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 when the Cardinals first experimented with sleeve numbers, Hornsby wore number 4 on one uniform and number 6 on another uniform, and in 1924 he wore number 6. When he returned in 1933, he wore number 4. Hornsby wore many different uniforms and logos in his time with the Cardinals.
