'Tired' Inoue beats Picasso by unanimous decision to end gruelling year
The fighter nicknamed "Monster" successfully defended his undisputed world super-bantamweight titles for the sixth time in his first fight in Saudi Arabia.
But it was not enough to knock out the gritty Picasso, as Inoue settled for a unanimous decision win for the second fight in a row.
The 32-year-old has had a jam-packed schedule this year and he blamed fatigue for a performance that he described as "not good".
"To be honest, I'm tired," he said, after taking his record to 32 wins, 27 by knockout.
