The series between the Tigers and Chicago White Sox is one of the oldest active rivalries in the league today. Both teams joined the American League in 1901 after being charter members of the original Western League. Both have actively played one another annually for over 120 seasons. As is often the case between professional sports teams located in Chicago or Detroit, there usually exists a rivalry as such with the Bulls–Pistons rivalry of the NBA, the Blackhawks–Red Wings rivalry of the NHL, and the Bears–Lions rivalry of the NFL. Despite playing one another for over 2,200 games, both teams have yet to meet in the postseason.
