Ummm... I think the last time you looked at your prospects was in 2008. Or at least you were using a 2008 list when you drafted. All those guys have MLB service time to some degree, and most are no longer rookie eligible. In short, other than Smoak, they pretty much stink. I'd throw them all, but Smoak, back in and start over if you could.
For this year as far as last picks for hitters go, I wouldn't mind taking a shot on Kyle Parker, OF, Col., Randal Grichuk, OF, LAD, or Christian Yelich, 1B Fla. All of which fall outside of the top 75 prospects. That's assuming you have 8 MiLB keepers, not just 8 overall keepers. If you have 8 overall keepers, I wouldn't worry myself with the minor leagues at all.
