(Reuters) - Japan's Naoya Inoue became the second male boxer to be a four-belt undisputed champion in two weight divisions with a 10th-round knockout of Marlon Tapales in Tokyo on Tuesday.

Inoue unified the super-bantamweight titles of all four major sanctioning bodies, taking the WBA and IBF crown from Tapales and retaining the WBC and WBO belts he won in July.
