I'm in China right now, unable to access Youtube, so I'm going all the way back to December 2010 for this bout, the final of the inaugural Thai Fight Tournament.
The winner got a heap of prizes including an Isuzu (yes, this tournament is also funded by Isuzu Motors), a million baht (approx. 33k USD), sponsors, and a lot exposure.
Pinca fought his way through Sharos Huyer and Rafi Zouheir, and Petmankong went through Zhou Hong Zhang and Vitaly Gurkov to meet in the semi-finals. There were questions about whether Petmankong, previously a 126 lb and 135 lb fighter, could be successful in the 147 lb tournament, but he'd proved more than skillful enough to handle his first two opponents. Pinca had been making a name for himself facing high quality Thai opponents, but had come up short against elite fighters like Kem Sitsongpeenong, Saenchai Sor Kingstar, and Attachai Fairtex. He himself was not a a large fighter for 67 kg, having fought at 140 lb a number of times.
Pinca wears the blue in this bout, Petmankong the red.
(As I said, Youtube is blocked in China, so I'm actually viewing the bout here: http://v.youku.com/v_show/id_XMjI5NjM5NTc2.html)
