Dorados de Sinaloa won the Apertura title with a 4-2 aggregate victory over Atlante, while Lobos BUAP took the Clausura title with a 4-2 aggregate victory of their own against FC Juárez.
Dorados were quite recently in the first division, as they won promotion in 2015, but they were quickly relegated after just one year in Liga MX. They will look to bounce right back into the top division and this time, stay there, with a victory in the promotion playoff.
As for Lobos, they have never been in Liga MX in their 49-year-history, starting in the third division in the 60s, and then joining the second division when the club relaunched in the mid-90s, before moving to Primera A, later renamed Ascenso MX, in 2004.
