This gets quoted a million times with no proof or evidence. Bill James Link #-o I don't have a link. I read the books. Essentially, lineup order has a minimal effect on the total runs a lineup would score. The main concern, obviously, is having the right people in the lineup. Where they are positioned doesn't mean that much. Logically, you would want your better hitters toward the top of the order (and your worst hitters at the bottom) because the hitters at the top inevitably will get the most at bats, but over the course of the season, the order means little in terms of traditional ideas regarding lineup construction (i.e. having a "leadoff" guy, a "number 2" hitter, etc.).
