Continuing to think about manufactured runs (from The Bill James Handbook) I found a strong correlation with SLG. Slugging average explains about 60% of what fraction of a teams runs are manufactured. Texas and Cleveland are the real outliers. So Indian ineptitude and Ron Washington probably explain the rest.
