Pre-fight analysis

Demopoulos has lost three straight and gives away twelve centimetres of reach; Jauregui hasn't fought in two years and was knocked out in twenty seconds the last time someone touched her clean.

Vanessa Demopoulos is 37, has lost her last three, and is 5-5 in recorded fights. Yazmin Jauregui is 27, has not competed since September 2024, and is 3-2. Neither is arriving in good shape, and the fight is interesting mostly because their weaknesses are so precisely opposite. Jauregui is the striker, and it is not close: a 4.53 striking score against Demopoulos's 1.00, with 4.13 pressure agains…

Demopoulos intel

Demopoulos (11-8) has lost three in a row — Jamey-Lyn Horth in June 2025, Talita Alencar in April 2025, and Jaqueline Amorim by first-round submission in September 2024. At 149.9cm her reach is among the shortest in the division and her 1.00 striking score reflects it.

Jauregui intel

Jauregui (11-2) has not fought since being submitted by Ketlen Souza in the first round in September 2024 — two years out. Her best win is a decision over Iasmin Lucindo, rated 53.8, in August 2022, and Denise Gomes knocked her out in twenty seconds in July 2023.

Key angles

A 12.7cm reach gap at strawweight, which is close to a division-record disparity

Jauregui's 0.00 submission score against a fighter who scores 2.00 — and her own last fight was a submission loss

Two years out of competition for Jauregui

Demopoulos's three-fight losing run at 37

Jauregui's 66.0 chin and the twenty-second Gomes knockout still on the record

Risk flags

Ring rust in a fight decided by distance management is a heavier cost than the ratings show

Demopoulos cannot hurt Jauregui standing, so if the takedowns fail she has no second plan
