The first rendition of the Athletics' uniforms included a blue script A on the left chest and featured a collar, similar to that of a dress shirt. Shown modeling the 1903 uniform is right-handed pitcher Chief Bender. In 1910, Bender had a 1.93 ERA in the World Series as the A's defeated the Chicago Cubs to win their first World Series. In 1911, he tied Christy Mathewson's record of three complete games in a World Series. Many have credited Bender with creating the slider, known then as a "nickel curve." Jimmy Dykes - 1920
