Naoya Inoue raises his record in widely recognized world title fights to 19-0 (17 KO) and becomes the first fighter from the Pacific Rim to become an undisputed champion in the four-belt era by scoring a 10-count KO in round 11 over Paul Butler thanks to a powerful combination along the ropes.

"The Monster" stalked the mobile, defensive-minded Englishman from start to finish, and in the middle rounds he tried to induce exchanges by dropping his hands, flashing an "Ali Shuffle," employing the Roy Jones "chicken pose" and crossing his arms behind his back while sticking out his chin. After Butler refused to take the bait, Inoue returned to Monster mode and finished the job with typical power and efficiency.

The final numbers further illustrated Inoue's physical and psychological dominance: He was much more active (64.1 punches per round to Butler's 29), jabbed better (37.8 attempts/5.2 connects per round to Butler's 18.1/0.96), slammed the body (he led 59-22 in connects), prevailed 151-38 overall, 54-10 jabs and 97-28 power, was more accurate in all phases (23%-13% overall, 14%-5% jabs, 36%-25% power) and out-landed Butler in every round in terms of total punches. Scoring: 100-90 (3x).
