Jamey-Lyn Horth vs Vanessa Demopoulos fight analysis

Introduction

The women’s flyweight showdown between Jamey-Lyn Horth and Vanessa Demopoulos is set to ignite the preliminary card of UFC Fight Night: Usman vs Buckley on Saturday, June 14, 2025, at the State Farm Arena in Atlanta, Georgia. As the prelims officially kick off at 11:00 PM ET, fight fans can expect this contest to hit the Octagon shortly thereafter, offering an early glimpse at two rising contenders vying to make a statement on a stacked UFC card.

Standing across the cage at the same 125-pound limit, these two athletes bring contrasting skill sets and motivations to the fight game’s global stage. On one side, Jamey-Lyn Horth of Vancouver, Canada, enters as a significant -400 favorite (BestOnline.ag) thanks to her well-rounded striking pedigree, highlighted by a 52% significant strike accuracy and a stout 61% defense rate. A 34-year-old kickboxer who debuted in the UFC in April 2023, Horth holds a 7-2 professional record, including three knockouts and two submissions. Her performance to date has shown a calm, technical approach, relying on precise combinations and excellent takedown defense (72%) to neutralize grapplers and dictate the pace.

Opposite her stands Vanessa Demopoulos, the 36-year-old Brazilian Jiu-Jitsu specialist from Cleveland, Ohio, who comes in as a +330 underdog. Despite her underdog tag, Demopoulos boasts an 11-7 professional ledger with four submission victories and a knack for early finishes—four fights ended inside the distance in the opening stanza. Her credentials include a 41% striking accuracy and a willingness to mix it up on the feet before hunting for submissions. While her takedown accuracy sits at just 12%, her ability to threaten with chokes and armbars has made her a dangerous opponent for anyone who leaves an opening.

Both fighters carry momentum in different forms. Horth bounced back from a unanimous decision loss to Miranda Maverick in December by edging Ivana Petrovic via split decision at UFC 294. Meanwhile, Demopoulos is looking to snap a two-fight skid that saw her submit Jaqueline Amorim and fall by decision to Talita Alencar earlier in 2025. With Horth’s crisp striking and rock-solid defense against Demopoulos’s submission instincts and scrappy style, this bout promises an intriguing battle for positional control.

From a betting perspective, Horth’s heavy favorite status reflects the oddsmakers’ confidence in her versatility and athleticism. Demopoulos, meanwhile, offers attractive value to bettors willing to back the underdog in a compelling stylistic clash. As the prelims heat up in Atlanta, all eyes will be on this pivotal women’s flyweight tilt that could shape the division’s landscape moving forward.
