Detroit Tigers, Detroit Tigers

There are numerous Tigers fans in Ontario, as evidenced by Detroit's proximity to Windsor and the fact that the Tigers once had a minor league team in London. Sarnia, Ontario also has a large Detroit Tigers fanbase. Some are rivalries for first place during the regular season, with all American League teams until 1969, with American League East teams from 1969 to 1997, and with American League Central teams from 1998 until the present. Finally, some are rivalries with National League teams the Tigers have faced repeatedly in the World Series, the Chicago Cubs (four times) and St. Louis Cardinals (three times). Had the Cubs beat the Padres in the 1984 NLCS, they would have faced the Tigers for a fifth time in the World Series.
