Profile

Overview

Four UFC finishes, and none of them came in round one. Billy Quarantillo, a Buffalo lightweight, is a fighter whose wins arrive late: two in round two, two in round three, zero in the first.

His UFC record is 6-6, and his professional record across all promotions is 18-8-0. He debuted on December 6, 2019, and his longest UFC win streak is three. He carries a three-fight losing streak into his next bout.

Six wins, six losses. A fighter who tends to be in the fight, win or lose.

UFC Career

Quarantillo's path ran through Dana White's Contender Series 3.5, where he beat Kamuela Kirk by KO/TKO in round three. That fight sits outside the UFC record. His UFC debut followed that December, a second-round submission of Jacob Kilburn at 3:18.

He then added a unanimous decision over Spike Carlyle and a seven-second TKO of Kyle Nelson in round three, giving him his three-fight win streak. It ended with a unanimous decision loss to Gavin Tucker at UFC 256.

Mid-career was a split. He stopped Gabriel Benitez in round three, then dropped a decision to Shane Burgos. A round-two TKO of Alexander Hernandez at UFC 282 was followed by a first-round TKO loss to Edson Barboza, his quickest defeat. A decision win over Damon Jackson came next.

Then the losses stacked up. Youssef Zalal submitted him in round two, Cub Swanson stopped him in round three, and Diego Ferreira took a unanimous decision.

Three straight losses, by submission, TKO and decision.

Fighting Style

Quarantillo is a busy striker who throws a lot and lands at a good clip. He is accurate with what he throws, and he is also a constant submission threat, going after finishes far more often than most UFC fighters.

That pace comes with a price. He gets hit more than most, and his striking defense is below the UFC average. He is hard to take down, but he doesn't lean on wrestling to win rounds.

His finishing pattern fits the profile. Of his four UFC wins by stoppage, three are TKOs and one is a submission, and all of them came after the opening round. He has no first-round finishes in the UFC.

His losses are split as well: two by KO/TKO, one by submission, and three by decision.

He pushes the pace, takes some punishment along the way, and tends to close the show late.
