Montserrat Rendon Record: 7-2-0

The UFC arrival

Rendon made her UFC debut in September 2023 against highly regarded prospect Tamires Vidal, edging the Brazilian by split decision in a hard-fought three rounds to validate her arrival on the big stage. The momentum stalled in March 2024 when she dropped a unanimous decision to unbeaten Russian Darya Zheleznyakova, her first loss inside the Octagon and a reminder of how thin the margins are at the elite level.

Bouncing back and a setback

Rendon rebounded in September 2025 with a split-decision win over previously undefeated Alice Pereira, again showing her knack for surviving the championship rounds and landing on the right side of close cards. In March 2026, though, she ran into a grappling problem of her own, submitted by rear-naked choke in the first round by unbeaten Bia Mesquita – a rare early finish on a résumé otherwise defined by going the distance. Earlier in her career she had also tasted a submission loss to Juliana Miller in a 2021 combat jiu-jitsu bout, a reminder that even an accomplished grappler can be tested on the mat.

Fighting style

Rendon is the definition of a decision fighter – all seven of her professional wins have come on the scorecards, a 0% finish rate that reflects a patient, volume-and-control approach rather than a hunt for the knockout. Her foundation is jiu-jitsu, and her best path to victory runs through clinch work, positional grappling and the ability to bank rounds and survive late, as her repeated split decisions show. The flip side is finishing power: she rarely threatens the stoppage, and her two professional losses have both come by way of submission, suggesting that elite grapplers who can reverse the script remain her toughest stylistic matchup.

Career highlights
