ONE Championship video: Demetrious Johnson submits Yuya Wakamatsu in debut

Demetrious Johnson was victorious in his ONE Championship debut on Sunday.

The former UFC flyweight king was matched up against Yuya Wakamatsu in a flyweight grand prix quarter-final bout at ONE: New Era in Tokyo, Japan, and got the finish in the second round. After a competitive opening round, “Mighty Mouse” went for a takedown and worked on a choke from the mount, but Wakamatsu was able to fight it through.

Seconds later, Johnson took advantage of the different ruleset to land a few knees to the head of a grounded Wakamatsu before locking in a guillotine choke that forced the 24-year-old Japanese fighter to tap in Tokyo.

”I love the knees to the grounded opponent,” Johnson said after the win. “I just kept on reaching and I got a real nice guillotine. He went for the shot, I put my hips in and he was hanging on to my leg and I gave it more of a torque to get that finish. I don’t know if he went out or not because he tapped and then he woke up and was like ‘what happened, what happened?’ Can’t wait for the next round.”
