.01, followed by Matti Mattsson of Finland with the bronze.
The men’s 200-meter breaststroke, a do-not-miss for fans who do like lots of splashing, was thought to be an open race, maybe a chance for Anton Chupkov of the Russian Olympic Committee to flirt with the world record he already holds.
Chupkov won the bronze medal in Rio at 19-years-old, and came to Tokyo five years later with a new set major titles under his belt.
