I'm not sure how it proves anything like that-anybody can be taught to take more walks at the expense of some of their hits. What San Diego is trying to do is instill plate discipline and make their hitters better, which I don't think this evidence has any proof for that at all. Edit: I do think plate discipline to a point is learned (some of it is natural, and some of it can be improved)-but this shows me very little except that they pushed their hitters to take more pitchers, which in a couple leagues caused high walks, high SO's, and very low AVG and SLG. That's not true at all. The high strike outs, low average, and slugging are independent of plate discipline. It shows how bad some of the players are in their system. Adam Dunn has high strikes, low average and great slugging. I'm not saying that plate discipline and those things are inextricably linked-they certainly aren't (one can have great AVG and great SLG and still have great plate discipline). I'm saying that the fact that those numbers are the way there are might suggest that the Padres hitters took more pitches simply to take more pitches, and found themselves down down in the count a great deal. There might have been such an emphasis on taking pitches that hitters were scared to go after the first few pitches, which led to either walks or being down 0-2 or 1-2-counts that are linked to high K rates and low AVG and SLG. It could come from the players in the Padres system as well, but that could be an explanation for those rates. Now-even if they are doing that, it may be a good long-term strategy. Teach the plate discipline and force people to watch plenty of pitches, and then slowly let them start attacking pitches that they now know are good pitches.
