The Thai, a former WBA Interim champion, is currently riding a 6 fight stoppage run, with 3 fights already this year. Although not one of the divisions's biggest names the Thai warrior is one of the more exciting men in the division and has been involved in thrilling bouts with the likes of Koki Eto, Takuya Kogawa and Juan Carlos Reveco.
From what we understand he is chasing a late 2016 or a 2017 bout with Casimero.
As for Casimero, who has previously held titles at 108lbs, the bout could be his first defense following his recent stoppage upset win against Amnat Ruenroeng in China. Casimero twice dropped Ruenroeng en route to claiming toe IBF title, and avenging his 2015 loss to the tricky Thai. It would seem likely that he could lured into Thailand to take on Yodmongkol, though he would likely be paid well for travelling.
