WBO super flyweight champion Naoya Inoue made his U.S. debut in style Saturday, hammering seventh-ranked Antonio Nieves by a sixth-round technical knockout to defend his title for the sixth time.
Inoue, 24, controlled the bout from the outset, knocking his 30-year-old American opponent down in the fifth and didn't let up the following round.
After the sixth, having seen enough, Nieves' corner threw in the towel. All three judges had Inoue comfortably ahead 60-53 through the sixth at StubHub Center.
