Billy Quarantillo built his reputation on relentless pressure and high-volume striking, but he's looked noticeably slower and less effective in recent outings. Diego Ferreira is older, yet he still has meaningful power and a size advantage with Quarantillo moving up from featherweight.

Given the recent form of both fighters, Ferreira should be able to control the exchanges and punish Quarantillo’s increasingly predictable pressure.

Diego Ferreira vs Billy Quarantillo best bet: Ferreira to win by KO/TKO (+240)

Best bet
Ferreira to win by KO/TKO (+240)
Bet now at BET99

Ferreira by KO/TKO/DQ is my best bet. Quarantillo getting stopped by Cub Swanson two years ago raised legitimate concerns about his durability, and now he'll be returning from a lengthy layoff while moving up in weight.

Ferreira’s power and Brazilian jiu-jitsu credentials give Quarantillo few safe avenues to dictate the fight. Quarantillo will resort to trading, giving Ferreira an easy route to a stoppage. 

Covers COVERS INTEL: Diego Ferreira has five knockouts in 12 UFC finishes, while Quarantillo has been stopped in three of his last five losses.

While Ferreira is four years older, he remains the more physical fighter and enters in better form. Quarantillo's pressure-heavy style should create entertaining exchanges, but a long layoff and his declining form make this a tough match for him.
