First of all, I would choose Wood and Gordon w the first 2 picks. But let me assume you'll still pick Butler over Wood. Probably, someone better than Aybar will be available when you pick #7. Using the 7 players you listed, I would say Gordon, Kendrick and Kinsler are the most desirable. Let's say they get picked before you get a chance. That's leaves you w Verlander, Markakis, Maybin and Zumaya. I have all these players rated near Aybar, although all of them are a little lower. My choice between these players is not entirely clear. But A. Marte should also be available, since he wasnt even in the league last year. Also, how about Brian Anderson and J. Kubel? I probably would take any of those players over Aybar, altho w Kubel it depends on how healthy he turns out to be. So, if these 3 are available, I'd drop Aybar. If only 1 is available, maybe not because one of the owners ahead of you might select the one available. Of course, maybe you value pitching prospects higher than I do. If so, you probably would prefer Verlander to Aybar if available.
But depending on who's available, what I'd do might depend on your rules. Do you lose Aybar if he gets traded to the NL? If so, I might be more inclined to drop him because w the logjam the Angels have at MI he might get traded. If you dont lose him, then I might be inclined to keep him because I think he will steal a lot of bases w some team soon, maybe even this year.
Also, do you have your regular draft before your rookie draft? If so, Kinsler and Anderson probably will be taken in the regular draft. Maybe Verlander too, tho I doubt it. If so, I might be more inclined to keep Aybar. BTW, I seriously doubt Markakis will get any significant playing time this year unless someone gets hurt. Even then, they have other players they can turn to, like Fiorentino or Majewski.
