I think it is going to be hard for Hazelbaker, 23, to get his shot with the club. He's definitely going to have to impress, with so many similar-aged OFs like Kalish (22), Lin (21), Reddick (23), and Westmoreland (20). That's a lot of low cost talent maturing at the same time.
As for Middlebrooks, he doesn't belong in that list for me becase I have little assurance that his natural talent would get him to the league. His upside is that if he fills out and his skills continue to develop as his body does, he could be an all-star. That variation is too much for me.
Doubront is probably the next player on my list:
8. Doubront
After that I see a lot of players who have the talent to contribute significantly at the MLB level, but who's skills aren't there yet:
Anderson, Reddick, Middlebrooks, Balcom-Miller, Younginer, Fuentes, Lin, Exposito, Renfroe, Lavarnway, Brentz.
