Ottawa: American swimming star Michael Phelps posted his second victory in two days, capturing the men's 100 metre butterfly at the Canada Cup swimming competition.
The 14-time Olympic gold medalist Phelps clocked 51.32 seconds to beat his American compatriot Chris Brady by more than a second.
On Saturday, Phelps cruised to victory in the 200 metre freestyle in the event which serves as a tune up for the World Championships in two weeks in Shanghai, China.
Phelps won a record eight gold medals at the 2008 Beijing Olympics and set seven world records, becoming the most decorated Olympic athlete in history.
In 2009, a British tabloid published a photo of Phelps using a marijuana pipe, resulting in a three-month suspension by USA Swimming.
Other winners in men's competition Sunday included Brett Hayden of Canada in the 50 metre freestyle and Scott Dickens of Canada in the 200 metre breastroke.
On the women's side, Canada's Katerine Savard won the 100 metre butterfly in 58.68 seconds to beat out Phelps for the meet's top performer award.
