Alexi Cassila made up for his base running blunder by tagging late causing him to get thrown out at home with a huge base hit to the right side scoring the winning run in the 12th.
I also believe that the Twins victory depended on the quality play of these individuals:
Scott Baker for overcoming a 3-0 deficit and settling down and giving the Twins three more solid scoreless innings.
Orlando Cabrera for his uncharacteristic 2-run home run in the 7th inning, and heads up double play with the Tigers threatening in the 9th.
Nick Punto for his amazing patience at the plate, and his ability to get on the bases.
Bobby Keppel for keeping his cool in the 12th with the bags juiced. Keppel was able to prevent the Tigers from crossing the plate and scoring a decisive run in this close contest.
Carlos Gomez for getting a 12th inning single, when almost all Twins fans must have been counting him out.
The Twins winning 17 of their last 21 games to overcome a 7 game September lead to those hated Tigers is nothing short of remarkable, and all this done without Justin Morneau.
This is Ron Gardenhire's 5th AL Central Division Title in 8 years.
