By Steve Keating RIO DE JANEIRO (Reuters) - The United States women's basketball team will be out to prove their credentials as one of the Olympics' great sporting dynasties on Saturday when they take on Spain in the gold-medal final. A victory over Spain, who have never won a medal in women's basketball, would mark a sixth straight trip to the top of the Games podium for the all-conquering Americans, making them one of the greatest teams to ever grace the Olympic stage. Only the U.S. men and India's male hockey players can claim such a run of domination in an Olympic team sport.
