2011 baseball rookies.. Help?

I need some predictions.. And not just for fun. I am a collector of autographs and i've put together a collection of autographs from every rookie of the year winner from 1990 to present day. I'm trying to get a jump on this year's rookie class for both leagues.. Sometimes I get it right.. Sometimes I have to wait for the guy to win the award before I know whose autograph I need. Anybody got any rookie of the year predictions for this year? I've heard Kyle Drabeck and Desmond Jennings are popular choices for the AL.. And Aroldis Chapman is talked about alot in the NL. I know these are purely guesses but I like to get a jump on my collection.. Any suggestions or ringers anybody know about?
