The 2018 season was a year of rebirth for Atlético San Luis, a team that had experienced ups and downs in previous decades. After being relegated to the Liga de Ascenso in 2015, the Tuneros faced a challenging and arduous path. However, with a combination of young talent and experience, the club finally achieved its goal of returning to Liga MX.

Under the guidance of coach Alfonso Sosa, the team displayed a dynamic and attractive style of play that captivated fans. The roster included players like Mauro Quiroga, who became the team's top scorer, and his ability to find the net in crucial moments was vital for the season's success. The Potosí fanbase felt a renewed connection to the club, filling the stands of Estadio Alfonso Lastras and creating an unwavering support atmosphere.

One of the most memorable moments of that season was the second leg of the Ascenso MX final against Atlético San Luis, held on May 19, 2018. The Tuneros secured a 3-2 aggregate victory, ensuring the championship and, more importantly, promotion to the top division. The excitement in the stands was palpable as fans overflowed with joy seeing their team reclaim its rightful place in Mexican football.

The victory represented not only a rise but also symbolized the perseverance and collective effort of players, coaching staff, and fans. From that moment on, Atlético San Luis began to forge a new identity in Liga MX, facing traditional rivals like Club León with renewed confidence.

The 2018 season served as a reminder that football is a sport full of surprises and that, with determination and teamwork, it is possible to overcome the most challenging obstacles. This milestone not only revitalized the club but also established a solid foundation for the future, where the dreams of Potosí fans began to take shape once again in the top tier of Mexican football.
