World Boxing Council minimumweight champion Wanheng Menayothin defeated Pedro Taduran by decision in Nakhon Sawan, Thailand, to retain his belt for the tenth time and break Floyd Mayweather’s 50-0 career record. Menayothin started slowly in the first two rounds, but little by little he started to dominate the fight. At end of the fourth round, WBC’s open scoring was revealed, and the champion was ahead by 40-36, 40-36 and 39-37.

The referee deducted a point from Taduran during the eighth round. He had previously been warned to keep his punches up but it represented a serious setback for a fighter who already knew he was appreciably behind on the scorecards. At the end of the eighth round, the open scoring had the fight in Wanheng’s favor 78-74 twice and 79-74. It meant Taduran would need to win all four of the remaining rounds just to secure a draw, but the experience of the seasoned champion made a significant difference.

The final tallies were 115-111, 118-108 and 117-110, all in favor of Menayothin.
