@fauxshawn Erlin's a starter. Peacock's a reliever. I'm wary of Erlin's stats so far, though - Myrtle Beach is a pitcher's paradise.
Hope he's wrong.

'13 for Erlin, Peacock could be this year in the pen, more likely '12. RT @fauxshawn: @keithlaw best case ETAs for both?
If things keep going well, I could see him pitching for the Nats in September, as well.
