Juan Diaz

Overview

Juan Diaz's only UFC win came by submission, in the second round, after a Contender Series knockout that landed with two seconds left in the same round. "Pegajoso" is a Peruvian bantamweight who trains at the UFC Performance Institute Mexico City. His professional record across all promotions is 16-1-1, and his UFC record is 1-0.

One fight in, he's undefeated in the UFC, and both of his most recent wins were finishes.

UFC Career

Diaz fought on Dana White's Contender Series 9.10 in October 2025, a professional fight but not a UFC event. He stopped Kwon WonIl by KO/TKO in round 2 at 4:58.

His UFC debut came at UFC Fight Night: Allen vs Costa in May 2026. He submitted Malcolm Wellmaker in round 2 at 4:08, and he carries a one-fight win streak into his next bout.

It's a small sample, but he has finished both of his most recent fights in the second round.

Fighting Style

Diaz is a hard fighter to hit. He lands strikes at about the UFC average but takes fewer than most, and his striking defense is a strength.

The ground game is where he stands out. He shoots for takedowns constantly and hunts for submissions more than most. His one UFC win came by submission in the second round.

The weak spot is takedown defense. He gets taken down more than most, so opponents can put him on the mat as easily as he tries to do the same to them.
