England's Adam Peaty swam well within his capabilities to clinch the men's 100m breaststroke at the Gold Coast Commonwealth Games on Saturday.
The 23-year-old Peaty, who has labelled his ambitions to crack 57 seconds for the race as Project 56, clocked 58.84 seconds to beat fast-finishing compatriot James Wilby to defend the Commonwealth Games title he won in Glasgow four years ago.
Wilby clocked 59.43 seconds with South Africa's Cameron van der Burgh taking bronze 0.01 seconds behind the Englishman.
Peaty had swum a Commonwealth Games record 58.59 on Friday but appeared to be content to just win the race rather than challenge his own world record of 57.13 that he set at the Rio Olympics in 2016.
Australia's Cate Campbell claims 50m freestyle gold
Australia's Cate Campbell claimed her second gold medal of the Gold Coast Commonwealth Games when she won the women's 50 metres freestyle title on Saturday.
The 25-year-old clocked 23.78 seconds, just outside the world record of 23.67 set by Sweden's Sarah Sjostrom at last year's world championships in Budapest.
Campbell also anchored the host nation's 4x100m freestyle relay team to a world record on the opening day of competition on Thursday.
Her younger sister Bronte and Canada's 200m freestyle champion Taylor Ruck dead-heated for second in 24.26.
