Musial was born in Donora, Pennsylvania, where he frequently played baseball informally or in organized settings, and eventually played on the baseball team at Donora High School. Signed to a professional contract by the St. Louis Cardinals as a pitcher in 1938, Musial was converted into an outfielder and made his major league debut in 1941. Noted for his unique batting stance, he quickly established himself as a consistent and productive hitter. In his first full season, 1942, the Cardinals won the World Series. The following year, he led the NL in six different offensive categories and earned his first MVP award. He was also named to the NL All-Star squad for the first time; he appeared in every All-Star game in every subsequent season he played.
