Reigan Eersel defended his lightweight Muay Thai title in the main event of ONE Fight Night 9.

In the main event, reigning two-sport champion Eersel dropped challenger Sinsamut Klinmee with a crushing body shot in the fourth round of their highly anticipated rematch to retain his title.

Sinsamut was strong and powerful, pushing the pace early with thudding combinations in the first two rounds against the defending champion. Meanwhile, Eersel picked his spots, opting to dissect his Thai counterpart with clean striking.

In the co-main event, Thai superstar Muangthai PK Saenchai took care of business against countryman Kulabdam Sor Jor Piek Uthai to win by knockout in the third stanza.
