Australians Taliqua Clancy and Mariafe Artacho del Solar have added another gold medal to their growing collection after victory at the World Tour of beach volleyball event in Portugal.
The fifth-seeded Clancy and Artacho del Solar overcame the United States team of Sara Hughes and Summer Ross 15-21 21-15 15-8 in the semi-finals before they eased past Brazil's Maria Antonelli and Carol 23-21 21-17 in the decider.

The Espinho Open title is their biggest win since combining less than a year ago.
