UFC 299 odds, predictions, start time, Miami fight card: O'Malley vs ...

Flamboyant bantamweight champion Sean O'Malley will get his coveted rematch against rival Marlon Vera on Saturday in the main event of UFC 299. Their five-round showdown anchors the main UFC 299 fight card starting at 10 p.m. ET from the Kaseya Center in Miami. In August 2020, Vera notched a first-round knockout of O'Malley, though the current champion has consistently discarded the result as due to an injury he suffered in the fight.

O'Malley is a -280 favorite (risk $280 to win $100), while Vera is a +230 underdog in the latest UFC 299: O'Malley vs. Vera 2 odds. The co-main event features former interim lightweight champion Dustin Poirier (+190) taking on rising prospect Benoit Saint Denis (-230).

UFC 299: O'Malley vs. Vera 2 preview 

O'Malley (17-1-1) is perhaps the most polarizing current champion on the UFC roster. Once dubbed a "permanent prospect" by a prominent MMA analyst, he has been criticized for both a risk-averse style and taking on a long slate of meager opposition before stepping up to tougher competition.  

His first fight against a ranked opponent resulted in the loss to Vera, and his second resulted in a no-contest against durable veteran Pedro Munhoz because of an eye poke from O'Malley. Somehow, he was paired against former champion Petr Yan, who was ranked No. 1 at the time, in his next appearance and won a disputed split decision at UFC 280 in October 2022. 

Even so, the 29-year-old Montana native, who is known for his massive following on social media, made the most of his subsequent title fight against Sterling by landing an overhand right to counter a Sterling takedown attempt and finished the fight with a flurry of punches. 

A rematch with Vera, 31, was long anticipated, though few MMA observers expected it to come in a title fight. 

Vera (23-8-1) is a 10-year UFC veteran known for his sinister disposition in the cage and relentless brawling style. The Ecuador-born fighter has had memorable battles against numerous top-tier opponents, and his resume includes knockout wins over former champions Dominick Cruz and Frankie Edgar. 

Following his win over O'Malley, Vera lost a five-round decision to former champion Jose Aldo but has since embarked on a run to win five of six and emerge as a title contender. You can see more UFC 299 picks at SportsLine.

UFC 299 predictions 

We'll share one of Vithlani's UFC 299 selections here: He is backing Gilbert Burns (+130) to pull the slight upset of Jack Della Maddalena (-160) in a matchup of welterweight contenders on the main card.

Burns (22-6) is a 10-year UFC veteran who is widely considered one of the most well-rounded fighters in the division. The 37-year-old Brazilian is a former multiple-time world grappling champion but also has lethal striking to complement his ground game. Burns is three years removed from a title shot in which he came up short against former champion Kamaru Usman. He has since gone 3-2 in five appearances.

Maddalena (16-2) is a straight-forward boxer who is known for his razor-sharp technique, but many observers wonder whether his one-dimensional style will hold up against world-class competition. The 27-year-old Australian is 6-0 in the UFC but has squeezed out split decisions in each of his past two outings.

"If Burns can get his hands on Maddalena and turn this into a grappling match, he will have a huge advantage. At plus-odds, I will take the seasoned veteran Burns to bounce back," Vithlani told SportsLine. You can see more UFC 299 picks at SportsLine.
