A while back I went through the hitting results for teams based on position in the order, trying to find a relationship to the scoring that teams did. I'm not totally sure how to interpret the data. The strongest correlation between lineup production and team scoring is at the 1st and 4th spots in the order. My theory is that, because the 1st spot will lead off at least once per game, and the 4th spot is guranteed to leadoff the 2nd inning in about 1/3 of all games (and then more or less randomly for the rest of the game), production in those two spots is more critical than elsewhere in the lineup. https://docs.google.com/file/d/0B5pIzP28qdp-WTZ5aHBJWHRRQ3c/edit?usp=sharing
