Alvarenga Doubles Down at ONE, Yoshida’s 15th F2W Defense | No-Gi Weekly Aug 17–23, 2026

Welcome to No-Gi Weekly — your Saturday roundup of the most important submission grappling news, results, and announcements. This week: Ruan Alvarenga moved to 2-0 over Meyram Maquine on the ONE Championship stage; Baret Yoshida posted his 15th Fight to Win title defense in Hawaii; the ADCC Youth Worlds put the next generation under the spotlight in Austin; and off the mat, UFC BJJ confirmed its most crossover-friendly main event yet while the Kraków countdown tightened with Duarte vs. Simoes locked in as the ADCC Superfight.

1. Ruan Alvarenga Goes 2-0 Over Maquine at ONE Fight Night 46

Ruan Alvarenga made it two for two against Meyram Maquine Alves at ONE Fight Night 46 on August 14, 2026 from Lumpinee Stadium in Bangkok, Thailand. The featherweight submission grappling rematch went the distance, with Alvarenga taking the unanimous judges’ decision.

Their first meeting came at BJJ Stars 17 in 2025, where Alvarenga also won on the cards. Friday’s rematch saw Alvarenga dictate the pace from the opening exchange — arm-dragging Maquine back to the mat, advancing from half guard to closed guard and then to side control with consistent pressure. Neither competitor landed a match-ending submission, but Alvarenga’s positional aggression was decisive enough to earn all three judges.

The win confirms Alvarenga as the dominant competitor in this rivalry and pushes him toward bigger opportunities in ONE Championship’s growing submission grappling division. The FloGrappling–ONE Championship partnership announced earlier this summer has significantly elevated the profile of grappling bouts on ONE cards — and Alvarenga is emerging as one of the clearest beneficiaries of that increased exposure at featherweight.

ONE Fight Night 46 also featured a full card of MMA and Muay Thai, with Stella Hemetsberger defending the flyweight Muay Thai title and Nico Carrillo picking up a knockout win. For the no-gi audience, Alvarenga’s grappling bout was the headline.

2. Baret Yoshida’s 15th F2W Title Defense: Triangle in Hawaii

One day after ONE Fight Night 46, Fight 2 Win 323 landed in Hawaii on August 15 — and Baret Yoshida was at his ceremonial best. The Hawaiian grappling legend submitted Nick Alcoran with a triangle choke in the main event, marking his 15th consecutive title defense at F2W.

Yoshida, known widely as “The Finisher,” has built one of the most consistent no-gi records in professional grappling through his mastery of unorthodox submissions — the assassin choke (a crucifix-based neck crank) being his signature — but he showed his submission range is far wider than any one technique. The triangle finish over Alcoran was clean and definitive.

Fifteen title defenses at a single promotion is a remark few professional grapplers can match. F2W Hawaii events have long drawn elite local talent and visiting competitors from the mainland, giving Yoshida a home-crowd backdrop that matches the longevity of his run. His submission rate across those 15 defenses remains extraordinary, and at no point has the title felt like a formality.

For anyone preparing for no-gi competition in Hawaii this fall — or researching triangle choke setups — Yoshida’s F2W run is one of the most instructive tape studies available. The full event replay is available on FloGrappling.

3. ADCC Youth World Championship 2026: The Next Generation Has Arrived

The second-ever ADCC Youth World Championship took place August 9 in Austin, Texas — and the results point clearly toward where elite no-gi grappling is heading. With 304 competitors from 110 academies across 272 decided matches, the event delivered a 58% submission rate (compared to the adult ADCC average of 67%), which is striking for competitors aged 7 through 17.

Art of JiuJitsu (Costa Mesa, CA) dominated the team standings with 10 gold medals and 16 total medals. Steven Ortiz, a yellow belt from AoJJ with a rating of 8,448, was the standout performer of the event — a name to track as the next ADCC adult cycle approaches.

What ADCC Youth Worlds does that no other event replicates is give you an early look at the competitors who will be fighting for ADCC open spots in 2028 and 2030. The 2022 and 2024 ADCC Worlds produced results that no one fully predicted — Youth Worlds is where the next wave starts. The 58% submission rate, even slightly below adult level, confirms that elite no-gi instincts are being developed younger and faster than ever.

