Undisputed super bantamweight champion Naoya Inoue outpointed Alan David Picasso on Saturday to set up a potential pound-for-pound super fight with Junto Nakatani.
Three-weight world champion Nakatani also beat Sebastian Hernandez Reyes on points on the card in Saudi Arabia after making his debut in the division.
The two victories set up a much-anticipated clash in 2026 that would be the biggest fight in Japanese boxing history.
