The main story here is that the Twins don't have any plans to move the fences after this season, and I'm glad to hear that. But I found the conclusion a little flawed and I think it's because Shooters examination is a little flawed....
The Minnesota Twins' Target Field has yielded an average of 2.09 home runs per game this season, ranking seventh in the 14-team American League, according to ESPN Stats and Information Group.
Just figuring the average home runs hit, it could be that the Twins are just very good/bad at hitting home runs, or their pitching staff if very good/bad at giving them up. Instead, one usually compares the total home runs that both the Twins and their opponents have hit at home vs the road.
If you look at it that way, Target Field is once again depressing home runs. Twins and their opponents have hit 115 home runs in Target Field but 127 on the road and they've played almost exactly the same number of games home and away.
