Another reason to trade him might be that if we get a starter, he's the piece that leaves the rotation. For example, if we trade for Peavy, and Buchholz comes back, what does our rotation look like? I initially had Doubront as the "prospect" I wanted to trade away for a real starter at the beginning of the season but now that Doubront has shown he can not suck, Workman becomes the odd man out imo. Sure, we can technically put him in the bullpen or stash him, but I think of the top 10-15 prospects, Workman/Brentz are the two I'd probably lose the least amount of sleep giving up in a trade.
