chris Carter - Oak. - Probably, although Eric Chavez is supposed to play first. Plus he is by far your best prospect, so I'd hang onto him.
Casper Wells - det. - Not likely. I think more likely impact year is 2011.
jordan brown - cleve. - ? - Two years in AAA, so probably. But not a great prospect. NA
brian dopirak - tor. - ? - 1/2 season in AAA, so might need more seasoning. NA
rhyne hughes - balt. - ? - 1/2 season in AAA, so might need more seasoning. NA
jordan danks - cws. - Not likely. I think more likely impact year is 2011.
chris petit - Ana. - Probably, but not a real strong prospect. NA
aex liddi - sea. - No. More like 2012.
cj retherford - cws. - Not likely. I think more likely impact year is 2011.
