The Diamondbacks have traded much of their top talent from their farm system in deals for Dan Haren, Adam Dunn and Jon Rauch, but will replenish their system with nine picks in the first 70 to 75 selections of next year's amateur draft. The additional draft-pick compensation would come from the expected departures of Dunn, Orlando Hudson and relievers Brandon Lyon and Juan Cruz as free agents. The D-backs' concern that Dunn might accept salary arbitration is minimal. He is not yet 29,and headed for his fifth straight 40-homer season. In an era of decreased power, he should be in demand.
