Joseph Jefferson Jackson (July 16, 1887 – December 5, 1951), nicknamed "Shoeless Joe", was an American outfielder who played Major League Baseball (MLB) in the early 1900s.
He is remembered for his performance on the field and for his alleged association with the Black Sox Scandal, in which members of the 1919 Chicago White Sox participated in a conspiracy to fix the World Series.
As a result of Jackson's association with the scandal, Kenesaw Mountain Landis, Major League Baseball's first commissioner, banned Jackson from playing after the 1920 season despite exceptional play in the 1919 World Series, leading both teams in several statistical categories and setting a World Series record with 12 base hits.
Since then, Jackson's guilt has been fiercely debated with new accounts claiming his innocence, urging Major League Baseball to reconsider his banishment.
As a result of the scandal, Jackson's career was abruptly halted in his prime, ensuring him a place in baseball lore.
Jackson played for three Major League teams during his 12-year career.
He spent 1908–1909 as a member of the Philadelphia Athletics and 1910 with the minor league New Orleans Pelicans before joining the Cleveland Naps at the end of the 1910 season.
He remained in Cleveland through the first part of 1915; he played the remainder of the 1915 season through 1920 with the Chicago White Sox.
Later in life, Jackson played ball under assumed names throughout the south.
Jackson, who played left field for most of his career, currently has the third-highest career batting average in major league history.
In 1911, Jackson hit for a .408 average.
It is still the sixth-highest single-season total since 1901, which marked the beginning of the modern era for the sport.
His average that year also set the record for batting average in a single season by a rookie.
Babe Ruth said that he modeled his hitting technique after Jackson's.Jackson still holds the Indians and White Sox franchise records for both triples in a season and career batting average.
In 1999, he ranked number 35 on The Sporting News' list of the 100 Greatest Baseball Players and was nominated as a finalist for the Major League Baseball All-Century Team.
The fans voted him as the 12th-best outfielder of all-time.
He also ranks 33rd on the all-time list for non-pitchers according to the win shares formula developed by Bill James.
