Benjamin Karl of Austria and Hilde-Katrine Engeli of Norway won gold medals in the parallel slalom events Saturday at the snowboard world championships in La Molina, Spain.
Karl won his second title of the championships after overtaking Switzerland's Simon Schoch in the second run.
Karl also won the parallel giant slalom on Wednesday, and was the defending champion in Saturday's event.
Rok Marguc of Slovenia beat Austrian rider Andreas Prommegger for the bronze medal.
Matthew Morison of Burketon, Ont., was seventh.
"I raced strong today, but unfortunately couldn't find the speed to beat Schoch," said Morison. "My riding and racing is very close to getting back on the podium, I just need to make a few very small changes, both technically and mentally, going into race day."
In the women's race, the 22-year-old Engeli beat Olympic champion Nicolien Sauerbrelj to win the final by 0.92 seconds.
Claudia Riegler raced past Heidi Neururer for the women's bronze after capitalizing on her fellow Austrian's fall in the first run.
