David Roberts added to Wales' medal haul in Melbourne with bronze in the 100m EAD freestyle.
Roberts says the performance was for his family
He was beaten by Australia's Matthew Cowdrey and Canada's Benoit Huot.
"It's a long way from home, my parents and girlfriend are watching on the television so that performance was for them," said Roberts.
Wales' hopes of a pool gold were lifted when David Davies was the fastest qualifier by a full 13 seconds in the heats for the men's 1500m freestyle.
The City of Cardiff swimmer is a strong favourite for Tuesday's final.
