I don't see Miller sniffing the big leagues until 2013. Maybe a Sept. callup this year if he makes progress with his secondary pitches. He has a great fastball but he relies on it too much.

Guys that could make a difference right away -
Jesus Montero - I do not think the move to Seattle hurts his stock at all. The fact that he's surrounded by a much less potent offense is easily outweighed by the fact that he'll get extra AB on the Mariners as opposed to the Yankees. I don't want to overhype him, but if you want to get excited, read some of the things Project Prospect said about him in their recent top 100 chat.
Bryce Harper - The Nationals have dropped hints that they're ready to hand him the keys to RF. Obviously this happens he can be an impact player right away.
Devin Mesoraco - now that Ramon Hernandez is gone, Mesoraco is going to get regular playing time. If it's a 50-50 split with Hannigan he won't have as much value to start the season, but he has the skills to make an early dent and be the full time starter.
Yonder Alonso - With Rizzo out of the way he has a clear path to playing time. Petco doesn't do him any favors, but there's a lot to like about his swing. Given the barren wasteland that is the NL 1B pool, he makes a very intriguing late round NL-only pick.
Matt Moore - I think enough has been written about him. Given his new contract it's almost assured he'll start the year in the rotation, and he could dominate right out of the gate.
Trevor Bauer - Decent shot to win a rotation spot out of spring training - he's definitely in the right league to thrive, and his high strikeout potential makes him look really exciting.
