MLB Pipeline's new Top 100 Prospects list will be unveiled to the world on Saturday night on MLB Network and MLB.com with an hour-long special at 8 p.m. ET. Many on the list could go on to become one of the greatest players in his organization's history. Others undoubtedly will not pan out.
Below is a look at the top-ranked prospect in each system over the past 15 years. This is a look at preseason list rankings, so some of the game's best prospects won't be listed here. And be sure the new rankings coming on Saturday will bring in some new names to this "best of" list a year from now.
