Hernandez (22-1, 19 KOs) applied increasing pressure and consistently tagged Kameda with straight shots, walking forward through resistance to score his second victory in two months.

98-92 and 97-93 scores in the 25-year-old's favor overruled a 96-94 card for the hometown fighter. The pair headlined 3150FIGHT 11 in-front of an intense yet intimate crowd at the Sumiyoshi Ward Center in Osaka, Japan.

This impressive win ensures the Mexican will navigate among elite names in a new weight class, having notably given Junto Nakatani all he could handle on the three-division champion's 122-pound debut last December.

Kameda (16-6-2, 9 KOs) began intently, working downstairs and moving plenty in the opening exchanges.

Hernandez was keen to match him and refused to take a backwards step, though both were prone to slipping and falling on the canvas in what quickly proved an action-packed affair.

Kameda pushed the pace well and mixed his shots well, whether uppercuts or hooks to the body, though the 25-year-old standing opposite him didn't seem fazed by the power coming back.

That was an important observation as Hernandez found a rhythm to his work in round three, upped the ante in the fourth and Kameda suddenly found himself having to counter and be reactive.

Almost defiantly though, Kameda landed two clean right hands flush on Hernandez's chin and a body shot in the final seconds of the fourth, as if to remind him this was far from over. Being fought at a frantic pace, the middle rounds were increasingly scrappy as they tagged one another with single shots.

Kameda found his second wind and fared better in the seventh, Hernandez unmoved as if those punches weren't having a cumulative effect. The body shot investments finally showed in the eighth as curling left hands and hooks briefly froze Hernandez. That visual proved a false dawn.

Kameda was roared forward to continue and potentially chain together a finishing sequence. Yet with a knockout percentage lower than 60 percent, he instead was guilty of overextending and losing his defensive shape.

Stung by jabs as Hernandez held his feet and turned the tide, both threw wildly but the Osaka resident looked like he was hanging on in the final frame. An entertaining watch, three-weight world champion John Riel Casimero had a front row seat and could potentially be next after his stunning fourth-round stoppage of Luis Nery in June.
