Liga MXA Independiente In 2020, Obson Dynamo joined the third division of the
Liga MXA Independiente, a semiprofessional league, with Benjamín Valenzuela Dennis as their manager. José Miguel Fisher Castell was the team president. In their competitive debut in December, they defeated Iguanas FC de Los Mochis by a score of 19–0, with nine different players getting on the scoresheet. Obson Dynamo developed a rivalry with Cócorit FC, which was dubbed
El clásico de Cajeme, as both teams were based in the municipality of
Cajeme. Their first encounter resulted in a 3–2 Cócorit victory. In their first season, Obson Dynamo was one of eight clubs that qualified for the
Liguilla, the end-of-season tournament. However, Obson Dynamo was defeated 1–0 by their rivals, Cócorit, in the semifinals. Obson Dynamo was then invited to play in the Liga Élite, a newly created first-tier league organized by the Liga MXA Independiente. They were one of eight teams chosen based on their "structure and economic solvency", with two spots reserved for the champions in the top two tiers of the Liga MXA's existing league structure. Obson Dynamo signed the reigning Liga MXA
most valuable player, José Luis Rodríguez, in preparation for the competition. While still playing in the Liga Élite, Obson Dynamo began their regular season in the Liga de Ascenso MXA Independiente. In the Clausura 2021 season, Obson Dynamo won the Liga de Ascenso title, defeating Toros Retro 3–1 in the final at home.
Liga TDP (2022–present) In July 2021, Obson Dynamo announced its intention to make the jump to the professional ranks and join the third-tier
Liga TDP the following year. The last team from Ciudad Obregón to play in the league, Guerreros de Obregón, disappeared in 2017. In their league debut, they suffered a 1–0 defeat to
Cobras Fut Premier. Even then, they lost a
penalty shootout following regulation time, which was mandated due to league rules, earning one point while Chihuahua earned two. They finished the season ninth in their group with a record of five wins, five draws and 10 losses. ==Stadium==
