Pavlovich enters this fight as a wounded lion coming off consecutive losses to Tom Aspinall and Alexander Volkov. The Russian power puncher built his reputation on devastating first-round knockouts, using his signature blitzing combination of jab-overhand right-left hook to overwhelm opponents like Curtis Blaydes, Tai Tuivasa, and Derrick Lewis. His 84-inch reach and explosive forward pressure made him nearly unstoppable during his knockout streak.
However, recent performances reveal a fighter dealing with confidence issues. Against Volkov, Pavlovich looked "bumbling" when unable to close distance against the southpaw stance and lead leg sidekicks. His typically aggressive blitzing was neutralized by Volkov's superior reach management and defensive positioning. Against Rozenstruik, Pavlovich abandoned his signature forward pressure entirely, opting for a wrestling-heavy approach that suggested a fighter afraid to engage in the firefights that once brought him success.
When Pavlovich commits to his combinations, he chains together devastating power shots with remarkable speed for a heavyweight. His defensive shell-to-counter approach allows him to absorb shots on his forearms before immediately returning fire with interest.
Pavlovich's confidence dependency has become his most glaring weakness. Following back-to-back losses, his output and commitment to forward pressure decreased dramatically against Rozenstruik, where he appeared tentative and "shook." This psychological fragility was exposed when Aspinall's relentless pressure overwhelmed him in just 69 seconds.
His linear forward movement makes him predictable against mobile opponents. Volkov exploited this by switching stances and using lateral movement, leaving Pavlovich swinging at air. When his primary blitzing attack fails, Pavlovich lacks secondary entries and often becomes frustrated, as seen in Round 2 against Volkov when he couldn't establish his preferred range.
Pavlovich's defensive gaps appear when opponents maintain distance through kicks and movement. His limited range management was evident against Volkov's lead leg sidekicks, which disrupted his forward momentum and prevented him from landing his power shots.
Cortes-Acosta brings an undefeated UFC record (6-1) and impressive recent form, winning five of his last six fights. The Dominican heavyweight operates as a methodical boxer-puncher who excels at controlled pressure and calculated power shots. His signature sequence involves body jabs followed by upstairs combinations, effectively manipulating opponents' defensive reactions.
Against Serghei Spivac, Cortes-Acosta showed excellent fight IQ by weathering early pressure before taking control through superior conditioning and tactical adjustments. His wrestling has evolved significantly, using well-timed double-legs after opponents commit to power shots. Against Ryan Spann, he demonstrated improved cardio management while maintaining technical effectiveness into later rounds.
Cortes-Acosta's boxing fundamentals are technically superior to most heavyweights. His jab-cross-left hook combinations are delivered with consistent accuracy, and his defensive head movement through weaving and slipping creates counter-striking opportunities. His body work, particularly the liver shot left hooks against Spann, shows his ability to systematically break down opponents.
Cortes-Acosta's kick defense remains problematic, as exposed by Marcos Rogerio de Lima's leg kick strategy that visibly hampered his mobility throughout their fight. He tends to back straight up rather than checking or countering kicks, allowing opponents to establish a kicking rhythm without consequence.
His tendency to drop his rear hand when stepping in with his jab creates openings for counter right hands, particularly dangerous against a power puncher like Pavlovich. This defensive lapse becomes more pronounced in later rounds as fatigue sets in.
Cortes-Acosta occasionally overcommits to power shots, leaving himself momentarily out of position during recovery phases. Against aggressive opponents who pressure immediately after his combinations, these brief windows could prove costly.
This matchup presents a fascinating contrast between Pavlovich's explosive but compromised aggression and Cortes-Acosta's methodical pressure boxing. Cortes-Acosta's patient approach could exploit Pavlovich's current hesitancy to engage in firefights. If Pavlovich attempts his traditional blitzing, Cortes-Acosta's superior boxing fundamentals and defensive head movement give him excellent counter-striking opportunities.
Cortes-Acosta's body jab strategy could be particularly effective against Pavlovich, who tends to carry his hands high in his defensive shell. By drawing Pavlovich's guard down with body shots, Cortes-Acosta can create openings for his overhand rights and left hooks upstairs—the same combination that troubled Spann.
However, if Pavlovich rediscovers his confidence and commits to his forward pressure, his reach advantage and power could overwhelm Cortes-Acosta's kick defense vulnerabilities. Pavlovich's ability to cut off the cage when motivated could force the exchanges where his knockout power becomes decisive.
Early rounds favor Cortes-Acosta's patient approach against the currently tentative Pavlovich. If Pavlovich starts cautiously as he did against Rozenstruik, Cortes-Acosta can establish his jab and begin implementing his body work strategy without facing the explosive blitzing that made Pavlovich so dangerous.
Mid-fight adjustments could see Pavlovich attempting to wrestle, as he did against Rozenstruik, but Cortes-Acosta's improved takedown defense and ability to return to his feet quickly should neutralize this approach. Cortes-Acosta's superior conditioning gives him an advantage in championship rounds, where his technical execution remains sharp while opponents fade.
• Confidence Factor: Pavlovich's psychological state following consecutive losses creates uncertainty about which version appears
• Technical Boxing: Cortes-Acosta's superior boxing fundamentals and defensive head movement favor him in extended exchanges
• Power vs. Patience: Pavlovich's knockout ability remains dangerous, but his reluctance to commit fully has diminished this threat
• Cardio Advantage: Cortes-Acosta's improved conditioning allows him to maintain technical effectiveness longer than most heavyweights
• Kick Defense: Cortes-Acosta's vulnerability to kicks could be exploited if Pavlovich incorporates leg kicks into his attack
The model's confidence stems primarily from Odds increasing the prediction score by 14.0, reflecting Pavlovich's betting favorite status despite recent struggles. Reach increased the score by 3.0, acknowledging Pavlovich's 6-inch reach advantage. However, Recent Win Percentage decreased the score by 3.0, reflecting Pavlovich's poor recent form (1-2 in last three). Recent Significant Striking Impact Differential also decreased by 3.0, indicating Cortes-Acosta's superior recent striking effectiveness.
WolfTicketsAI has a mixed record with Pavlovich, correctly predicting his wins against Rozenstruik, Tuivasa, Lewis, and Abdurakhimov, but missing on his losses to Volkov and Aspinall. The model showed particular confidence in Pavlovich against Aspinall (0.75 score) but was wrong, suggesting potential overvaluation of his knockout power. For Cortes-Acosta, the model has been largely accurate, correctly predicting five of his seven UFC fights, including his recent wins over Spivac and Spann.
Despite Pavlovich's power advantage and betting favorite status, his recent psychological struggles and technical limitations against patient, defensively sound opponents favor Cortes-Acosta's methodical approach. The Dominican's superior boxing fundamentals, improved conditioning, and ability to exploit Pavlovich's current hesitancy make him the more reliable pick. WolfTicketsAI's prediction of Pavlovich reflects the model's respect for his knockout power, but the technical evidence suggests Cortes-Acosta's patient pressure boxing will prevail over a diminished version of the Russian knockout artist.
