At tonight’s UFC Mexico City event, Lone’er Kavanagh delivered a stunning upset by defeating former flyweight champion Brandon Moreno via unanimous decision. The fight, held at the CDMX Arena, saw Kavanagh dominate early rounds and maintain his lead throughout, handing Moreno his second consecutive loss and shaking up the flyweight division rankings.
Background on Competitors Entering UFC Mexico City
Brandon Moreno came into the bout with a professional record of 23 wins, 10 losses, and 2 draws, aiming to recover from a recent TKO defeat to Tatsuro Taira at UFC 323 in Las Vegas last December. Before that setback, Moreno had earned back-to-back decision victories over top contenders Amir Albazi and Steve Erceg, reinforcing his status as one of the division’s elite fighters.
Meanwhile, Kavanagh, who holds a 10-1 professional record, was returning to competition after a loss to Charles Johnson in Shanghai last August, which marked his first career defeat. Prior to that, the Englishman had built an impressive 9-fight winning streak, including two UFC wins by decision, showcasing his rapid ascent within the flyweight ranks.
Kavanagh’s Commanding Performance Throughout the Fight
From the opening bell, Kavanagh asserted control, outstriking Moreno and controlling the pace during the initial rounds. Observers noted the young fighter’s effective use of low kicks and sharp striking to wear down the former champion early. While rounds three through five were more competitive, ‘The Assassin Baby’ was unable to generate sustained momentum or counter Kavanagh’s pressure.

Judges scored the fight 49-46 and 48-47 twice in favor of the English prospect, confirming his unanimous decision victory in the main event.
Round-by-Round Analysis and Expert Commentary
Experts and observers closely followed the fight’s dynamics, sharing insights as the action unfolded. Aaron Bronsteter highlighted Kavanagh’s
“STRONG first round from the prospect”
and observed,
“20-18 Kavanagh through two. He is picking the former champ apart and now it comes down to managing energy systems and heart as they approach the championship rounds.”
Henry Cejudo also weighed in, stating,
“10-9 Kavanagh. Very close round but the Englishman landed the more powerful shots. Great matchup #UFCMexico.”
Caposa, another commentator, noted,
“Sharp opening round from Kavanagh. Moreno starting to find more of his shots in the final 2 minutes or so. The low kicks from Lone’er are a problem,”
later adding,
“Well holy fuck. Early upset of the year could be in progress.”
The fight’s middle rounds saw Moreno gaining a slight edge in round three, with Bronsteter stating,
“10-9 Moreno in R3. 29-28 Kavanagh entering the championship rounds. Close round, but felt Moreno was the more effective striker.”
Nevertheless, Kavanagh’s consistent work in open space and superior striking in rounds four and five helped him maintain the lead, as Bronsteter remarked,
“10-9 Kavanagh in a razor close fourth round. Could go either way, but felt the limited work Kavanagh did in open space was far superior to what Moreno did in the clinch. 39-37 Kavanagh.”
In the final moments, Josh Thomson urged caution, stating,
“2-2 or 3-1 Kavanagh. Kavanagh needs to win this round and take nothing for granted,”
while Bronsteter anticipated,
“I have it 49-46 Kavanagh. Rounds 4 and 5 are the swing rounds.”
Immediate Reactions to the Unexpected Outcome
Following the bout, several fighters and media personalities expressed surprise at Kavanagh’s dominant showing. Terrance McKinney remarked,
“All jokes aside Kavanagh striking is nasty never seen Moreno get pieced up on the feet like this sheesh Moreno is tough my skinny calf’s ain’t taking that lol.”
Caposa reflected on the matchup’s unpredictability, admitting,
“I was flat out wrong about that fight. Baffling matchup on paper, off a KO loss. Short notice, at elevation in Mexico City against a former Mexican champ. I thought the moment would be too big. Kavanagh had ice in his veins. Upset and performance of the year contender.”
