Charles Arnold "Chick" Gandil was an American professional baseball player. He played for the Washington Senators, Cleveland Indians, and Chicago White Sox of the American League. He is best known as the ringleader of the players involved in the 1919 Black Sox scandal. Described by his contemporaries as a "professional malcontent", he was physically well-built at 6 ft 2 in (1.88 m) and 195 lb (88 kg), and had a stern and challenging demeanor. He used both to display his toughness, and also did not hesitate to use sheer strength to get his point across.

Major League Baseball (MLB) is a professional baseball league and the highest level of organized baseball in the United States and Canada. One of the big four major leagues, MLB comprises 30 teams, divided equally between the National League (NL) and the American League (AL), with 29 in the United States and 1 in Canada. Formed in 1876 and 1901, respectively, the NL and AL cemented their cooperation with the National Agreement in 1903, making MLB the oldest major professional sports league in the world. They remained legally separate entities until 2000, when they merged into a single organization led by the Commissioner of Baseball. MLB is headquartered in Midtown Manhattan.
