UFC Sacramento: Anthony Hernandez vs Gregory Rodrigues continues on the main card with the co-main event between Serghei Spivac and Vitor Petrino in the heavyweight division. Check out our UFC Sacramento odds series for our Spivac-Petrino prediction and pick.

Serghei Spivac (18-6) enters on a high note, having bounced back with a unanimous decision win over Ante Delija in February 2026. That victory snapped a two-fight skid that included a decision loss to Waldo Cortes-Acosta and a brutal first-round TKO defeat to Jailton Almeida in January 2025. The “Polar Bear” now looks to build momentum as he comes into this fight this weekend against Vitor Petrino.

Vitor Petrino (14-2) has surged to three straight wins since moving up to heavyweight, most recently grinding out a unanimous decision over Steven Asplund in March 2026. That followed a highlight-reel first-round KO of Thomas Petersen in October 2025 and a rear-naked choke submission of Austen Lane in his heavyweight debut. The surging Brazilian now looks to keep his momentum rolling as he comes into this fight this weekend against Serghei Spivac.

Why Serghei Spivac Will Win

Serghei Spivac brings a dangerous ground game into this heavyweight clash, having earned eight of his 18 career wins by submission, including a highlight finish over Marcin Tybura. That kind of proven finishing instinct on the mat gives him a real path to trouble Vitor Petrino if he can get the fight to the floor.

Petrino, while riding a three-fight winning streak, needed the judges’ scorecards in a tight decision over Steven Asplund in his most recent outing, suggesting his cardio and finishing power may not translate as cleanly at heavyweight. That kind of close call against a lower-ranked opponent raises questions about how he handles adversity against a more decorated veteran like Spivac.

Spivac also carries significant experience against the division’s best, having shared the cage with names like Ciryl Gane and Derrick Lewis, giving him a level of championship-caliber composure that Petrino has yet to be tested against. That experience gap could prove decisive if the fight extends into deeper rounds.

Given Spivac’s superior submission credentials and his track record against elite heavyweight competition, look for the “Polar Bear” to find his openings, drag the fight to the mat, and secure a finish over the streaking Brazilian in Sacramento.

Why Vitor Petrino Will Win

Vitor Petrino enters this fight riding a three-fight winning streak since making the jump to heavyweight, a run that includes a violent first-round knockout of Thomas Petersen. That kind of finishing power and rising confidence at the new weight class should serve him well against a veteran like Serghei Spivac.

Spivac, meanwhile, has struggled with consistency in recent years, going just 3-3 across his last six fights with a brutal first-round TKO loss to Jailton Almeida standing out as a major red flag on the feet. That kind of susceptibility to hard striking plays directly into Petrino’s biggest strength as a heavy-handed puncher.

At 28 years old, Petrino is also younger and further from the wear and tear of a long career compared to Spivac, who has been fighting professionally since 2014. That physical freshness could prove decisive if this fight extends past the first two rounds and durability becomes a factor.

Given Petrino’s finishing power, his current momentum, and the concerns about Spivac’s chin, look for the Brazilian to keep the fight standing, land the harder shots, and secure another impressive knockout win in Sacramento.

Final Serghei Spivac-Vitor Petrino Prediction & Pick

Expect Vitor Petrino to look to keep this fight standing early, using his crisp boxing and heavy hands to test Serghei Spivac’s chin from the opening bell. Given Spivac’s susceptibility to hard striking, most notably in his first-round TKO loss to Jailton Almeida, Petrino should look to press that same button rather than engage in prolonged grappling exchanges.

Spivac will likely search for takedowns to neutralize Petrino’s striking advantage, and his underrated ground game could produce a few dangerous scrambles. Still, Petrino’s added size and freshness at heavyweight should allow him to stuff a majority of those attempts and keep the fight in his preferred range.

As the fight progresses, look for Petrino’s volume and power to wear Spivac down, culminating in either a finish or a clear decision win. His current three-fight winning streak, combined with Spivac’s recent inconsistency, points toward Petrino extending his momentum with an emphatic performance in Sacramento.
