Beijing:Roberto Cammarelle of Italy has won the super heavyweight boxing gold medal in the final Olympic bout, stopping China's Zhang Zhilei in the final round for his second Olympic medal.
Cammarelle is the defending world champion and a bronze winner in Athens. He picked apart the larger Zhang with combinations and sharp hooks Sunday before staggering him to the canvas early in the fourth round.
The referee stopped the bout 19 seconds into the round because of the serious head blow.
Cammarelle emphatically prevented China from winning its third boxing gold of the day. China and Russia paced the overall Beijing tournament with two gold medals apiece, while Cuba led with eight total medals but no golds.