Dig into the bracket results and a consistent pattern emerges: academies running dedicated no-gi programs outperformed larger gi-first programs across multiple age categories. The bracket structure mirrors adult ADCC closely — weight divisions, time limits, and the overtime format that defines the parent event. Young competitors are not just learning techniques; they are learning the pacing, the positional strategy under submission-only rules, and the late-match pressure management that separates elite no-gi grapplers from strong gi competitors who occasionally show up at no-gi tournaments.

The gear standard is worth tracking for anyone following the commercial side of the sport. ADCC Youth runs rashguard and shorts only — no gi, no belt. Every competitor at this event trains and competes exclusively in no-gi equipment. A generation building mat time in rashguards from age seven does not pivot to gi when they reach adult competition. They arrive in open divisions and professional circuits with no-gi instincts already hardwired. That is a different consumer profile than traditional BJJ — one that puts no-gi gear at the center of the sport rather than as a supplement to gi training. Youth Worlds is where that shift compounds annually.

4. UFC BJJ 11 Announced: Mikey Musumeci vs. Bryce Mitchell, September 24

The biggest no-gi crossover announcement of the year dropped this week: Mikey Musumeci vs. Bryce Mitchell headlines UFC BJJ 11 on September 24, 2026, at Meta Apex in Las Vegas.

The details: the bout is at featherweight, which means Musumeci’s UFC BJJ Bantamweight title is not on the line. Mitchell — a UFC featherweight and bantamweight contender with deep BJJ roots — becomes the first active UFC fighter to face a UFC BJJ champion in a non-title contest. The announcement sent immediate ripples through both the UFC and grappling communities.

Musumeci’s UFC BJJ record stands at 4-0, all by submission: three heel hooks and one foot lock. That finishing rate is precisely why Mitchell’s participation is compelling — Mitchell’s BJJ credentials within MMA are genuine (triangle chokes, kimuras), but surviving Musumeci’s leg lock game from the feet is a different problem entirely. The contrast in styles makes this one of the more unpredictable no-gi matchups of 2026.

In the co-main event, UFC BJJ Light Heavyweight champion Mason Fowler defends his title against Nick Rodriguez — himself a former ADCC silver medalist who has stayed sharp in no-gi competition. The full card around these two bouts should be worth clearing your schedule for on September 24.

5. ADCC Kraków: Duarte vs. Simoes Superfight Is the Main Event the Sport Needed

With three weeks until the mats go down in Poland, the ADCC 2026 World Championships at Tauron Arena in Kraków (September 12-13) are crystallizing around one matchup: Kaynan Duarte vs. Yuri Simoes for the vacant ADCC Superfight title.

Gordon Ryan vacated the belt in February 2026 due to persistent health issues — the first time the Superfight title has been vacant in 17 years. Duarte earned his shot by winning the absolute division at ADCC 2024. Their history adds stakes: Duarte defeated Simoes 3-0 on points at ADCC 2019, and Simoes went on record this week telling FloGrappling he is “ready to dominate” in the rematch. Neither man is giving the other any pre-event ground.

Duarte competes for Atos Jiu-Jitsu; Simoes for Checkmat. Both are absolute-division caliber heavyweights — physical, technical, and capable of winning by submission or accumulated advantage. In a post-Ryan landscape, the winner of this Superfight steps into a genuine power vacuum.

The wider 128-man bracket includes notable absences: Kade Ruotolo, Tye Ruotolo, Nick Rodriguez, Mica Galvao, Giancarlo Bodoni, and Izaak Michell are all out. On the additions side, Gabi Garcia returns in women’s super heavyweight, and UFC fighter Mateusz Gamrot enters the lightweight bracket. The full confirmed field makes Kraków the most wide-open ADCC bracket in recent memory.

Looking Ahead

The final stretch of summer grappling is stacked. Here is what to mark on your calendar:

• August 29 — ADCC Uberlândia Open (Uberlândia, Brazil, live on FloGrappling): A regional ADCC open under full submission rules. Expect competitors using this as a final competitive sharpener before Kraków.
