If one goes back over the last few years the Pittsburgh Pirates have seen their farm system go from one of the tops in baseball to more of a middle of the road organization. The main reason is that the team has seen a lot of their prospects graduate to the big league level. However, another reason is that the team has not had any real big, breakout prospects. The Pittsburgh Pirates really have not had one since Gregory Polanco burst onto the scene back in 2012 with the West Virginia Power.
Along with Polanco in 2012, infielder Alen Hanson also had a break out with the Pittsburgh Pirates affiliate the West Virginia Power.
