Was the Twins Dome advantage just a fallacy?

March 12, 2010 – For years opposing players and managers and writers across the country have complained about the huge home advantage that the HHH Metrodome provided for the Minnesota Twins. But when you look at the actual numbers, you will see that the Twins actually had a better winning percentage when they played at Metropolitan Stadium than they had at the Metrodome. It is also interesting to me that the Twins appeared to be a better road team when they played at Met Stadium then when they played at the Metrodome. Maybe calling the Dome home was a disadvantage when they went on the road? Another fun fact is that the Twins best decade was the 60’s. It will be interesting to see what Target Field has in store for the Twins in 2010 and beyond.
