Natalia Ishchenko and Svetlana Romashina extended Russia's domination of synchronised swimming with an Olympic gold medal in duet on Tuesday.
The Russians improved on their free score from the preliminaries, finishing with a total of 197.100 points. They haven't lost an Olympic synchro event since the 1996 Atlanta Games.
The only real drama was for silver, which went to Spain's Ona Carbonell and Andrea Fuentes with 192.900 after a lively, Tango-themed routine that had the crowd at the Aquatics Centre clapping along nearly the whole way.
China's Huang Xuechen and Liu Ou improved on their score from the prelims with an impressive display of legwork, but the duo's athleticism wasn't enough to hold off Spain. They finished with 192.870.
