Fuelled by the loss of the 200m title to Léon Marchand, Kristof Milak added the 100m butterfly title to his pantheon in 49.90sec ahead of a Canadian grab of the silver and bronze.

Milak is the first Hungarian to claim the title since 1968, when the 100 joined the 200 in the Olympic program. In victory he moved up a place from his silver in Tokyo three years ago.

There was nom defence of the crown today: Caeleb Dressel, of the USA, finished 13th in 51.57 in semis yesterday.

Milak turned fourth in 23.40, 0.17sec behind Dutch challenger Nyls Korstanje with Canadian Josh Liendo second through in 23.24 and his teammate Ilya Kharun on 23.73 in seventh.

The 2021 Olympic 200m champion and World record holder, Milak produced the best return, of 26.50, for gold in 49.90, just 0.09sec ahead of Liendo, whose 49.99 wrote several lines in history:

• the first black Canadian to make the Olympic podium
• the fifth man ever to race inside 50
• inside the 50.06 at which he'd held the Commonwealth record for the past year

Canadians celebrated not only one bite of the cherry but two: Khan powered his way through the field to rise from seventh to level fourth with Tokyo bronze medallist Noe Ponti, of Switzerland.

The lunge for the wall favoured Kharun: bronze was his in 50.54, 0.01sec ahead of Ponti. Canada had waited 52 years for a medallist - and then two came two.

The last Canadian to make the medals was Bruce Robertson, who took silver behind the fourth of seven golds won by record-breaking American Mark Spitz.
