I was wondering about him, is his walk problem something that has been noted before in the minors, or is it something that really just sprang up when he came up to the majors? I did some looking and found that he has a career minor league totals of 4.28 w/9, 8.14 k/9, 1.37 whip, which, while not good, is still not nearly as bad as the 13.50 w/9, 7.50 k/9, 2.67 whip. My thoughts are, and I have noticed this before, but have never tried to really compile stats on this, is that the Cubs management has a tendancy to be overly cautious in their approach to having a new, young pitcher out on the mound. They like the pitcher to try to nibble on the corners and not give up hits, to attempt to slowly gain confidence and not try to attack too much for fear of the big hit. I have seen this noticed in other places as well. I believe that some people have noted that this seems to have happened to Williams and now may be happening to Z, that the Cubs management has seen him struggling, and instead of having him attack the batters and throw strikes, they are having him be more cautious and throw more to the edge of the strike zone. Any thoughts?
