About Mariana Juárez
Born 1980. Mariana Juárez is a Mexican boxer.
María Anastasia Juárez Trejo (born 29 January 1980), better known as Mariana Juárez, is a Mexican professional boxer. She is a former two-division world champion, having held the WBC female flyweight title from March 2011 to October 2012 and the WBC female bantamweight title from April 2017 to October 2020.She is the older sister of boxer Lourdes Juárez, also a former world champion.
Professional career Juárez made her professional debut on 22 May 1998, scoring a second-round knockout victory over Virginia Esparza in Mexico City, Mexico.
Already the interim title holder for almost two years, Juárez became full WBC female flyweight World champion when she defeated the previously unbeaten Italian Simona Galassi on 11 March 2011, at Jose Cuervo Salon, Polanco, Mexico.
She successfully defended her title seven times
She would hold the belt for more than two years, making nine successful defences before dropping the title via unanimous decision to compatriot Yulihan Luna at the Grand Oasis Arena, Cancun, Mexico on 31 October 2020. The contest was marred by controversy as Juarez, who suffered a broken nose in the opening round, interrupted Luna's post-fight interview to accuse the new champion of using doctored gloves. Officials examined the gloves and ruled them fully legal with Juarez later apologising for her outburst.
Back on home soil at Domo Corona del Hipodromo de las Americas, Mexico City, Mexico, Juárez captured the WBC female super-bantamweight Silver title on 26 April 2024, beating South Africa's Matshidiso Mokebisi by technical knockout in round nine.
