[2] After struggling financially for most of the 2023 season, the team was bought by the Charros de Jalisco, who replaced the Mariachis in the Mexican League.

[3][4] The team was established on 8 December 2020, when Mexican president Andrés Manuel López Obrador announced that two new teams would join the Mexican League for the 2021 season: a revival of El Águila de Veracruz (the original franchise was sold in 2017 and moved to Nuevo Laredo) and the Mariachis de Guadalajara.

[7] In March 2021, former Texas Rangers and Anaheim Angels shortstop Benji Gil was announced as the Mariachis' manager for the 2021 season.

The team owners, Carlos Valenzuela and Rafael Tejada, had debts with the players, personnel and an animation squad from Dominican Republic.

The club's owners even failed to pay the Jalisco's State Council for Sports Promotion for the use of the Estadio Panamericano.
