I know what you're saying, but there aren't many college, polished lefties in this draft. Marco Gonzalez and Ziomek are really the only two I can think of that might be available. Gonzalez has a good chance to go ahead of the Braves, though.
I'd also be curious to know Ziomek's sociability. There are some good pitching prospects at the top of this draft. Wonder if Corbin could convince him to come back for top 15 money next year
