Guillermo Rigondeaux (15-0, 10 KOs) put one of his most exciting performances Wednesday -- it just took traveling halfway around the world to do it.

The two-time Olympic gold medalist engaged in a war with Hisashi Amagasa, rising off the canvas twice to stop him in Round 11.

Amagasa (28-5-2, 19 KOs) was dropped twice in Round 10, but the reason he retired on his stool might have been due to some severe injuries.

Rigondeaux's manager Gary Hyde says that his fighter not only broke Amagasa's jaw in Round 9, but also his orbital bone the very next round.

"The Japanese crowd tore the house down in appreciation of an excellent fight and appreciation of Rigo's sublime skills," Hyde said. "It's an honour to be the manager of the greatest fighter in the world today."

Hyde told the WBO/WBA super bantamweight champion has an offer to fight in May.
