Drops controversial decision
FlyweightUFC
April 19, 2026
Horth lost to JJ Aldrich via unanimous decision (28-29, 28-29, 28-29) at UFC Fight Night 273 on Saturday in Winnipeg.
ANALYSIS
Rounds two and three were certainly close enough to be awarded to Aldrich. It is interesting to note, however, that Dr. Greg Jackson scored the first round for Aldrich, a round in which Horth outstruck her 23 to 9. While Aldrich landed her share of hard shots, Horth did control the majority of the fight, ultimately landing 70 significant strikes to Aldrich's 50. It's a blow for Horth, who was looking to build momentum coming off two consecutive wins. She fell to 9-3-0 in professional MMA due to the loss

Looking to climb into rankings
FlyweightUFC
March 15, 2026
Horth will take on JJ Alrich in a flyweight matchup at UFC Winnipeg on April 18.
ANALYSIS
Horth has won three of her last four fights, most recently finishing Tereza Bleda with a Round 1 TKO in December. While Aldrich sports a higher striking volume, Horth has been better defensively, in addition to advantages in takedown volume and takedown defense. Given Aldrich is currently ranked No. 15 at flyweight, Horth could grab a spot in the rankings for herself with a victory.
First stoppage win with UFC
FlyweightUFC
December 13, 2025
Horth defeated Tereza Bleda via TKO (punches) at 2:05 of Round 1 at UFC Fight Night on Saturday in Las Vegas.
ANALYSIS
Typically known as a decision machine, each of Horth's first five UFC bouts prior to this one saw the final bell. Here, against a very strong opponent in Bleda, Horth was able to fend off a deep takedown attempt and batter her opponent when the two finally separated. Referee Kerry Hatley gave Bleda plenty of time to recover, but Horth kept her foot on the gas and earned the stoppage. It was her first knockout since February 2020 and just the fourth of the 35-year-old's professional career.

Horth is scheduled to compete against Tereza Bleda in a flyweight fight at UFC Vegas 112 on Dec. 13, per Marcel Dorff of Eurosport.nl.

Takes decision in Atlanta opener
FlyweightUFC
June 14, 2025
Horth defeated Vanessa Demopoulous via unanimous decision (30-27, 30-27, 30-27) at UFC Fight Night on Saturday in Atlanta.
ANALYSIS
Horth agreed to this opponent change a little over a week ago following the withdrawal of Tereza Bleda (undisclosed) and ended up having no issues. She simply used her massive size advantage to pick Demopoulous apart at distance. Horth closed with a 115-44 edge in total strikes landed, in addition to connecting on a pair of takedowns. Horth is inexperienced with just 10 professional fights under her belt at age 35, but she's big and strong for the division and has proven an ability to consistently handle fringe-roster opposition. Horth has alternated wins and losses in her first five UFC bouts.
Late opponent change
FlyweightUFC
June 4, 2025
Horth will now take on Vanessa Demopoulos at UFC Atlanta on June 14 following the withdrawal of Tereza Bleda (undisclosed), Marcel Dorff of Eurosport.nl reports.
ANALYSIS
The bout is presumed to be contested at flyweight, as originally planned, so Horth should have a bit of a size advantage against Demopoulos, a natural stawweight taking this bout on short notice. In fact, she'll have five inches in height and seven inches in reach over her opponent, on paper. Demopoulos has also lost back-to-back fights, while Horth is looking to bounce back from a loss of her own to Miranda Maverick in December.
