In 2008 and 2009, Esparza was a women's wrestling All-American with the Menlo Oaks.[2]
While in college, Esparza started training in Brazilian jiu-jitsu at the Gracie Academy in Torrance under Rener, Ryron, and Ralek Gracie. She then expanded her mixed martial arts repertoire when she began training at Team Oyama during the summer of her junior year of college.[9]
Mixed martial arts career
Bellator
In August 2010, only six months after her pro debut and with just three professional MMA fights, Esparza was called in by Bellator MMA as a last-minute replacement for Angela Magaña, who was forced to withdraw from her upcoming fight due to a foot injury.[10] Esparza was inserted in the bracket of the Bellator Season 3 115 lb women's tournament at Bellator 24. On just three days' notice, Esparza's opponent in the quarterfinal round was the undefeated and then #1 pound-for-pound female MMA fighter in the world, Megumi Fujii.[10] Esparza lost the fight to the heavily favored Fujii via second-round armbar submission.[11][12]
In June 2011, Esparza returned to the Bellator cage and faced fellow Season 3 tournament challenger Jessica Aguilar at Bellator 46.[13][14] After a three-round back and forth battle, Aguilar defeated Esparza via split decision.[15][16]
XFC and MEZ Sports
On December 2, 2011, Esparza made her XFC debut against Felice Herrig at XFC 15: Tribute in Tampa, Florida.[17] She defeated Herrig via unanimous decision.[18]
Three months later, Esparza was scheduled to face Angela Magana at Pandemonium VI for the MEZ Sports women's flyweight title.[19][20] Unfortunately, Magana was involved in a car accident on the day of the fight while in transit to the Riverside Convention Center, where the event was being staged.[21] Magana re-broke her back in the collision and was unable to compete in the fight.[22]
On July 28, 2012, Esparza made her Invicta debut at the promotion's second event, entitled Invicta FC 2: Baszler vs. McMann, and faced Sarah Schneider on the preliminary card.[23] Esparza won the fight via TKO (punches) at 4:28 of round two.[24]
Esparza returned to Invicta to face Lynn Alvarez at Invicta FC 3: Penne vs. Sugiyama on October 6, 2012.[25] She defeated Alvarez via TKO (punches) at 2:53 of round one.[26]
On December 7, 2013, Esparza was set to defend her strawweight title against Cláudia Gadelha at Invicta FC 7.[36] However, on the day of the event, Gadelha was taken to the hospital due to a bacterial infection and the fight was canceled. Esparza vacated the title on December 11, 2013 to compete on The Ultimate Fighter.[37]
The Ultimate Fighter
On December 11, 2013, it was announced that Esparza was signed by the Ultimate Fighting Championship (UFC) along with 10 other strawweight fighters to compete on season 20 of The Ultimate Fighter, which would crown the first ever UFC Strawweight Champion.[38]
Esparza was the top seed in the tournament. She faced Angela Hill in the preliminary round and won via submission in the first round. In the quarterfinal round, she faced Tecia Torres and won the fight via majority decision.[39] She then faced teammate Jessica Penne in the semifinal, and won by unanimous decision.[40]
Ultimate Fighting Championship
By winning the tournament on The Ultimate Fighter, Esparza advanced to the final on December 12, 2014, against Rose Namajunas.
Strawweight Champion
"She did an outstanding job. Standing on her feet and on the ground, she completely dominated. She took her down at will. I say it every season but the best rise to the top on the show, and she definitely did tonight."
—UFC President Dana White on Esparza's title victory[6]
After dominating much of the fight with her grappling and ground strikes, Esparza defeated Namajunas via rear-naked choke in the third round to become the inaugural UFC Strawweight Champion. The result also earned Esparza a Performance of the Night bonus.[41]
Kevin Iole of Yahoo Sports noted, "Namajunas tapped at 1:26 of the third round, but the fight was over long before that. Esparza was too strong, too smart and simply too good for the far less experienced Namajunas." He went on to state that "Esparza dominated her three fights on the reality show and was no less dominant on Saturday. There is clearly a gap between Esparza and the next level of challengers".[6] Following the fight, Brad Walker of MMATorch declared, "Esparza is the best fighter in her division in the world, not just in the UFC."[42]
In her first title defense, Esparza faced kickboxer Joanna Jędrzejczyk on March 14, 2015, at UFC 185. Prior to the fight, Jędrzejczyk stated, "I have lots of respect for her." She also noted, "I know she's not going to give up easy, so it's going to be a tough fight for me and for her."[43] Throughout the bout, Esparza was out-struck while standing and unable to keep Jędrzejczyk on the mat. Jędrzejczyk won via TKO in the second round. In an interview afterward, Esparza noted, "She had great takedown defense, obviously. I feel like I wasn't really setting it up, but that's on me."[44] She went on to state, "There's never any excuses. I fought my fight and I lost tonight. She did a great job."[44]
Esparza underwent shoulder surgery in mid-2015 and subsequently was out of action for the rest of the year.[45]
Rebound
Esparza returned at UFC 197 on April 23, 2016, defeating Juliana Lima via unanimous decision. Esparza, who stepped in for Jessica Aguilar, noted, "I took this fight semi-last minute, and I kind of wanted it that way too. Even though I wasn't in the best shape I wanted to be, I just kind of wanted to avoid the stress of a long camp." She also stated, "It's a huge relief off my shoulders to go out there and get my hand raised."[46]
Esparza was expected to face Amanda Ribas on December 12, 2020 at UFC 256.[71] However on October 9, it was announced that Esparza was pulled due to undisclosed reasons.[72]
Esparza faced Rose Namajunas in a rematch for the UFC Women's Strawweight Championship on May 7, 2022 at UFC 274.[76] Esparza won a largely uneventful fight by split decision to claim the UFC Women's Strawweight Championship for a second time. Alongside the UFC 248 main event, it was widely regarded as one of the most boring UFC title fights of all time.[77] With the victory, Esparza set a record for longest time between UFC title reigns by any fighter, male or female, at 2,612 days.[78]
In her first defense, Esparza faced Zhang Weili on November 12, 2022, at UFC 281.[79] She lost the bout and the belt by way of a rear-naked choke submission in the second round.[80]
Retirement bout
Esparza faced Tecia Pennington on October 5, 2024 at UFC 307.[81] She lost the fight by unanimous decision and retired after the bout.[82]
Grappling career
Esparza stepped up on short notice to replace Rose Namajunas in a grappling match against Danielle Kelly at Fury Pro Grappling 3 on December 30, 2021.[83] After a tough match, Esparza slammed Kelly from full guard and the resulting clash of heads opened up a cut above Esparza's eyebrow. The doctors attending called the match off and the victory was awarded to Kelly as a result of the injury.[84]
Fighting style
Esparza is known for powerful wrestling and Brazilian jiu-jitsu.[6][85] On the mat, she often mounts an opponent and controls her with strikes while seeking submissions.[86] While standing, she typically clinches and attacks with punches, knees and elbows.[87]
