Naoya Inoue scored his 17th professional victory and 15th via knockout in the very first round as he defended his World Boxing Association (WBA) World Bantamweight Title for the first time.
The fight took place at the Arena in Yokohama, Japan, and was the first round in the World Boxing Super Series (WBSS) for bantamweights with Inoue coming in as the second seed in the tournament.
The fight only lasted 70 seconds, with Inoue landing the first right hand he threw a minute into the round that cracked the chin of Payano and put him down for the ten count.
Inoue continues to impress all boxing fans, as he came into the fight with a similar destruction of longtime reigning WBA champion Jamie McDonnell in May.
Inoue now looks to face the winner of the highly anticipated upcoming bout between Jason Moloney and Emmanuel Rodriguez in Orlando, Florida.
