Wanheng Menayothin retained his WBC minimumweight title on Saturday night with a unanimous decision victory over Omari Kimweri in Rayong, Thailand.
The undefeated 31-year-old Thai, making the seventh defence of his green belt, also moved one step closer to matching the records of boxing legends Floyd Mayweather and Rocky Marciano with his 47th win.
Menayothin received a cut on his left eyelid following a clash of heads just two minutes in but still managed to overcome his Australia-based Tanzanian challenger on points.
Kimweri, 34, was deducted a point for the accidental clash but faced an uphill battle as the more skillful champion remained in control throughout.

Menayothin eventually took the victory, winning on the cards of all three judges, 117-110, 118-109, 118-109.
Menayothin now stands at 47-0, leaving him just two wins from equalling the records of Mayweather and Marciano (49-0).
