Yeah, there's a few things I disagree with.
Corey Patterson just gets flat out fooled too often to be a top 10 hitter on any list except perhaps "top 10 CF on the Chicago Cubs." He's dangerous, but just has no concept of the strike zone. Everybody and their mothers know that he's going to get high heat with 2 strikes, yet he still swings and misses.
Justin Morneau, Jason Bay, and Joe Mauer should all be up a few spots, perhaps moving up at the expense of Patterson and Rollins.
Sean Burroughs and Clint Barmes? No, I don't think so. Rating Barmes this high is basing it on a small sample size. And Burroughs? The explanation by his picture on those rankings do nothing but criticize him. So why is he a top 20 young hitter?
