9 innings
Mexican professional baseball games follow the same standard as Major League Baseball, with 9 innings making up a complete game. If the score is tied after 9 innings, extra innings are played until one team leads at the end of a full inning. This structure applies to both the Mexican League (Liga Mexicana de Béisbol) and the Mexican Pacific League (Liga Mexicana del Pacífico).
