Will a #1 pitcher emerge from the minors?

Nats See Pitching Growth On Farm - The Post
The Nats have some promising pitching prospects like Jordan Zimmermann. However, that may not be enough.Scouts tend to believe that Washington's system is flush with arms that might reach the majors, but almost none that will dominate there.I cannot get too concerned though. If the system develops five #3 starting pitchers, I would be ecstatic for a couple of reasons. One, five guys who win 12-15 games probably equals post-season. Two, the final piece of the puzzle, a dominant starter, could possibly come free agency. Three, that much pitching depth provides leverage to build the team through trades. So, hopefully the scouts are on to something here. more...
