Japanese boxer Naoya Inoue knocked out Filipino opponent Marlon Tapales in the 10th round Tuesday to become the undisputed super bantamweight champion of the world, the second man to unify all four major belts in two different weight classes.
The fighter nicknamed "Monster" put on another dominant performance at Tokyo's Ariake Arena as he added Tapales' World Boxing Association and International Boxing Federation crowns to the World Boxing Council and World Boxing Organization titles he already held.
Inoue fought on the front foot from the bout's outset and scored the first knockdown late in the fourth round, getting Tapales on the ropes before he was saved by the bell.
