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 Saint 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, before demolishing and rebuilding Comiskey Park in 1990, which is now known as Rate Field.
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 , where they lost to the Los Angeles Dodgers, before they finally won their third championship in 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 ().
History
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.
After J. Louis Comiskey died in 1939, ownership of the club was passed down to his widow, Grace Comiskey. The club was later passed down to Grace's children Dorothy and Chuck in 1956, with Dorothy selling a majority share to a group led by Bill Veeck after the 1958 season. Veeck was notorious for his promotional stunts, attracting fans to Comiskey Park with the new "exploding scoreboard" and outfield shower. In 1961, Arthur Allyn, Jr. briefly owned the club before selling to his brother John Allyn.
From 1951 to 1967, the White Sox had their longest period of sustained success, scoring a winning record for 17 straight seasons. Known as the "Go-Go White Sox" for their tendency to focus on speed and getting on base versus power hitting, they featured stars such as Minnie Miñoso, Nellie Fox, Luis Aparicio, Billy Pierce, and Sherm Lollar. From 1957 to 1965, the Sox were managed by Al López. The Sox finished in the upper half of the American League in eight of his nine seasons, including six years in the top two of the league. In 1959, the White Sox ended the New York Yankees' dominance over the American League, and won their first pennant since the ill-fated 1919 campaign. Despite winning game one of the 1959 World Series 11–0, they fell to the Los Angeles Dodgers in six games.
During the late 1960s and 1970s, the White Sox struggled to win games and attract fans. The team played a total of 20 home games at Milwaukee County Stadium in the 1968 and 1969 seasons. Allyn and Bud Selig agreed to a handshake deal that would give Selig control of the club and move them to Milwaukee, but it was blocked by the American League. Selig instead bought the Seattle Pilots and moved them to Milwaukee, where they would become the Milwaukee Brewers, putting enormous pressure on the American League to place a team in Seattle. A plan was in place for the Sox to move to Seattle and for Charlie Finley to move his Oakland A's to Chicago. However, the city had a renewed interest in the Sox after the 1972 season, and the American League instead added the expansion Seattle Mariners. The 1972 White Sox had the lone successful season of this era, as Dick Allen wound up winning the American League MVP award. Bill Veeck returned as owner of the Sox in 1975, and despite not having much money, they managed to win 90 games in 1977, with a team known as the "South Side Hitmen".
However, the team's fortunes plummeted afterwards, plagued by 90-loss teams and scarred by the notorious 1979 Disco Demolition Night promotion. Veeck was forced to sell the team, rejecting offers from ownership groups intent on moving the club to Denver and eventually agreeing to sell it to Ed DeBartolo, the only prospective owner who promised to keep the White Sox in Chicago. However, DeBartolo was rejected by the owners, and the club was then sold to a group headed by Jerry Reinsdorf and Eddie Einhorn. The Reinsdorf era started off well, with the team winning their first division title in 1983, led by manager Tony La Russa and stars Carlton Fisk, Tom Paciorek, Ron Kittle, Harold Baines, and LaMarr Hoyt. During the 1986 season, La Russa was fired by announcer-turned-general manager Ken Harrelson. La Russa went on to manage in six World Series (winning three) with the Oakland A's and St. Louis Cardinals, ending up in the Hall of Fame as the second-winningest manager of all time.
The White Sox struggled for the rest of the 1980s, as Chicago fought to keep them in town. Reinsdorf wanted to replace the aging Comiskey Park, and sought public funds to do so. When talks stalled, a strong offer was made to move the team to St. Petersburg, Florida. Funding for a new ballpark was approved in an 11th-hour deal by the Illinois State Legislature on June 30, 1988, with the stipulation that it had to be built on the corner of 35th and Shields, across the street from the old ballpark, as opposed to the suburban ballpark the owners had designed. Architects offered to redesign the ballpark to a more "retro" feel that would fit in the city blocks around Comiskey Park; however, the ownership group was set on a 1991 open date, so they kept the old design. The new ballpark opened in 1991 under the name new Comiskey Park. The park, renamed in 2003 as U.S. Cellular Field and in 2016 as Guaranteed Rate Field, underwent many renovations in the early 2000s to give it a more retro feel. In December 2024, it was renamed Rate Field when Guaranteed Rate rebranded as Rate.
The White Sox were fairly successful in the 1990s and early 2000s, with 12 winning seasons from 1990 to 2005. First baseman Frank Thomas became the face of the franchise, ending his career as the White Sox's all-time leader in runs, doubles, home runs, total bases, and walks. Other major players included Robin Ventura, Ozzie Guillén, Jack McDowell, and Bobby Thigpen. The Sox won the West division in 1993, and were in first place in 1994, when the season was canceled due to the 1994 MLB strike.
In 2004, Ozzie Guillén was hired as manager of his former team. After finishing second in 2004, the Sox won 99 games and the Central Division title in 2005, behind the work of stars Paul Konerko, Mark Buehrle, A. J. Pierzynski, Joe Crede, and Orlando Hernández. They started the playoffs by sweeping the defending champion Boston Red Sox in the ALDS, and beat the Angels in five games to win their first pennant in 46 years, due to four complete games by the White Sox rotation. The White Sox went on to sweep the Houston Astros in the 2005 World Series, giving them their first World Championship in 88 years.
Guillén had marginal success during the rest of his tenure, with the Sox winning the Central Division title in 2008 after a one-game playoff with the Minnesota Twins. Guillén left the White Sox after the 2011 season and was replaced by former teammate Robin Ventura. The White Sox finished the 2015 season, their 115th in Chicago, with a 76–86 record, a three-game improvement over 2014. The White Sox recorded their 9,000th win in franchise history by the score of 3–2 against the Detroit Tigers on September 21, 2015. Ventura returned in 2016, with a young core featuring José Abreu, Adam Eaton, José Quintana, and Chris Sale. Ventura resigned after the 2016 season, in which the White Sox finished 78–84. Rick Renteria, the 2016 White Sox bench coach, was promoted to the role of manager.
Prior to the start of the 2017 season, the White Sox traded Sale to the Boston Red Sox and Eaton to the Washington Nationals for prospects including Yoán Moncada, Lucas Giolito and Michael Kopech, signaling the beginning of a rebuilding period. During the 2017 season, the White Sox continued their rebuild when they made a blockbuster trade with their crosstown rival, the Chicago Cubs, in a swap that featured the Sox sending pitcher José Quintana to the Cubs in exchange for four prospects headlined by outfielder Eloy Jiménez and pitcher Dylan Cease. This was the first trade between the White Sox and Cubs since the 2006 season.
