Espino did pretty well during the summer, too. He debuted with Monterrey in 1962 and hit .371 while crashing 46 homers two years later. He was signed by St. Louis and spent a short time with the Cards’ AAA affiliate in Jacksonville that year (batting an even .300 in 32 games), but never played outside Mexico again. In his 24-year Mexican League career, Espino hit .335 with 453 homers and 1,573 RBIs.
He was elected to the Salon de la Fama in 1988 and is considered by many the greatest domestic player in Mexican baseball history. Espino died of a heart attack at age 58 in 1997.
