A couple that give excellent position flexibility that will be available late in most drafts and won't bring big $ at an auction would be Robby Hammock of the D-Backs and Matt LeCroy of the Twins. Both are eligible as catchers (a big plus). Hammock is also eligible at 3B,CI,OF, & U in most leagues while Lecroy can be plugged in at 1B, CI, & U.
The nice thing about these two is their teams are trying to get them to the plate as much as possible. I haven't heard yet whether LeCroy is going to be the replacement for A.J. I have heard the Twins were looking for another catcher, but don't know if that is as a back-up to LeCroy or as an every day player. In the AL with the DH (Yuk)
LeCroy gets to bat every day any way. Hammock doesn't have that privilege. (He has to play real baseball)
Another I picked up late in one of the mocks who has some excellent potential is Chone Figgins. He will be eligible at OF, but check your league rules. He has 22 games as a MI. He does not have 15 appearances at either SS(8) or 2B(14), but combined has enough to be a MI(22). That would be something to look into before your draft. He had 13 SB in 240 AB last season. When he plays in the OF, he covers more ground than anyone I have seen in a long time. I didn't pay a lot of attention to his arm, but if Bernie Williams can continue to play OF in MLB, it obviously doesn't take much of an arm to play the position.
