2009 was a historic season for the Twins. They closed out their 28-year stay in the Metrodome; Joe Mauer had one of the greatest seasons ever for a catcher; and the Twins completed an unprecedented comeback to win the AL Central. They climbed into a tie for first place on October 3rd for the first time since May 14th, and when they won the tiebreaker game it was the first time they'd been alone atop the division since they were 3-2 on April 10th. Although, perhaps there is some precedent, as the Twins also extended the Tigers' division title drought with a late-season comeback in 2006, which now sits at 22 years.
Also, an interesting note: the Twins' longest win streak of the season until mid-September was 4 games. After September 12th, they had 3 separate winning streaks of 5 or more games.

I'm not going to write anything about those guys here because that'll be covered when I break down each player's individual season.
