A prospect is never a sure thing. While most top prospects in the top 10 range usually become, at the very least, a productive MLB player, that’s not always the case. One of the Pittsburgh Pirates forgotten outfielders in the late 2000s and heading into the 2010s was Lastings Milledge, and at one point, he was a top 10 prospect.
Now, Milledge wasn’t a top prospect with the Pittsburgh Pirates, but the New York Mets. He was drafted by the team in the 1st round of the 2003 draft, and appeared on his first top prospect list the following season, coming in at the 86th spot by Baseball America.
