Mayweather dominated Nasukawa, scoring three total knockdowns in the first round before the fight was stopped.
Cries immediately went out of Mayweather performing another money grab and it certainly appeared to play out that way, as the fight happened on New Year's Eve in Japan. 50-0 Mayweather does not get to add another digit to his record given the status of this match-up but he does get to add $9 million to his bank account, not bad for 139 seconds work. "It was about entertainment and we had fun", Mayweather said, with Nasukawa in tears after the fight.
Mayweather, 41, a former five-weight world champion who retired from boxing with a flawless professional record of 50-0 last year, saw off an opponent 21 years his junior on Monday night.
Mayweather said he had been "blindsided" into the contest by the organisers. Although the result was getting knocked down I do not regret (taking the fight). "Tenshin, hold your head up high, I want fans around the world to support Tenshin, he's a great guy and a great champion".
