There's been some debate over whether or not plate discipline is really "teachable" though, hasn't there? Certainly some tweaking can be done around the edges, but as far as I've gathered, the type of hitter you are is who you are going to be. (And has to do with all sorts of natural talents, eye-sight, swing style etc.) I dunno, obviously no one is expecting Javy to make huge changes in his approach and be a Ben Zobrist, I think whats encouraging for me is how much more contact he's making, because he's always going to be a hacker. Just gimme a Vlad Guerrero otherworldly type hacker, IMO.
