The bout started as we expected, with Aso applying pressure from the off and forcing Okada to box off the back foot with sharp jab and uppercuts being used as clever counters. Those counters were racking up the rounds for Okada, who was widely ahead on the scorecards after 5 rounds, and having an effect on Aso's face with cuts opening up as a result of the clean shots from the champion. Despite being cut Aso refused to change tactic, knowing his best defense was his offense and he continued to try and wear down the champion with his intense pressure and body shots.
The damage to Aso's face worsened in rounds 6 and in round 7 the doctor had seen enough, calling a halt to the bout to give Okada his most impressive stoppage win so far.
For Aso the result was a disappointing one, but the performance suggests he could come again. For Okada it's perhaps time to give up the Japanese title and look to claim the OPBF title, with a fight against Al Rivera being a very promising match up on paper.
