“I was ready for everything” - Diogo Reis reacts to world title win over Daiki Yonekura at ONE Fight Night 38

Diogo Reis claimed the vacant ONE flyweight submission grappling world title at ONE Fight Night 38 inside the Lumpinee Stadium this past Friday, December 5.

The Brazilian ground game specialist delivered a 10-minute grappling clinic to take home a deserving win over tough Japanese contender Daiki Yonekura in Bangkok, Thailand.

He reflected on his triumph and analyzed his winning strategy during his post-fight in-ring interview with Mitch Chilson, admitting that his foe's ultra-tough defense made him put in extra work during fight camp.

"[There weren't] any surprises, I was ready for everything. I knew [Daiki Yonekura] was a good opponent, so I still prepared myself for this, you know, I'm so tired here because I gave him my all to get this title. So that's what made it better," the Melqui Galvao product shared.

The two-time ADCC world champion brought his aggressive mount game to unsettle the Tokushima native, who was happy to let Diogo Reis hunt for openings from guard.

It was all gas and no brakes throughout the tie, and in the final stretch, both warriors were tied up in a scramble, looking for leg entanglements while forcing one or the other to give an inch.

Neither Brazilian jiu-jitsu black belt, however, showed any cracks. And after an entertaining 10-minute contest, 'Baby Shark' deservingly left the ring inside the Mecca of Muay Thai as the new ONE flyweight submission grappling world champion.
