She currently fights in the women’s Flyweight division of the Ultimate Fighting Championship, where she is the former UFC Women’s Flyweight Champion. Grasso is the first Mexican woman to win a UFC championship, a milestone that placed her alongside Brandon Moreno as one of the most important Mexican champions in company history. In addition to her fighting career, she also works as a UFC analyst for UFC Español on Spanish-language broadcasts, helping bring the sport to new audiences across Latin America.
Early Life and Background
Early Life and Background
Karen Alexa Grasso Montes was born on August 9, 1993, in Guadalajara, Jalisco, Mexico, and she continues to live and train in her hometown. She is Mexican by nationality, and her connection to Guadalajara has shaped both her personal life and her fighting identity. From an early age, Grasso showed interest in combat sports, a path that was nurtured within her family before she moved into formal martial arts training.
Grasso developed her early skills under the guidance of her father, Francisco “Pancho” Grasso, who has served as one of her trainers throughout her career. She has spoken about the influence of her family on her development as an athlete, including her close working relationship with her father and her Brazilian Jiu-Jitsu coach Diego Lopes. Her upbringing in Guadalajara placed her near the Lobo Gym MMA team, the camp where she has built much of her professional foundation.
Alexa Grasso Career
Early Career (2012–2014)
Alexa Grasso made her professional mixed martial arts debut in December 2012 in her native Mexico. During the first eighteen months of her career, she built an undefeated record of five wins and no losses, finishing three opponents by technical knockout and earning two additional victories by decision. That early run established her as one of the most promising strawweight prospects in Mexico and gave her the experience needed to test herself on an international stage.
After taking a year away from active competition, Grasso signed with Invicta Fighting Championships, a leading all-women MMA promotion. She made her Invicta FC debut on September 6, 2014, against Ashley Cummins at Invicta FC 8, winning the fight by unanimous decision. A second Invicta appearance followed on December 5, 2014, at Invicta FC 10, when she defeated Alida Gray by technical knockout in the first round.
Invicta FC Breakthrough (2014–2015)
Grasso’s third Invicta FC appearance came on February 27, 2015, in the co-main event of Invicta FC 11, where she faced Mizuki Inoue. She won the fight by unanimous decision, and the bout also earned her first Fight of the Night bonus award, signaling her growing reputation as an entertaining and dangerous competitor. A planned title challenge against Livia Renata Souza for the Invicta Strawweight Championship at Invicta FC 14 was scheduled for September 12, 2015, but Grasso was forced to withdraw due to injury.
UFC Breakthrough (2016–2022)
On August 11, 2016, it was announced that Alexa Grasso had signed with the Ultimate Fighting Championship. She made her promotional debut on November 5, 2016, against Heather Jo Clark at The Ultimate Fighter Latin America 3 Finale: dos Anjos vs. Ferguson in Mexico City, Mexico, winning by unanimous decision. Her first UFC loss came on February 4, 2017, at UFC Fight Night 104, when she dropped a unanimous decision to Felice Herrig, ending her long unbeaten run.
Over the next several years, Grasso faced a series of ranked opponents across the strawweight division. She bounced back with a split decision win over Randa Markos at UFC Fight Night: Pettis vs. Moreno on August 5, 2017, after dealing with a urinary tract infection that forced her to compete at a catchweight. Losses to Tatiana Suarez and Carla Esparza tested her, but she also picked up a Fight of the Night award for her bout with Esparza at UFC on ESPN+ 17 on September 21, 2019. A missed weight cut ahead of a scheduled fight with Cláudia Gadelha at UFC 246 in January 2020 led Grasso to announce her move to the flyweight division, a change that reshaped her career.
The move paid off quickly. Grasso won her flyweight debut against Ji Yeon Kim on August 29, 2020, and followed it with a decision win over Maycee Barber at UFC 258 on February 13, 2021. After injury cancellations and visa issues that disrupted several bookings, she submitted Joanne Wood with a rear-naked choke in the first round at UFC on ESPN 33 on March 26, 2022, and earned a unanimous decision victory over Viviane Araújo at UFC Fight Night 212 on October 15, 2022. Those results positioned her as a serious contender in a new weight class.
UFC Championship Era (2023–Present)
On March 4, 2023, at UFC 285, Alexa Grasso faced Valentina Shevchenko for the UFC Women’s Flyweight Championship and produced one of the biggest upsets in division history. Despite entering as a heavy underdog, Grasso won the bout via a face crank in the fourth round to capture the title, becoming the first Mexican UFC women’s champion. The performance also earned her first Performance of the Night bonus award.
Grasso’s first title defense came in a rematch against Shevchenko on September 16, 2023, at UFC Fight Night 227, a fight that ended in a split draw and left the championship picture unresolved. The pair were then announced as opposing coaches on The Ultimate Fighter 32 on ESPN+, which featured middleweight and featherweight contestants. Their trilogy bout took place on September 14, 2024, at UFC 306, where Shevchenko reclaimed the title by unanimous decision after controlling long stretches of grappling. In her first non-title bout since 2022, Grasso dropped a unanimous decision to Natália Silva at UFC 315 on May 10, 2025, before returning to the win column with a first-round knockout of Maycee Barber in a rematch at UFC Fight Night 271 on March 28, 2026, a finish that earned a $100,000 Performance of the Night award and drew praise from UFC president Dana White.
Style and Strengths
Grasso is known for her well-rounded skill set, combining sharp boxing with a steadily improving grappling base developed under her Brazilian Jiu-Jitsu coach Diego Lopes. Her transition to flyweight sharpened her speed and cardio, and she has shown the ability to threaten opponents both on the feet and on the ground, including a memorable face-crank finish of Valentina Shevchenko. Training out of Lobo Gym MMA in Guadalajara alongside her father Francisco “Pancho” Grasso has given her a stable foundation for high-level competition.
Notable Events and Milestones
Grasso’s signature moment remains her fourth-round submission of Valentina Shevchenko at UFC 285 to become the first Mexican UFC women’s champion. Her recent first-round knockout of Maycee Barber at UFC Fight Night 271 was later described by Dana White as one of the greatest knockouts in the history of the sport, and it earned her a six-figure Performance of the Night bonus. She has also collected multiple Fight of the Night bonuses during her UFC tenure, including awards for her bouts with Mizuki Inoue and Carla Esparza.

2025 Season Performance
The 2025 campaign was a transitional year for Alexa Grasso following her loss of the UFC Women’s Flyweight Championship to Valentina Shevchenko at UFC 306 in September 2024. Returning to non-title competition for the first time since 2022, she faced Natália Silva at UFC 315 on May 10, 2025, in Montreal, Quebec, Canada, and dropped a unanimous decision in a fight that did little to clarify her path back to a title shot.
A planned bout with former two-time UFC Women’s Strawweight Champion Rose Namajunas at UFC 324 on January 24, 2026, was postponed when Grasso withdrew due to injury on December 3, 2025, with Silva stepping in as her replacement. The setback, however, opened the door for a quick reset, and Grasso was matched again with Maycee Barber, an opponent she had already defeated, this time in a rematch.
On March 28, 2026, at UFC Fight Night 271, Grasso produced one of the most talked-about finishes of her career, a first-round knockout of Barber that earned her a $100,000 Performance of the Night award. The win ended a two-fight skid and drew public praise from UFC president Dana White, who called the knockout one of the greatest in the sport’s history. Entering the next phase of her career, Grasso remains ranked in the UFC women’s flyweight division and is widely viewed as a leading contender in a deep and competitive weight class.
