Having the top farm system in baseball in no way guarantees success. Just ask the Royals, Pirates and Nationals, each of whom have had the top-ranked systems in past years but have failed to break free of their losing ways.
Still, it doesn't hurt to have a deep pool of talent. The Rays have used a constant flow of young talent to stay competitive in a division that thrives on free agency, while the Giants and Rangers have built a steady nucleus around players who were drafted, signed and developed by the organization.
There's no doubt that the Royals, Rays and Braves have a few of the top systems in baseball right now, but a few other teams near the top may surprise you (Oh, Canada!).
So, without further ado, I present the top farm systems in baseball, ranked worst to first.
