Yamamoto’s Wrestling Shuts Down Ito in RIZIN Reserve Bout
Erson Yamamoto defeated Yuki Ito by unanimous decision at RIZIN.51 on September 28, 2025, in Nagoya, Japan. Their three-round flyweight contest was a Grand Prix reserve match, and all three judges awarded it to Yamamoto.
Repeated takedowns shape the fight
Ito attacked quickly at the opening bell, but Yamamoto avoided the early threat and turned to his wrestling. Ito initially got back up, only for Yamamoto to stay attached and return him to the ground.
That pattern continued in the second round. Yamamoto absorbed striking exchanges while pursuing clinches and takedowns, then worked behind Ito when opportunities developed. Ito kept trying to stand and reestablish distance.
Yamamoto closes without surrendering control
Ito defended two takedown attempts in the final round, but Yamamoto completed another entry after driving him toward the corner. Ito threatened with a triangle from underneath; Yamamoto prevented the finish and continued controlling the exchanges. The unanimous decision gave Yamamoto the reserve position rather than a place earned through a regular tournament quarterfinal.
