Vegas Vendetta: UFC Returns to the Meta APEX for Raul Rosas Jr. vs. Raoni Barcelos

UFC 331 could have been a monster night, but a few let-down spots, and we came away with just under 2 units. While we’re hovering around that +20 Unit mark, it’s been taking some time for us to cross that threshold.

Next up is UFC  Vegas 121, a return to the UFC Meta APEX for a showdown between Raul Rosas Jr. and Raoni Barcelos. In what is a surprising co-main event, Rodolfo Vieira takes on Robert Bryczek. Let’s take a look at the rest of the main card, and don’t forget to check back later in the week for our UFC Vegas 121 best bets.

UFC Vegas 121 Main Card Breakdown

Brady Hiestand

3.85

1.27

Rinya Nakamura

Brady Hiestand brings a gritty, high-volume wrestling style backed by relentless cardio and opportunistic submission skills. The former TUF finalist thrives on dragging opponents into high-paced scrambles, utilizing non-stop forward pressure and level changes to break down his opposition over three rounds. While his strike defense can leave openings, his durability and tenacity make him extremely difficult to put away once he establishes top control.

Rinya Nakamura is an elite freestyle wrestler whose background is complemented by blistering hand speed and explosive, southpaw striking. With extraordinary takedown accuracy and defense, Nakamura uses his wrestling background defensively to keep fights standing or land brutal ground and pound. His sharp power punches and dynamic kicks give him dangerous early-finish potential against anyone willing to trade shots.

The fight centers on whether Hiestand can make Nakamura bleed for his cardio or if Nakamura’s superior credentials neutralize Hiestand’s grappling. Hiestand’s best route to victory is to force early clinch battles to drain Nakamura’s explosiveness and pull him into deep waters. However, Nakamura’s world-class takedown defense and sharper striking optics give him the tactical edge, making a dynamic counter-striking knockout or dominant decision his most probable path to victory. 

Melissa Amaya

2.80

1.45

Valesca Machado

Melissa Amaya enters this strawweight bout with a dominant grappler’s skill set and high-level finishing ability. Known for her relentless wrestling, smothering top position, and tight submission transitions, Amaya excels at taking opponents down early and controlling the canvas. While her striking on the feet is still improving, her continuous forward pressure and ability to dictate grappling exchanges make her a formidable threat.

Valesca Machado brings battle-tested experience, explosive striking, and sharp Muay Thai. Operating with crisp boxing combinations, low leg kicks, and strong defensive counter-punching, Machado tries to keep the fight standing where she can out-volume her opponents. She tries to maintain distance and utilize strong takedown defense to avoid getting trapped along the fence.

This fight presents a direct striker-versus-grappler dynamic where space and cage control decide the outcome. Machado’s path to victory depends on her strict lateral movement and sharp counter-strikes to deny Amaya’s initial entry attempts. However, Amaya’s superior wrestling pedigree and relentless chain-takedowns give her the tactical edge, making a control-heavy decision or submission her most probable routes.   

Mehemmedeli Osmanli

1.34

3.35

Ilimbek Akylbek Uulu

Mehemmedeli Osmanli brings a powerful physical presence and aggressive heavy-striking, relying on early momentum to overpower opponents. Known for his explosive right hand and aggressive forward pressure, Osmanli looks to establish control early and push a high-tempo pace. While his striking yields high knockout potential, his high-energy style can leave defensive gaps, testing his cardiovascular endurance if the fight gets into later rounds.

Limbek Akylbek Uulu is a methodical, well-rounded fighter whose game relies on durable wrestling, grinding top control, and relentless grappling pressure. Uulu excels at closing the distance, trapping opponents along the fence, and systematically breaking them down with heavy ground control and smothering scrambles. His durability and wrestling background allow him to survive early storms and drag aggressive strikers into deep, exhausting waters.

The matchup features a battle between Osmanli’s early explosive striking and Uulu’s grinding wrestling. Osmanli’s clearest path to victory relies on catching Uulu during initial entries with a fight-ending power shot before his cardio gets tested. However, Uulu’s superior grappling control and steady pace give him the structural advantage to weather the early exchanges, secure the canvas, and earn a late-round stoppage or ground-heavy decision victory.   

Rodolfo Vieira

1.61

2.36

Robert Bryczek

Rodolfo Vieira is a decorated multi-time Brazilian Jiu-Jitsu world champion, possessing some of the most dangerous and fluid submission skills. Known for his smothering top pressure, guard passes, and lethal arm-triangle chokes, Vieira looks to secure immediate takedowns to turn every fight into a grappling clinic. While his striking and gas tank have historically shown defensive vulnerabilities under pressure, his ability to force mat scrambles makes him an instant threat whenever the fight hits the canvas.

