The "Cimarrones de Sonora" were born in 2013, when the "Rays" of Poblado Miguel Alemán FC became the champions of the Third Division of Mexico and thus were promoted to Second División 2.

After the ascent, with the goal of reaching the Liga de Ascenso of Mexico, employers and trustees of Hermosillo origin, led by Edmundo Ruiz, acquired the franchise as a whole, since this had an agreement with the Necaxa.

After this happens, the Mexican Football Federation will communicate to employers that the franchise did not have approval to participate in the precinct Miguel Aleman, since it lacked the minimum infrastructure requirements, hospitality, transportation, etc.

That's when managers decided to move the franchise to Hermosillo, renaming the club to "Maroons of Sonora" and having as coach Enrique Ferreira.

In the summer of 2020, financial problems of the member clubs of Ascenso MX caused the second level of Mexican football to become the Liga de Expansión MX, a new league focused on the development of footballers, so in exchange for financial support, promotion was eliminated for six years, Cimarrones was one of the founding teams of the new league.

In June 2024 this squad became the club's main team to ensure the historical continuity of the Cimarrones, although playing in a lower category than they did between 2015 and 2024.
