For Oishi the bout will be his first defense of the title, a title that he won last year when he upset Takayuki Hosokawa. The win was a huge one for Oishi, but seemed to be just as much about Hosokawa being a spent force as Oishi being something special. The win saw Oishi work hard, and earn the victory, but really not look like a great fighter coming of age.
At 32 years old Oishi is a veteran, and one whom debuted back in 2008. He suffered a number of early career set backs and had a 7-3 (4) record after 10 fights, with a notable loss in the 2011 All Japan Rookie of the Year final. Since then he has gone 7-2 (3) suffering a notable loss to Zac Dunn and scoring his career defining win over Hosokawa. That win over Hosokawa was Oishi's third straight win and interestingly it was the 7th straight win whilst actually fighting at Light Middleweight for Oishi, who is 7-1 at the weight!
Thai challenger Ratchasi, also known as Niwat Kongkan, is a 31 year old who debuted back in 2011 and has had miced success, losing by stoppage to Hikaru Nishida and Cobra Suwa, before defeating Suwa in a rematch last year. The win over Suwa is the most notable win on his record, but with two stoppages on his record, and a 0-1 record outside of Thailand, it's unclear what he really has to offer.
Footage of the Thai is scarce though from what we under-stand he was a hard working but limited fighter who is unlikely to score a stoppage at this level but could make for a good fun bout with a limited foe, such as Oishi. The styles should gel well, but it's hard to see the bout being fun, or exciting, with the Thai unlikely to over-come the Japanese local.
Although we struggle to defend this bout an as OPBF title fight, it should be a fun fight all the same, pitching two limited and beatable fighters against each other,
