The main job of a lead off hitter is to score runs. You are way too hung up on the OBP thing, but I'm going to try this again, anyway. DeRosa: 362 PA, 57 runs, .283 .377 .453, only 14 of his at bats have been higher than 5th in the order all year, so he's had bottom of the order guys hitting behind him most of the year. Theriot: 392 PA, 52 runs, .320 .394 .369, most his his at bats have come at the top of the order where Lee, Ramirez, Fukudome and Soto have hit behind him, yet with more plate appearances than DeRosa and a better OBP, he's scored much less. That's because he doesn't hit for power. DeRosa has twice as many XBH's than Theriot. Thus, DeRosa makes for a better top of the order hitter than Theriot. I'm not advocating DeRosa to hit 1st, just pointing out how DeRosa would actually be better in that role than Theriot. I have yet to see a box score where the winner of a game was decided by who got on base the most rather than who had the most runs. Those same scouts would probably say that Curtis Granderson, Jimmy Rollins and Grady Sizemore shouldn't be leading off, either. It's not just about getting on base. It's about getting in scoring position. Because Theriot is not good at getting himself in scoring position (poor XBH power and poor stolen base percentage), he is better off hitting towards the bottom of the order. Yesterday's game was a perfect example. Late in the game with runners on 1st and 2nd, the Cubs had Reed Johnson, Ryan Theriot and Mike Fontenot hitting with the game on the line. Hardly any power at all there. It sure would have been nice to have Soriano coming up (top of the order hitter) in that situation. It's also interesting that you drag Soriano's defense into the discussion. Why such venom towards a guy that has been very productive for the Cubs thus far? Theriot's defense nearly cost the Cubs the game on Saturday, yet he gets a free pass with you?
