Smoak's been in the majors for much of this season and hasn't hit much, but Baseball America had him as the 13th best prospect in baseball entering the season, which is considerably higher than they ranked Wilson Ramos. I can't tell you much offhand about the other three prospects, but Smoak's inclusion makes it a pretty rich package for a half-season rental.
At this point the Twins have to demonstrate that the players on hand are capable of contending.
