The Twins started competing on the Bloomington prairie in the spring of 1961. The Chicago White Sox are the only team with which the Twins have shared a grouping for the entirety of 51 seasons: American League (1961-68), AL West (1969-1993) and AL Central (1994-present).
The Twins and the White Sox had a bit of a rivalry early on. Chicago beat out the Twins by three games to finish second behind the Yankees in 1963. The White Sox were second by seven games to the pennant-winning Twins in 1965. The Twins and the White Sox were involved with Boston (the winner) and Detroit in the Great Race of 1967.
There wasn't much to offer from Twins vs. White Sox after that until the turn of the century. The teams were scoring runs in bundles and battling for the AL West lead in midsummer of 1977, before both ran out of pitching and faded.
The decade of 2001 to 2010 was different. The Twins won six Central titles, and lost a Game 163 to the White Sox in 2008. The White Sox won two division titles, the World Series in 2005 and finished second to the Twins three times.
The teams went to 2011 spring training with the highest payrolls in franchise histories: $128 million for the White Sox and $113 million for the Twins.
The White Sox offered the marketing slogan, "We're All In." The Twins settled for confident talk of an outstanding lineup 1 through 9, about two experienced closers to draw from in Joe Nathan and Matt Capps, and about a rotation that had six viable starters for five spots.
The White Sox fell to 79-83 and finished third, 16 games behind Detroit. The Twins were last at 63-99 and twice as many games behind the Tigers.
The White Sox and the Twins have gone in the same direction since then: downward in payroll and in veteran talent.
