also, for those talking about Iglesias - he is 19. he is the SS of the future, but that is at least 2 years away (and that would be moving incredibly fast). I think that is why the team structured this deal with the 3rd year as an option. if Iglesias is ready, then good, he is ready, but if not, you have a little protection.
Lowrie looks like he could also be useful to this team, if he ever stays healthy. right now, he hasnt shown he can do that. I would think he will need to prove himself for a major portion of the season at AAA before the team even thinks about bringing him up
