Liz Cambage scored 17 points and grabbed 10 rebounds, leading Australia to a 70-66 victory over Russia in women's basketball.
Cambage dunked in the third quarter and, more importantly, hit a pair of free throws in the final minute to seal Australia's second straight win and hand Russia its first loss of the tournament.
Suzy Batkovic added 15 points and Jenna O'Hea finished with 10 for the Aussies, who improved to 3-1 and moved into a tie with Russia for second place in Group B. Australia will complete round-robin play on Sunday against Canada.
The Russians had won each of their first three games, none by more than 10 points, and will take on unbeaten France in its Group B finale on Sunday.
Irina Osipova led Russia with 15 points and nine rebounds, while Alena Danilochkina chipped in 13 points in defeat. Becky Hammon scored 12 for Russia, which never led after the first quarter.
The Aussies opened an 11-point lead midway through the third when Cambage's bucket made it 44-33, but Russia quickly trimmed its deficit to three and went into the fourth down 54-48.
Australia pushed its lead to as many as eight in the final period, but Russia managed to keep it close and Hammon's basket with 50 seconds remaining made it a 68-66 game. Cambage followed with a pair from the stripe and Russia, despite four offensive rebounds in the final 30 seconds, could not answer.
