Zach is up here because of A. Trevor Hoffman's compliment to his curveball and B. His stellar numbers for the last 2 years. He has a career 3.84 ERA and 171 career K's in 176 innings. He looks like another one of many pen arms soon to come out of our farm. He has a cieling of Brian Fuentes and could easily become Will Ohman 2.0, I see this kid in San Diego in under 2 years.
