Overview
Mexico's summer league — twenty clubs, Triple-A classification, and altitude that makes it one of the highest-scoring leagues in the world.
The Liga Mexicana de Béisbol is Mexico's premier summer baseball league and the country's oldest professional sports competition. Twenty clubs are split into North and South zones and play from April to August, with a postseason ending in the Serie del Rey.
The league holds Triple-A classification within the international structure but operates independently of MLB's farm system. Several of its parks sit at high altitude — Mexico City is above 2,200 metres — which makes the LMB one of the highest-scoring environments in professional baseball.

History
Founded in 1925, the LMB drew several Negro Leagues stars in the 1930s and 1940s at a time when Major League Baseball was still segregated, and briefly raided MLB rosters in 1946 under owner Jorge Pasquel — a challenge that led to suspensions for the players who went.
The separate Liga Mexicana del Pacífico plays a winter season and supplies Mexico's entrant to the Caribbean Series. Mexico reached the semi-finals of the 2023 World Baseball Classic, beating Puerto Rico and the United States along the way.
Governance
The LMB is governed by its member clubs and sits under the Mexican Baseball Federation and the WBSC.
