Kazakhstan's teenage prodigy Zulfiya Chinshanlo powered her way to weightlifting gold in the 53kg category on Sunday, breaking her own world record in the clean and jerk.

The 19-year-old posted a snatch of 95kg before making history with 131kg in the clean and jerk, one kilogram more than her effort at last year's world championships.

The total of 226kg gave a six kilo winning margin ahead of Hsu Shu-Ching of Chinese Taipei, who took the silver, and Moldova's Cristina Iovu.

Hsu was awarded the silver over Iovu due to a lesser bodyweight.

China's 17-year-old prodigy Zhou Jun, one of the favorites for gold, was a surprise early casualty, failing to snatch 95kg after being entered by Chinese officials in the weaker "b" group.

Another contender, Yuderqui Contreras of the Dominican Republic, also crashed out in the snatch after dropping all three attempts at 94kg.
