Carlos Diego Ferreira vs. Billy Quarantillo Prediction
Ferreira enters at 19-7 and has lost two straight, first dropping a unanimous decision to Grant Dawson before Alexander Hernandez stopped him in the second round last September. Before that skid, Ferreira produced consecutive knockout victories over Michael Johnson and Mateusz Rebecki. Even approaching 42, he remains dangerous everywhere because of his Brazilian jiu-jitsu and ability to transition quickly once opponents expose their backs or hips.
Quarantillo is 18-7 and has also lost consecutive fights, most recently suffering a third-round knockout against Cub Swanson in December 2024. The layoff is significant, but moving to lightweight removes the difficult featherweight cut and could improve his durability and energy management. Quarantillo has consistently built his success around pace, output and forcing opponents to work through uncomfortable exchanges rather than relying on one-shot finishing power.
Ferreira’s grappling creates a pathway for significant control time without necessarily producing a submission. Quarantillo has historically been difficult to keep out of fights, and his willingness to scramble can extend exchanges even when he gives up position. Ferreira should prioritize control rather than engaging in unnecessary brawls, particularly after being stopped in his previous appearance.
The move to 155 pounds also gives Quarantillo reason to fight more patiently. He no longer needs to drain himself to reach featherweight and can use the additional size and energy to withstand Ferreira’s physical grappling. Both men understand the consequences of another loss, which should encourage a more tactical fight than the under 2.5 price suggests.
Carlos Diego Ferreira vs. Billy Quarantillo Pick
- Pick: Fight to Go the Distance (+165) Check out these best odds at DraftKings Sportsbook
The market heavily favors a finish with under 2.5 rounds at -154, making the opposite outcome attractive. Ferreira may still be the more likely winner because of his positional grappling, but Quarantillo’s toughness and volume should keep him competitive enough to survive. At +165, backing the fight to reach the judges offers the stronger value.
