Let's take a look at the O's minor leagues today.
I present Melewski's 2009 Orioles minor league All-Star team.
I didn't consider a player that made the Majors before August 31, eliminating players like Brian Matusz and Matt Wieters. I didn't consider players that played in fewer than 50 games, eliminating Josh Bell, among others, from consideration.
This isn't necessarily a listing of the best prospects, just those that had good years at those positions. For the outfield, I did not pick a left, center and right fielder, just three that played in the outfield this year.
