Malcolm Wellmaker

The Machine

USA

Second straight poor performance
BantamweightUFC
May 17, 2026
Wellmaker lost to Juan Diaz via submission (Rear-Naked Choke) at 4:08 of Round 2 at UFC Fight Night on Saturday in Las Vegas.
ANALYSIS
That's back-to-back horrendous performances from Wellmaker as a significant favorite. He was even worse here against Diaz than against Ethyn Ewing last November. Malcolm has legitimate power and looks quite good hitting pads in the back, but he doesn't seem to process things all that well inside the Octagon. He basically completely wilted under the pressure of Diaz, allowing five takedowns on eight attempts. Where he goes from here is an open question. Wellmaker will be 32 years old in early-June, so he's not as young as your typical "prospect."

Booked against debuting opponent
BantamweightUFC
May 11, 2026
Wellmaker will take on Juan Diaz in a bantamweight matchup at UFC Vegas 117 on Saturday.
ANALYSIS
Wellmaker suffered his first pro loss against Ethyn Ewing last November but now looks to bounce back against a debuting opponent in Diaz. Diaz is a fellow Contender Series product who picked up his contract last April. Wellmaker's UFC experience, as well as two-inch advantages in both height and reach, likely explain why he's as high as a (-280) betting favorite as of the start of fight week.
Loses to late-notice opponent
BantamweightUFC
November 15, 2025
Wellmaker lost to Ethyn Ewing via unanimous decision (27-30, 28-29, 28-29) at UFC 322 on Saturday in New York City.
ANALYSIS
Wellmaker agreed to face Ewing exactly 48 hours ago following the withdrawal of Cody Haddon (foot), and he ended up paying for it. In the end, it wasn't much of a surprise. Malcolm has ridiculous power, but we've never seen much else from him. He struggled with the constant pressure of Ewing, and his cardio looked lousy, the latter of which isn't surprising since none of his prior three fights lasted longer than 2:37. To make matters worse, at 31 years old, Wellmaker isn't a kid. He needs a rebound performance his next time out.
