## Professional career

She faced Seniesa Estrada for the WBA interim female flyweight title on November 2, 2019 at the MGM Grand Garden Arena in Paradise, Nevada. The bout formed part of the undercard for Canelo Álvarez vs Sergey Kovalev. The bout was stopped at the end of the ninth round, on the advice of the ringside doctor, after Esparza suffered a cut in the fifth round from an accidental clash of heads, handing her the first defeat of her professional career by way of a unanimous technical decision.
Esparza won her first professional world title by defeating WBC flyweight champion Ibeth Zamora Silva via unanimous decision at Don Haskins Center, El Paso, Texas, on 19 June 2021.
She became a unified world champion when she scored a unanimous decision win over WBA title holder Naoko Fujioka at the Alamodome, San Antonio, Texas, on 9 April 2022, in a contest which was also for the inaugural Ring female world flyweight championship.
On July 8, 2023, at the AT&T Center in San Antonio, Texas, Esparza defeated Gabriela Celeste Alaniz by majority decision to add the WBO female flyweight title to her collection.
Esparza was scheduled to defend her WBA, WBC, WBO flyweight titles in a rematch against Alaniz on March 16, 2024, in Las Vegas but the fight was postponed due to challenger's US VISA issue. The fight eventually took place on April 27, 2024, at Save Mart Arena, Fresno, California, although Esparza missed weight by 2 lbs, and was ineligible to keep the titles in case of her victory. Alaniz won the contest by split decision.
