Example Input: Question: How many professional boxers did Garcia train? Passage:Despite being forced to retire from pro boxing Díaz kept in shape by lifting weights at a local gym. The gym owner was impressed with Díaz physique and work ethics and recommended he become a luchador. Díaz was originally trained by Ray Carrasco and later also trained under Rogelio de la Paz, Genaro Contreas, Raul Rojas and Daniel García; the latter would later be famous under the name of "Huracán Ramírez". Díaz made his professional wrestling debut in 1954, using the ring name "El Pelón" (Spanish for "Baldy") Chato Díaz, then later on worked under names such as "Indio" Mendoza, El Rayo Rojo and El Hombre del Rayo Rojo. He also worked for a while as an enmascarado (masked) character called Gargantua between 1954 and 1955. In 1955 Díaz came up with the ring name "Ray Mendoza" after his mentor Ray Carrasco and his wife's maiden name Mendoza. As Mendoza he quickly forged a very effective Rudo character ("bad guy") by using well developed physique and charisma to create a ring character that the fans loved to hate. In 1956 Mendoza began working for Salvador Lutteroth's Empresa Mexicana de Lucha Libre (EMLL), the world's oldest and Mexico's largest wrestling promotion. He made his debut at EMLL's main arena Arena Coliseo in February, 1956 in a Battle Royal that also included EMLL headliners Gory Guerrero, El Santo, Cavernario Galindo, Blue Demon and Black Shadow, a match that immediately established him as someone who Lutteroth saw potential in. In EMLL Mendoza struck up a friendship with René Guajardo and Karloff Lagarde out of the ring and a "partnership in crime" in the ring as the three became one of the most hated trio in lucha libre at the time. The three drew full houses all over Mexico, setting box office record after box office record as they faced técnicos(good guys) such as El Santo, Rayo de Jalisco or Blue Demon. They also had a very financially successful feud with Los Espantos (Espanto I, Espanto II, and Espanto III) in what at the time was a rare rudo vs. rudo feud. Outside the ring Mendoza, Guajardo and Lagarde often spoke out on behalf of the wrestlers, demanding higher pay and better conditions, and since they were able to generate a lot of ticket sales EMLL officials listened to their demands.
