Comiskey's reputation was permanently tarnished by his team's involvement in the Black Sox Scandal, a conspiracy to "throw" the 1919 World Series which some have excused by allegations that his poor treatment of White Sox players fueled the conspiracy. Comiskey was inducted as an executive into the Baseball Hall of Fame in 1939.
After five seasons of sharing the Twin Cities with another Western League club in Minneapolis, Comiskey and his colleagues arranged to share Chicago with the National League, whose club (the Chicago Cubs today) played on the West Side. The St. Paul Saints moved to the South Side as the White Stockings of the renamed American League for the 1900 season. The American League then declared itself a major league starting in 1901.
Charles Comiskey, circa 1910
As owner of the White Sox from 1900 until his death in 1931, Comiskey oversaw building Comiskey Park in 1910 and winning five American League pennants (1900, 1901, 1906, 1917, 1919) and two World Series (1906, 1917). He lost popularity with his players, whose views of him became hateful, and that is seen as a factor in the Black Sox scandal, when eight players on the AL champions conspired to "throw" the 1919 World Series to the NL champion Cincinnati Reds. Comiskey was notoriously stingy (his defenders called him "frugal"), even forcing his players to pay to launder their own uniforms. Traci Peterson notes that, in an era when professional athletes lacked free agency, the White Sox's formidable players had little choice but to accept Comiskey's substandard wages. She writes: "Charles Risberg and Claude Williams made less than $3,000 a year. Joe Jackson and George Weaver made only $6,000 a year. Eddie Cicotte had been promised a $10,000 bonus if he could win 30 games in a season. When Cicotte closed in on the 30-game goal, Comiskey had him benched to keep him from reaching the mark". In one incident, he promised his players a bonus for winning the 1919 pennant — the "bonus" turned out to be a case of flat champagne.
When the scandal broke late in the 1920 season, Comiskey suspended the suspected players, while admitting in the telegram he sent to them that he knew this action cost the White Sox a second straight pennant. However, he initially defended the accused players and, in an unusual display of largesse, provided them with expensive legal representation. He ultimately supported baseball commissioner Kenesaw Mountain Landis' decision to ban the implicated White Sox players from further participation in professional baseball, knowing full well that Landis' action would permanently sideline the core of his team. Indeed, the White Sox promptly tumbled into seventh place and would not be a factor in a pennant race again until 1936, five years after Comiskey's death.
Comiskey is sometimes credited with the innovation of playing the first base position behind first base or inside the foul line, a practice which has since become common. Later he had played a large role in the dissolution of the National Commission, baseball's former body of authority, following a quarrel with Ban Johnson. He was inducted into the National Baseball Hall of Fame in 1939.
Comiskey died in Eagle River, Wisconsin in 1931. Comiskey's son J. Louis inherited the team but died a few years later. The trustees of his estate were going to sell the team, but J. Louis' widow Grace was able to gain control of the team and avoid a sale. Her two children, Dorothy Comiskey Rigney and Charles Albert Comiskey II (who served in the White Sox front office in the 1940s and 1950s before he became owner), became co-owners of the team following Grace's death in the 1950s.
