Jerry Crasnick has a good article on Brett Wallace on ESPN today.
An AL Scout:
"He stays in there against lefties and takes the ball the other way pretty well. But I think he needs to go back down to the minor leagues and tweak a few things. He'll probably do OK against No. 4 and 5 guys in rotations. But there are going to be nights when he faces 1, 2 and 3 starters and really looks overmatched."
Mike Barnett:
"For most guys, it takes 1,500 to 2,000 at-bats in the minor leagues before they're ready to play here and another 1,500 to 2,000 to get their feet on the ground at the major league level. To me, he's on a faster learning curve. Most young hitters are so hyped up they don't even remember what pitch they swung at. He can go pitch by pitch and tell you the whole at-bat."
