Australia’s Cameron McEvoy has won a bronze medal in the men’s 50-metre butterfly at the world championships in Doha.

McEvoy (23.08 seconds) finished behind Portuguese teenager Diogo Ribeiro, the surprise winner in 22.97, and Michael Andrew of the United States.

The bronze medal is McEvoy’s first global medal in butterfly, although the 50m butterfly is not an Olympic event.

The 29-year-old became the oldest Australian to win a swimming world championship in the 50m freestyle last year in Japan. He will aim to defend that title later in the week.

McEvoy’s 20-year-old teammate, Isaac Cooper, put in a storming swim but finished just outside the medals in 23.12, edged out after being unable to sustain a bright start.

Like Cooper, fellow Australians Sam Williamson and Brianna Throssell were also forced to settle for fourth place in their respective events.

Williamson was fourth in the 100m breaststroke, behind gold medallist Nic Fink, of the United States, who led from start to finish.

Fink beat Italy’s Nicolo Martinenghi into second, with three-time Olympic champion Adam Peaty third. Peaty, who has won the event on three occasions, had missed the last two editions.

“It’s definitely crazy getting the first worlds gold in the 100 at the age of 30,” Fink said.