Robert Bryczek is an experienced striker who relies on explosive boxing, heavy power hooks, and precise distance management. Carrying dangerous knockout power in both hands, Bryczek operates best when keeping opponents on the outside and catching aggressors as they attempt to close the distance. His entire game plan hinges on maintaining a solid defensive stance, avoiding the mat, and utilizing sharp takedown defense to keep the action standing.

The matchup presents a classic striker-versus-grappler dynamic where spatial management will dictate the winner. Bryczek’s primary path to victory lies in utilizing his 75-inch reach and explosive counter-punching to stop Vieira’s entries and land a early fight-ending knockout. However, Vieira’s world-class grappling credentials give him a massive structural edge on the mat. If he can dodge Bryczek’s heavy strikes, drag the power-puncher to the canvas, and establish top control, a submission or ground-and-pound stoppage is his most probable outcome. 

Raul Rosas Jr.

1.58

2.42

Raoni Barcelos

Raul Rosas Jr. enters this bantamweight clash as a phenom whose game centers on aggressive chain-wrestling, relentless body lock entries, and high-level back-taking ability. Rosas Jr. thrives when he can smother opponents against the fence, break their posture, and initiate back-scrambles for submission finishes. While his striking and cardio pacing have matured, his main tactical strength remains dragging fights into immediate, high-volume mat sequences.

Raoni Barcelos is a seasoned veteran who brings high-level Brazilian Jiu-Jitsu credentials alongside explosive, crisp boxing. Renowned for his stout takedown defense, heavy counter-punching, and sharp footwork, Barcelos excels at denying entries and forcing opponents to pay for rash level changes.

This bout comes down to Rosas Jr.’s non-stop grappling pressure and Barcelos’ veteran defense and sharp counter-striking. Barcelos’ best route to victory is using his footwork to keep the fight in open space, catching Rosas Jr. with crisp upper-body counters as he shoots, and punishing any sloppy entries. However, Rosas Jr.’s continuous wrestling pressure, relentless back-mount threats, and cardio give him the edge to secure top control, and claim a decision or late submission victory. 

UFC Vegas 121 Best Bets

2025 Total Units Won: +29.97 Units

2026 Record: 75-88-1, +17.14 Units

(Every bet is 1 Unit unless specified)

Mehemmesdeli Osmanli to Finish @ 2.15 (1.5 Units)

Osmanli is one of the more exciting prospects on the rise, and he’s taking on a wrestling-heavy and chinny fighter in Akylbek. He should be the better athlete with far more skills and power on the feet. He will be hunting for a big finish.

Luis Hernandez to Finish @ TBD (1.5 Units)

We’re not getting a price on this yet, but anything better than 1.60 is a must-take. Luis Hernandez is coming right off DWCS and is poised to make a splash in the UFC. Lucky for him, he takes on a Sedrique Dumas, a fighter who struggles to find success consistently and gets in his own head.

Elvis Brenner FINISH ONLY @ 1.86

Josiah Harrell is moving down in weight and coming off serious health concerns. That seems like a terrible combination, especially before going into a fight against Elvis Brenner. Instead of taking the moneyline and losing a close decision, the finish-only line makes sense here. If this goes to a decision, we get our money back, but Brenner has the power and pressure to put someone like Harrell away.

Raoni Barcelos to Win @ 2.40

Barcelos is definitely on the tail end of his career, but that seems to be where he’s doing his best work. This isn’t the best matchup for him, but he should have a striking edge and a cardio advantage if Rosas Jr. struggles to keep him down. He’s been the prospect killer before, and this is another opportunity for him to steal some thunder.

John Castaneda to Win / Rodolfo Bellato to Win @ 1.99

John Castaneda is a well-rounded fighter with good durability and cardio. This is a good matchup for him where he should be able to do more than Alatengheili and take a dominant decision.

Rodolfo Bellato is such a hard fighter to trust, but Christian Edwards struggles with durability, and Bellato has solid power for the division and always pushes the pace.

UFC Vegas 121 is a far cry from UFC 331, but there are plenty of fighters looking to prove themselves, and that always makes for competitive fights. The main event is a solid test for Raul Rosas Jr., while the rest of the main card features new, exciting, fighters. The prelim fights should hold up their weight, which can only add to an underrated fight night.
