Back in 2025, the Central American Baseball Association had a huge six-team expansion. This brought the Caribbean League to 20 teams and the Mexican League to 18. The plan was always to also bring the ML to 20 teams, but officials felt adding eight teams at once was too many. By 2030, the plan was in motion to add two more teams to get the Mexican League to 20 teams.



The Aguascalientes Cactus and Tuxtla Terror were the two teams added into the Mexican League. The ML had kept a two-division format to that point, while the Caribbean League had switched to three divisions following the 2025 expansion. The ML made the same switch now with 20 teams for a format with two divisions of seven teams and one with six.

The North Division would have Tijuana, Juarez, Mexicali, Chihuahua, Hermosillo, Monterrey, and Torreon. The South Division had Mexico City, Ecatepec, Merida, Puebla, Cancun, Toluca, and Tuxtla. The new Central Division would have Leon, Guadalajara, Queretaro, Culiacan, San Luis Potosi, and Aguascalientes.



CABA also for 2030 lowered the service time requirements for free agency from six years to only five, a big win for the players. This put CABA even with East Asia Baseball, the Oceania Baseball Association, and South Asia Baseball as the least restrictive of the world leagues.
