During Dean’s Major League Baseball (MLB) career, he played for the St. Louis Cardinals, Chicago Cubs, and St. Louis Browns. A brash and colorful personality, he is the last National League (NL) pitcher to win 30 games in one season (1934). After his playing career, “Ol’ Diz” became a popular television sports commentator. Dean was elected to the Baseball Hall of Fame in 1953. When the Cardinals reopened the team Hall of Fame in 2014, Dean was inducted among the inaugural class.
