Rogers Hornsby was a player and then player-manager from 1915 through 1926, and in 1933. Hornsby is represented by an SL emblem because he didn’t have a true number in his time with the Cardinals. In 1923 and 1924 when the Cardinals experimented with sleeve numbers, Hornsby wore number 4 on one uniform and number 6 on another uniform. When he returned in 1933, he wore number 4. Hornsby wore many different uniforms and logos in his time with the Cardinals.
