*Zink walks way too many people right now. His knuckleballs are quality, but not consistent. If he nails that down, he'll be Wake Jr. If not, he'll be Steve Sparks. Yuck.
**Murphy has been hurt most of the season and hasn't hit a lick when he's in the line-up. He still has lots of major-league potential, but it's becoming less and less likely he reaches it.
***Cedeno throws the ball harder than a mofo, but he's got no control and no other pitches. He could be great, but he could suck balls too.
NOTE: The younger the player and the lower the level he plays at, the less likely it is for him to reach potential, especially for the non-college draftees. But, it is also more likely that they exceed expecations as well.
