Christopher Zeller scored in the 45th minute for the Germans, who came away with a 2-1 victory in the Group B match. They topped Spain four years ago in Beijing for the gold medal.
Australia, which won bronze in Beijing, cruised to a 6-0 win against South Africa in a Group A contest. The Australians have the longest-running medal streak in the competition, having won medals in the previous five Olympic games.
