From the opening round Iwasa looked sharp and oozed confidence, he also looked like a man who was more fluid than we'd typically seen him. That fluidity saw him unloading some beautiful combinations that saw him switch from head to body with ease and Tubieron was forced to soak up the punishment.
To his credit Tubieron did try and fight back at times, soaking up the pressure before firing out wild right hooks, several of which caught Iwasa but had little real effect on the Japanese fighter who continued to land at will. Sadly for Tubieron the aggression of Iwasa forced him to the ropes regularly where he was able to unload the combinations, which were always punctuated by sicking left hands to the body.
That left hand to the body seemed to be something Iwasa was consciously working on and it paid off very early, hurting Tubieron with the shot early in the fight. The Filipino saw out the trouble, but in round 7 he was caught by another left to the body, on the counter, as he looked for one of his wild shots. This time he was sent down where he remained for the count.
Following the bout Iwasa stated that his intention was to get a world title at Super Bantamweight. On this performance it's fair to say he is more suited to the 122lbs weight class than the Bantamweight division, which he had been struggling with for several years, though whether he picks up a world title is a whole different question.
For Tubieron his guts were on show again, but he was out classed and will surely be given a bit of a break from hard fights following a 5 fight win-less streak.
