I don't like him much. he seems like a hacker with mild (20 HR) power for the majors as well as a mediocre average. Just one more solid yet nothing special type of future ML player to me.
Sean Tracey has my apologies, we all know Ozzie Guillen is an idiot. I'm rooting for you!
It's really hard to tell what to think of Duncan, a lot of it has to do with the Yanks themselves. They have rushed him at every step in the minors when he is a prospect that needed time to develope. So really while looking at his numbers they should be taken with a grain of salt, he is a better prospect then that. To try and project anything for him now is difficult due to his age & being rushed. I'd say a line of .260-.270 avg. w/ 20-30 HR power, would be around the best case scenario for him at the moment.
