Zou Shiming won a bronze medal in the 2004 Olympic Games and gold medals in the 2008 and 2012 Games. But when the flyweight from China did not stop any of his first three opponents inside the distance, he had some wondering if that amateur success was going to translate to the professional level.

Shiming on Saturday finally came through with his first knockout as a prize-fighter, stopping Yokthong Kotietgym of Thailand at 2:09 of the seventh round in Macau, China. Their bout was slated for eight rounds.

Shiming, 32, is now 4-0 with 1 knockout. Kotietgym, just 19, is 15-4.

Their bout was televised on HBO2.
