Back to the original question, I think Duncan is a MUCH better pick up than Melky Cabrera. Duncan's power is for real and hitting in front of Pujols he'll see plenty of pitches. Just don't expect him to start every day. He only hit like .170 against lefties last year. However, he should do a lot more with his AB's than Melky will.
