From the opening seconds, the match established its terms: Iwamoto on top, Leon underneath, entirely at ease there.
Iwamoto pushed forward early, forcing his way into Leon’s guard and trying to settle heavy pressure. Leon answered immediately, showing why opponents hesitate to engage him there. His movement was constant, legs threading, inverting, spinning, at times closer to a breakdancer than a grappler.
Iwamoto read the leg entries and rotated with him, managing to stay on top, but passing was another matter. Leon’s guard shut down forward progress, forcing resets without giving up position.
As the pace leveled out, Leon expanded his attacks. He slipped underneath pressure, entered leg entanglements, and clamped onto the Achilles, pulling Iwamoto into defense. Any attempt to build offense stalled before it started.
Midway through the round, there was a brief pause when Leon’s toe caught in Iwamoto’s shorts during an exchange. The referee intervened, untangled them, and restarted the match.
Iwamoto went back to pressure, folding the legs, working double unders, and stepping on Leon’s limbs to flatten him. It echoed the approach Tairu Tolo had used before, but Leon adjusted. Each attempt ran into a well-timed knee shield, his left leg posted high across the shoulder, stopping entries before they developed.
Around the four-minute mark, Iwamoto began to show the cost of that pace. He had spoken about forcing his cardio on opponents, but here he was the one spending. Leon stayed measured, giving little away while continuing to threaten.
Leon cycled through positions, bringing in X-guard, off-balancing Iwamoto and forcing him to react. The defenses held, but they never turned into offense.
With under two minutes left, the match opened up.
Leon attacked the arm, inverted, and came up into a triangle. The transition never paused, shifting between arm control and the choke until his legs locked tight around Iwamoto’s neck and shoulder.
They drifted toward the ropes in the scramble, limbs tangled to the point the referee had to step in and reset them in the center.
Leon kept the triangle on the restart, pulling the head down and tightening. For a moment, it looked close.
Iwamoto forced his way out as time ran off the clock, escaping the most dangerous sequence of the match. The horn sounded with both men spent.
Without a finish, it went to the judges. Leon dictated the match from bottom, threatening throughout with leg attacks and the late triangle, while Iwamoto never passed or built a submission of his own.
All three judges gave it to Dante Leon by unanimous decision.
