This is because the runs per game numbers are tilted toward American League teams because of the designated hitter. You should adjust your rankings to account for the A.L. s designated hitter vs. the N.L. traditional pitcher-hitting rule. Not only do balls fly out of this place like space ships, but over the past three years the Rockies and their opponents have a .320 average in Denver vs. an on-road average of .257. Coors turns mediocre hitters into stars and ace pitchers into has-beens. I know, I know.
Balls fly out of left field and get lost in that white wall regularly, like at softball tourneys.
In fact, the 242 homers clubbed at Enron last year projects to 726 over three years, or 26 more than were hit at Coors between 1998-2000. Another field that favors lefthanded hitters, the Vet is not only a fairly good power park, but still has artificial turf, which helps boost averages. The Homer Dome, Baggie Dome or whatever you want to call it provides plenty of extra-base hits as well as good power numbers for lefties. The Jake boosts the Indians and their opponents average to .286 vs. .270 on the road. It also favors righthanded power.
