Mexico has been home to professional baseball for the past 80 years, thanks to the presence of the Mexican League. Additionally, several other leagues have existed in Mexico, including the winter-season Mexican Pacific League and some low minor leagues. The first Mexican player to appear in the majors was Mel Almada, who made his major-league debut in 1933. After that a steady stream has come from Mexico, including MLB stars like Bobby Avila, Fernando Valenzuela, Vinny Castilla and Teddy Higuera.
