Profile

Overview

Eighteen UFC fights, seventeen of them going the distance. JJ Aldrich is a women's flyweight whose UFC record stands at 11-7, and the only finish she has ever scored came in the second round against Liang Na.

That tells you what she is. Ten of her 11 UFC wins are decisions, and she has also gone to the scorecards in five of her seven losses. The other two losses came inside the distance. Her 15-8-0 professional record, which includes fights outside the UFC, adds some context, but the UFC line is the one that matters here. She enters her next fight on a one-fight losing streak.

She wins by points, not by finishes.

UFC Career

Aldrich debuted in December 2016 with a unanimous decision loss to Juliana Lima. She answered with three straight unanimous decision wins, over Chan-Mi Jeon, Danielle Taylor and Polyana Viana. That three-fight run is her longest win streak in the UFC.

It ended against Maycee Barber, who stopped her in the second round at 3:01 in March 2019. A win over Lauren Mueller followed, then a split decision loss to Sabina Mazo at UFC 246.

The middle of her run was her best stretch. She beat Cortney Casey by split decision, then took unanimous decisions over Vanessa Demopoulos and Gillian Robertson. Erin Blanchfield submitted her in the second round in June 2022, her only submission loss. Ariane da Silva then beat her on the cards.

In August 2023 she finally got a finish, stopping Liang Na in the second round at 4:49. She followed it with a decision win over Montana De La Rosa. Then came a loss to Veronica Hardy, a win over Andrea Lee, a win over Jamey-Lyn Horth, and a unanimous decision loss to Regina Tarin.

Her record against opponents our model rates as elite is 0-0 in terms of wins. She has no UFC wins over elite opposition.

Her UFC career comes down to one result: the judges.

Fighting Style

Aldrich is a southpaw striker who lands more than the typical UFC fighter and avoids strikes better than most. She absorbs and lands at a rate close to average in accuracy, so the edge comes from volume and defense, not from precision.

She is not a grappler. She rarely shoots for takedowns and rarely hunts submissions, but she is very hard to take down. That fits the pattern in her fights: she has one submission loss, to Blanchfield, and no submission wins.

Her finishing numbers are thin. One stoppage win in 18 UFC fights means her wins come from accumulating rounds, not from ending them early.
