Patchy Mix RIZIN 54 ended in his fourth straight loss on Tuesday. Mix entered the bout already facing a two point penalty. He had missed weight by more than six pounds the day before. The result extends a brutal fall for a fighter once ranked among the sport’s best.

What Happened
Mix faced Shoko Sato in Tokyo on Tuesday, August 11, 2026. He missed the bantamweight limit by 6.28 pounds at the official weigh in. RIZIN rules impose an automatic two point deduction for misses beyond 0.5 kilograms. Mix could not even earn an official win under these terms.
Sato took the fight on the scorecards by unanimous decision. The loss marks Mix’s fourth defeat in a row across two promotions. His once promising comeback bid inside RIZIN now sits in serious jeopardy after the setback. Fans and analysts reacted with real concern over his continued decline.
Key Details
Mix weighed in at 140.8 pounds against a 134.5 pound limit for the bantamweight bout. That gap forced RIZIN to demote the fight from its planned co main event slot. Any win by Mix would have been ruled a no contest under promotion rules. He also forfeited part of his fight purse as a penalty.
Mix said illness disrupted his weight cut in the final days before the bout. He thanked Sato for accepting the fight despite the unusual terms attached to it. Sato treated the short notice opportunity as a real chance to prove himself. This was the first time in his career Mix missed weight.

What This Means
This defeat pushes Mix to a four fight losing streak across two organizations. He has not won a fight since leaving the UFC roster earlier this year. The pattern raises real questions about his future inside the cage.
Weight cutting issues rarely disappear on their own without a change in approach. Mix will need a clear new plan to avoid a fifth straight loss. His camp faces real pressure to address the pattern before it costs him further opportunities.
Background Context
Mix once looked like one of the top bantamweights on the planet outside the UFC. He built a record of 20-1 during his run with Bellator. That stretch included a win over Kyoji Horiguchi and the Bellator bantamweight title.
The UFC signed Mix last year as one of its most anticipated bantamweight additions. He lost his promotional debut to Mario Bautista by unanimous decision at UFC 316. A split decision loss to newcomer Jakub Wiklacz then ended his brief UFC run.
Mix then joined Japan’s RIZIN promotion after his UFC release. He lost his debut there to Kyoma Akimoto by knockout in March. The defeat to Sato at RIZIN 54 extends that skid to four straight losses.
Final Thoughts
Patchy Mix now carries real pressure into whatever comes next in his career. The weight miss and four fight skid have badly damaged his once elite standing. Fixing the pattern will matter more than any single result going forward. His next move could define whether he can turn this slide around.
