I for one am bearish on Walker's future. I've read multiple scouts from BP say that he has some pretty serious issues picking up spin and tracking breaking balls. Of course, the man can hit a fastball a country mile, but that alone will not guarantee MLB success. From everything I've gathered, it's difficult to improve pitch recognition skills significantly as you climb the ladder-- it's really more of a neurological thing. I'm not a professional, of course, but here's what Baseball Prospectus' Jeff Moore has to say about Walker after scouting him: "Jeff Moore: Saw a ton of Adam Brett Walker this year and he was one of my favorite players to watch. That's not an endorsement of him as a prospect. It's just because he gives exactly zero craps about trying to do anything other than hit a fastball as far as is humanly possible. He has great raw power, and I saw him square a few up and man were they fun to watch. I also saw him take the same aggressive swing and miss breaking balls by about 10 feet. Ultimately, I'm not sure the power ends up playing enough at higher levels because of the swing and miss and issues identifying breaking balls, but 25 home runs in the FSL is a major accomplishment. At the very least, he's fun to watch, and he has enough power that he could end up being a nice platoon bat." For what it's worth, Moore rated Walker's defense as league average in the future, 50/80 on the scouting scale. That's probably a little more insightful than what most of the posters here will tell you.
