our mid-season minor league draft

In my fantasy league, to help pass the down-time during the all-star break, we have a supplemental minor league draft.  We start the year with six minor leaguers (which could also include players from Japan, college/HS players, etc - anyone not signed to an NL-organization, since we are AL-only), then at the break, we can drop up to two of them (unless you already had some called up to the majors, in which case you wouldn't have to drop them) and get new ones.  My current "minor leaguers" are Wieters, Price, Moustakas, Smoak, Tabata, and Japanese player Yu Darvish.  (I don't want this to be a discussion on Darvish or Japanese players as a whole - let's just assume I'm holding on to him.)  Tim Beckham's not available, and remember we're AL-only, so which players from the draft would you take over any of the players on my list?  I'll probably drop Tabata for one of the top players in this year's draft (Hosmer, Matusz, GBeckham), but would you drop anyone else?  And would you drop Tabata for anyone other than those three?  And of course, whether or not a draftee signs with that team is also a consideration...

P.S.  There are a couple other actual minor leaguers who are still available that I'm considering, but since there are a couple guys in my league who read this, I'll not mention them :)
