Germany's Hase and Volodin tango to Olympic pairs figure skating lead
The German duo scored a personal-best 80.01 points for their high-flying routine while favourites Riku Miura and Ryuichi Kihara of Japan were down in fifth place with 73.11.
Georgia's Anastasiia Metelkina and Luka Berulava (75.46) were second, narrowly ahead of Canada's Lia Pereira and Trennt Michaud (74.60) going into Monday's free skate.
The Germans hit all the right notes after a slight wobble at the start of a powerful and fast-moving tango that wowed the judges.
"I thought to myself, don't make another mistake now," said Hase.
