Just in case your spine isn't still tingling from last night, and just in case the "wow" factor of the Twins' improbable comeback to win the division isn't enough, take a look at that image from coolstandings.com.
According to that site's calcuations, the Twins had a 4 percent chance of winning the division and making the playoffs when they were 3 games out with 4 to play. The numbers, of course, kept improving from there until yesterday, when Minnesota finally overtook Detroit at the last possible moment.
Also let it be known the Twins are also given a 40 percent chance of winning the ALDS according to the site, though the prediction is Yankees in 4).
Spend some time over there. It's a pretty cool site, indeed.
