It's tickets sold, they do that in virtually all sports now. And as with all MLB teams, 80-90% of attendance is decided the year before. The Twins will continue to consistently draw crowds of >30,000 the whole year except maybe in September. Despite what announcers and ESPN say, it has nothing to do with the "loyalty" of the fan base, they already bought their tickets and it's too late. Hence the low resale values. It's already easy to predict that next year the Twins will have the #1 drop in attendance. The Marlins will probably be #2 and if the Brewers keep at a < 80 win pace, they will lose several thousand fans per game in 2013 as well. The Angels are also looking like a candidate for attendance problems in 2013. This stuff is easy to predict and I'm sure every front office knows it.
