Unless KG knows things that other folks don't, most reports on Castro suggests that he has good enough discipline and an excellent eye. I haven't heard many people say that Castro is a wild hacker, and it certainly didn't seem that way to me. Could he stand to get better? Sure, but that report was off, IMO. Am I off on this? I really don't recall anything to suggest that we should be significantly worried about it. Perhaps this is a perception issue stemming from the AFL. It seems- at least the way I remember it- that Castro didn't walk much and was swinging early in the count during the AFL. Another possibility is that they've never seen him play, they look at his walk rate and wish it was higher. Since it's not they assume he must be a free swinger.
