Vitor Petrino Sweeps Serghei Spivac, Extends Heavyweight Win Streak
Vitor Petrino won a unanimous decision over Serghei Spivac in the UFC Sacramento co-main event, taking every round on all three cards. The judges scored it 30-27, 30-27, and 30-27 after 15 minutes at Golden 1 Center.
The official result at UFC Fight Night: Hernandez vs. Rodrigues was a clean sweep. Sherdog’s round scoring matched the cageside cards, 10-9 Petrino in each round.
Petrino improved to 15-2 overall and 4-0 since moving to heavyweight. Spivac, nicknamed “The Polar Bear,” fell to 18-7.
The win also stretches Petrino’s UFC winning streak to four. That run now ranks second among active heavyweight streaks in the promotion, behind Valter Walker’s five-fight stretch.
All four of those Petrino wins have come at 265 pounds. He submitted Austen Lane in July 2025, knocked out Thomas Petersen in October, outpointed Steven Asplund in March, and now swept a ranked veteran in Spivac.
Spivac entered as a top-10 heavyweight and a slight underdog. He was coming off a unanimous decision over Ante Delija and still carried the résumé of wins over Marcin Tybura and Derrick Lewis.
Petrino, 28, listed 246 pounds to Spivac’s 257 at Friday’s weigh-in. The Brazilian used that speed and output to keep the Moldovan wrestler from turning the co-main into a clinch grind.
A 30-27 sweep against a ranked heavyweight is the kind of result that changes a ranking more than a highlight knockout. Petrino had already shown a finish in two of his first three heavyweight fights. Saturday he showed he can win ugly over three rounds against a veteran.
He said before the fight that Spivac was a bigger assignment than he expected. He also said a win should put him in five-round main events.
“I’m heading into my 11th UFC fight, so I believe the next step is to headline a card, have a five-round fight and really test myself, and show that we’re getting closer and closer to the goal, which is the belt,” Petrino told MMA Fighting.
That quote now sits on a 4-0 heavyweight record. Tom Aspinall holds the UFC heavyweight title, and Petrino is still climbing rather than knocking on the door of a title fight.
Walker remains the other name in the streak conversation. The Brazilian heel-hook specialist has the longest active UFC heavyweight winning streak at five, and Petrino has already said he would take that fight if it brought him more exposure.
“If it’s a fight that’s going to give me exposure, absolutely,” Petrino said. “I’ve asked for him before.”
The Vitor Petrino unanimous decision does not invent a title shot. It does move a former light heavyweight who used to cut nearly 30 kilos into the group of heavyweights matchmakers can sell as a co-main or a main event.
Petrino has been open that 205 pounds was ending his career. He is 4-0 since he stopped making that cut, with a knockout, a submission, and now two decisions.
No next opponent has been announced. Petrino leaves Sacramento 15-2, with the second-longest active UFC heavyweight win streak and a 30-27 win over a ranked veteran to take into the next booking.
