Andy Murasaki Submitted Every Opponent at Brasileiros — At Worlds He's the Most Dangerous Man Nobody Is Studying

Andrew Tackett called him boring. Then Andy Murasaki went to Brasileiros and submitted everyone.

Three matches. Three submissions. An arm-in Ezekiel over Gabriel Grinjo in the quarterfinals, a rear naked choke on Ethan Major in the semis, and an armbar on Felipe Ribas to take the lightweight gold at the 2026 IBJJF Brasileiros. That's what "boring" looks like on the results sheet.

Murasaki ran a sweep through one of the most competitive grappling fields in the world in São Paulo, adding the Brazilian national championship to a résumé that already includes No-Gi world titles and a European championship. He's 26. Currently the most decorated active lightweight in IBJJF competition. And depending on who you ask, too boring to watch.

What Tackett actually said

In late March, the UFC BJJ lightweight champion was asked about a potential matchup with Murasaki. Tackett's answer: "I don't want a boring fight." He elaborated: Murasaki's guard was nearly impossible to pass, and Tackett could see himself stuck there while Murasaki was perfectly fine with a one-point loss. He wanted someone with a different mentality—someone shaped by MMA culture at the UFC Performance Institute.

The someone he picked was Vagner Rocha. Rocha is 43 and on TRT. That match went to a decision.

So: the UFC BJJ champion passed on the eventual Brazilian national champion because his guard was too hard to pass and he didn't finish enough. Murasaki went to Brazil and finished everyone. The record stands.

The logic Tackett deployed—that a fighter who grinds, who controls space, who doesn't produce highlight reels—is somehow less dangerous—sits at the center of a broader misunderstanding about what separates elite jiu-jitsu from the rest. The sport has developed a strange hierarchy where stylistic preference masquerades as technical assessment. A fighter who finishes is somehow less desirable than one who generates drama. A guard that suffocates opponents is "boring" rather than precisely what wins matches at the highest level. Tackett's framing wasn't unique; it's the default narrative for any black belt whose game prioritizes efficiency over entertainment. The flaw in that thinking was on full display in São Paulo.

The technical case

Tackett isn't wrong, exactly. Murasaki's game is methodical. He pressure-passes with the patience of someone who will get there eventually, and it doesn't produce highlight moments until suddenly it does. His guard, the one Tackett found suffocating enough to book a different opponent, is among the best in the lightweight division.

What the "boring" label misses is what's happening underneath. Murasaki put away three opponents at Brasileiros with three different submissions from three different positions. An arm-in Ezekiel requires setting up and tightening in a way opponents often don't recognize until it's already over. The choke sits in the neck and shoulder space. The pressure builds asymmetrically. Most people escape because they see it coming. Murasaki's opponents didn't. A rear naked choke means he got to the back and finished from there, which isn't automatic at black belt. Getting to someone's back in modern jiu-jitsu against high-level opponents requires either devastating leg lock entries or superior positioning from top control. Once there, you're not guaranteed the finish either. People defend, frame, roll. At Brasileiros, Murasaki got there and finished. An armbar in a national final means the submission game held up under exactly the kind of pressure that collapses people. National finals are won by athletes who solve problems under maximum resistance. Murasaki's armbar did that.

He doesn't accumulate advantages and squeak out one-point wins. He finishes. That's a different athlete than the one Tackett described. The difference between a fighter who finishes at major tournaments and one who doesn't is the gap between someone who can execute under pressure and someone who can't. That's not boring. That's precise.

Consider what finishing three times in three matches means in context. The athletes Murasaki submitted weren't regional-level competitors. Grinjo, Major, and Ribas are all experienced black belts who've competed at absolute top levels. They're not there to be setup opponents. They're there to win. That they were all submitted means Murasaki's technical execution and positional control reached a level where escape became impossible. That's the opposite of boring. That's dominance expressed through technique.

Where he came from

Andy Murasaki was born in Saitama, Japan in 2000 to Brazilian parents of Japanese descent. He moved to the US at 15 to train jiu-jitsu, starting with Caio Terra's team before landing at Atos in San Diego. André Galvão promoted him to black belt in December 2020. He's now with Art of Jiu-Jitsu (AOJ).

His black belt career started at EUG, featherweight gold in his debut. The featherweight title was significant; it came immediately, without years of grinding in the lower belts first. Then came the European championship, the No-Gi world championship, the Spyder Invitational victory at 75kg after a weight class drop he made to play faster and more aggressive. He reached the 2024 IBJJF Worlds lightweight final and lost to Mica Galvão, who comes back in June as the defending champion.

That loss was eighteen months ago. In the span between that final and Brasileiros, Murasaki was training, competing, adjusting. The IBJJF system doesn't reward evolution the way MMA commentators like to describe it. You don't get press releases for solving problems in the lab. You get them when you show up at a major tournament with answers. Brasileiros was the answer. Three submissions. Three different positions. One weekend.

The Worlds problem

IBJJF Worlds is in June. The lightweight black belt field will be loaded. Galvão returns as champion. This is the hardest bracket Murasaki has faced since that 2024 final.

His name will be on it. Whether his opponents have spent real time preparing for him is the actual question.

This is where Murasaki's trajectory becomes genuinely interesting as a competitive problem. The athletes who get studied are the ones generating attention: callouts, feuds, viral clips, podcast appearances, the entire apparatus of modern combat sports visibility. Murasaki doesn't do any of that. He doesn't call anyone out. He doesn't generate feuds. He submits people at major tournaments and the results sit on the results page for anyone who bothers to look.

The problem with that approach is simple. In a sport where preparation is everything, where matchup-specific game plans matter, where time spent studying an opponent's typical entries and escapes can be the difference between winning and losing—being ignored is a competitive advantage only until you reach the level where everyone is studying everyone.

At Worlds, that level is here. But the question isn't whether Murasaki will be studied. It's when that studying started. If it started last week, after Brasileiros, his opponents are behind. They're reacting. If it started months ago, if his name was already on lists of problems to solve, then his advantage disappears. That's the only real variable.

The gap between his name recognition and his résumé isn't about talent. It's about how a sport with a drama-driven media ecosystem hands out attention. He doesn't generate drama. He generates submissions. Brasileiros: three of them in one weekend.

The irony on record

The UFC's grappling arm had the chance to book him. Its champion passed, citing his guard and his comfort with grinding losses. The match that got booked instead went to a decision. A decision against a 43-year-old competitor on TRT. That's the recorded outcome.

Anyone not preparing for Murasaki at Worlds is running the same logic Tackett ran: he doesn't create drama, he doesn't finish fast enough for entertainment purposes, his game is suffocating rather than spectacular. That logic might hold. Or it might cost someone a gold medal in June.

The Brasileiros scoresheet suggests which version is more likely.

He submitted everyone. Nobody's talking about it. He's fine with that. But indifference to media attention doesn't mean indifference to results. Murasaki came to São Paulo to prove something. He did. The question now is whether the jiu-jitsu community will notice before it matters.
