Boyanka Kostova of Azerbaijan set two new world records on her way to victory in the 58kg category at the World Weightlifting Championships in Houston. The Bulgaria-born powerhouse, who switched allegiances to Azerbaijan in 2010, set new records for the snatch (112 kg) before adding a new overall total record (252kg) with her final lift. She failed to add a third record in the clean and jerk, settling for 140kg, but said she is confident of threatening the record at next year's Olympics. In the men's 69kg Shi Zhiyong won gold for China.
