Joseph Edward Cronin (1906-1984) was an American professional baseball player, manager and executive. He played in Major League Baseball (MLB) as a shortstop, most notably as a member of the Boston Red Sox. Cronin spent over 48 years in baseball, culminating with 14 years as president of the American League (AL). During his 20-year playing career (1926-1945), Cronin played for the Pittsburgh Pirates, Washington Senators and the Boston Red Sox; he was a player-manager for 13 seasons (1933-1945), and served as manager for two additional seasons (1946-1947). A seven-time All-Star, Cronin became the first American League player to become an All-Star with two teams; he was elected to the Baseball Hall of Fame in 1956.
