Chicago White Sox

The Chicago White Sox are an American professional baseball team based in Chicago. The White Sox compete in Major League Baseball (MLB) as a member club of the American League (AL) Central Division. The club plays its home games at Rate Field, which is located on Chicago's South Side. They are one of two MLB teams based in Chicago, alongside the National League (NL)'s Chicago Cubs. The White Sox are known as the "South Siders", a reference to the location of their home park.

The White Sox originated in the Western League, founded as the Sioux City Cornhuskers in 1894, moving to Saint Paul, Minnesota, as the St. Paul Saints, and ultimately relocating to Chicago in 1900. The Chicago White Stockings were one of the American League's eight charter franchises when the AL asserted major league status in 1901. The team, which shortened its name to the White Sox in 1904, originally played their home games at South Side Park before moving to Comiskey Park in 1910, where they played until 1990. They then moved into a new home, which was also known as Comiskey Park like its predecessor and later carried sponsorship from U.S. Cellular, for the 1991 season.

The White Sox won their first World Series, the 1906 World Series against the Cubs, with a defense-oriented team dubbed "the Hitless Wonders", and later won the 1917 World Series against the New York Giants. Their next appearance, the 1919 World Series, was marred by the Black Sox Scandal in which eight members of the White Sox were found to have conspired with gamblers to fix games and lose the World Series to the Cincinnati Reds. In response, the new Commissioner of Baseball, Kenesaw Mountain Landis, banned the players from the league for life. The White Sox have only made two World Series appearances since the scandal. The first came in 1959, where they lost to the Los Angeles Dodgers, before they finally won their third championship in 2005 against the Houston Astros. The 88 seasons it took the White Sox to win the World Series stands as the longest MLB championship drought in the American League, and the second longest in both leagues, to the Cubs' 108 seasons.

From 1901 to 2025, the White Sox have an overall win-loss record of 9,659–9,730–103 (.498).

The White Sox originated as the Sioux City Cornhuskers of the Western League, a minor league under the parameters of the National Agreement with the National League. In 1894, Charles Comiskey bought the Cornhuskers and moved them to St. Paul, Minnesota, where they became the St. Paul Saints. In 1900, with the approval of Western League president Ban Johnson, Charles Comiskey moved the Saints into his hometown neighborhood of Armour Square, where they became the Chicago White Stockings, the former name of Chicago's National League team, the Orphans (now the Chicago Cubs).

In 1901, the Western League broke the National Agreement and became the new major league American League. The first season in the AL ended with a White Stockings championship. However, that would be the end of the season, as the World Series did not begin until 1903. The franchise, now known as the Chicago White Sox, made its first World Series appearance in 1906, beating the crosstown Cubs in six games.

The White Sox won a third pennant and a second World Series in 1917, beating the New York Giants in six games with help from stars Eddie Cicotte and "Shoeless" Joe Jackson. The Sox were heavily favored in the 1919 World Series, but lost to the Cincinnati Reds in eight games. Huge bets on the Reds fueled speculation that the series had been fixed. A criminal investigation went on in the 1920 season, and although all players were acquitted, commissioner Kenesaw Mountain Landis banned eight of them for life, in what was known as the Black Sox Scandal. This set the franchise back, as they did not win another pennant for 40 years.

The White Sox did not finish in the upper half of the American League again until after founder Charles Comiskey died and passed ownership of the club to his son, J. Louis Comiskey. They finished in the upper half most years between 1936 and 1946, under the leadership of manager Jimmy Dykes, with star shortstop Luke Appling (known as "Ol' Aches and Pains") and pitcher Ted Lyons, who both had their numbers 4 and 16 retired.
