Onaga, ranked #13 by the IBF at Super Flyweight, had been inactive since October 2013 though made a triumphant return to action as he made light work of Thai journeyman Samransak Singmanasak (35-24-1, 27).
Singmanasak was returning to Japan for his second fight of the year following a 4th round loss in April to Tetsuma Hayashi. Unfortunately for the Thai this loss to Onaga was his 4th successive stoppage loss following not just the defeat to Hayashi but also back-to-back defeats to Randy Petalcorin. This also leaves the Thai with a 1-6 record in Japan.
For Onaga, a former 2-time Japanese title challenger, this win could kick start his hopes of finally winning a professional title. To do that however he will likely need to defeat Sho Ishida, the current Japanese champion.
