Alexa Grasso: Early Life and Combat‑Sports Roots
Raised in a combat‑sports household where her great‑grandfather boxed professionally and her uncle, Francisco Grasso, taught Muay Thai, Alexa was immersed in martial arts culture from childhood. At fifteen she joined the family‑run Lobo Gym, drilling footwork, jab precision, and clinch knees alongside cousin Irene Aldana, laying the foundation for the aggressive pocket‑boxing that would later define her UFC style.
The teenage prospect quickly amassed a 3‑0 amateur record on the Mexican regional circuit, finishing two opponents by first‑round knockout and sparking early buzz among North American scouts. Those victories—captured on grainy regional broadcasts—still circulate on YouTube highlight channels, illustrating a raw talent destined for bigger arenas.
Invicta FC Rise: Perfect Run to 8‑0
Show‑Stealing Debut
Invicta FC signed Grasso in 2014, and her promotional debut at Invicta 8 against Ashley Cummins was an instant classic. Throwing over 200 strikes, she earned unanimous 30‑27 scorecards and a “Fight of the Night” bonus that vaulted her into fan consciousness.
Highlight‑Reel Finishes
The momentum continued with a blistering first‑round TKO of Alida Gray and a split‑decision thriller versus Mizuki Inoue. By out‑landing the durable Japanese kickboxer in a high‑tempo stand‑up duel, Grasso showcased cardio and composure beyond her years. Her 8‑0 Invicta résumé, capped by a main‑event win over Jodie Esquibel, convinced UFC matchmakers that Mexico had produced a new star.
UFC Strawweight Trials (2016–2019)
Promising Debut, Painful Lessons
Grasso entered the Octagon on November 5, 2016, out‑striking veteran Heather Jo Clark 86‑63 to secure a confident decision. Yet subsequent defeats to Felice Herrig and wrestling ace Tatiana Suárez exposed holes in her clinch framing and scrambling, dropping her takedown‑defense rate to the mid‑50s.
Technical Overhaul
Rather than plateau, Grasso doubled down on wrestling drills at Lobo Gym, hosting visits from NCAA athletes to sharpen sprawls and cage escapes. The payoff surfaced at UFC on ESPN 1 in February 2019 when she out‑boxed former title challenger Karolina Kowalkiewicz, landing 78 significant strikes while stuffing late takedown attempts. That victory reignited her career and prompted a pivotal decision to leave strawweight behind.
Move to Flyweight: Unleashing Full Potential
Severe weight cuts had sapped her speed; moving to 125 lbs in January 2020 revitalized every aspect of her game. Grasso’s flyweight debut at UFC 246 ended via second‑round rear‑naked choke over Joanne Wood, earning a performance bonus and revealing newfound grappling confidence.
She then rattled off wins against Ji Yeon Kim, Maycee Barber, Viviane Araújo, and Taila Santos, posting over 50 % striking accuracy and 70 % takedown defense across the stretch. Analysts noted crisper combinations, improved defensive footwork, and a willingness to hunt submissions—metrics that made her a legitimate title threat.
Historic UFC 285 Triumph over Valentina Shevchenko
On March 4, 2023, at UFC 285, Grasso authored one of MMA’s great upsets. Switching from orthodox to southpaw, she baited Shevchenko’s spinning back kick, pounced to secure back control, and forced the champion to tap to a face‑crank at 4:34 of Round 4. The win cemented her as Mexico’s first female UFC champion and only the second Mexican‑born titleholder overall.
Noche UFC Rematch Drama
The highly anticipated rematch on September 16, 2024—Mexico’s Independence Day weekend—ended in a split draw after five grueling rounds. Grasso out‑landed Shevchenko 262–199 in total strikes but conceded four takedowns, leading to heated debate over a controversial 10‑8 score in the final frame. The stalemate preserved her belt and set chatter ablaze for a potential trilogy.

Weekly sessions with visiting U.S. wrestlers and BJJ black belts keep the curriculum fresh and challenging.

Legacy for Mexican Women in MMA
By breaking the championship barrier, Grasso ignited a 40 % increase in female membership at Mexican MMA gyms within six months of UFC 285. Her success, coupled with Brandon Moreno’s flyweight reign, has prompted the UFC to schedule regular Mexico‑themed events, underscoring the nation’s growing influence on the global fight scene.
