I have Prado as a fill in guy until my starter comes back from DL and thats basically what he is. A fill in the hole player. He won't help you win in any offensive categories but he will just plug the hole and give you a 300 hitter. Zambrano followed up his horrifying first start with a much better 2nd start. Zambrano will be worth more at the years end to me where Prado is a great bat you can find on FA pool anytime.
