Explanation: This is a prediction for a heavyweight fight in the UFC between two different fighting styles – a typical wrestler versus a stand-up fighter. Karl Williamson has a 3-0 record in the contender series, showing effective wrestling skills despite lacking knockout power in his hands. Facing Diniz, who has high finishing potential, Karl may struggle initially but could try to draw out the fight. Diniz’s striking may pose a threat, but Karl needs to maintain top form for 15 minutes to avoid being finished. Expect the fight to potentially go beyond 2.5 rounds, as the judges tend to favor impactful strikes over control. The suggested outcome is Diniz winning by decision.
