De Souza Submits Last Week’s Star in a 5,550-Jits Upset

Vinicius De Souza enters Newbreed Mid Florida rated 2,810 Jits. He exits at 5,130 after going 6-0 with all six wins by submission. The headline result — catching Alex Lee Trejo at 8,360 Jits — is a 5,550-Jits gap, the widest upset across all fourteen tournaments this weekend.

Grace Keeler has an interesting weekend at AGF Springfield. She takes gold but also appears on both the MVP and the upset-victim lists — Abigail Cummings submits her in a 4,610-Jits gap before she recovers.

Grappling Industries Detroit produces the deepest brackets of the weekend. Mason Thomas Mahlock of LEAD BJJ runs two separate six-win brackets in different divisions. Justus Slusher of Unity Jiu Jitsu Grand Rapids, Mitchell McMurray of Iron and Soul Jujitsu, and Arber Dembogaj Beyer of RCC each go six deep as well. McMurray's run is notable — he breaks Mitchell McMurray's own 18-win streak in the same tournament.

At Grappling Industries New Jersey, Terran Sarmiento of Round Table BJJ wins six straight for the second consecutive weekend — he did the same at DMV last week. Roman Tenorio of Crown BJJ runs six deep at United Grappling Salt Lake City.

Three upsets above 4,500 Jits this weekend, all by submission. The top two both break the 1% win probability barrier.

On the streak-breaking front: Nathan Reyes (37-0) falls to Armenak Garayan at NAGA Los Angeles II. Aubrey Coppini (35-0) drops to Ellisa Erica Nieves at JJWL San Diego XVII. Yasin Abdelrasoul (33-0) loses to Rowan Giaretta at Newbreed Chicago. Three more 30-plus streaks gone. September took the 50-win runs; October is clearing the 30s.

Art of Jiu Jitsu posts the most striking ratio of the weekend: 26 golds from 43 fighters — a 60% gold-to-medal rate and a 67% gold rate relative to total medals. KDMMA runs 22 golds from 29 fighters at NAGA Los Angeles II. Pablo Silva BJJ leads in raw volume with 63 medals across the JJWL Austin double-header.

Vinicius De Souza gains +9,110 Jits on a perfect 6-0 weekend at Newbreed Mid Florida. Six wins, all submissions, and a jump to 4,394 Jits — the biggest single-weekend Glicko-2 move across all fourteen tournaments.

Artur Landkof follows with 5-0 and +8,550 Jits. Sérgio Almeida goes 6-0 for +8,260 Jits and reaches S-Tier at 7,326 Jits. On the drops side, Alex Lee Trejo takes the hardest fall: -4,660 Jits on a 1-3 weekend — a complete reversal from his +7,360 Jits gain two weeks ago.

Risers

Drops

Alex Lee Trejo's arc tells the story of October's first weekend. A +7,360 Jits gain in September. A -4,660 drop in October, kicked off by a submission loss to a fighter rated 5,550 Jits below him. The Glicko-2 system is honest — it remembers everything and forgives nothing. Three more 30-plus win streaks fell this weekend, continuing the September-October correction that has now claimed twelve such streaks in three weeks.
