I just traded Zack for Carlos Quentin and 1st round pick in next supplemental. I thought my return was a little light but, I was I'm already leading my division in pitching, had a few injuries, and need some more offense. There also seems to be a glut of pitching. Very few teams in my league was looking to give up offense for pitching. And potentially I have greatly reduced any NL crossover problems at year end.
