In the dog days of Summer our fearless leader, John Sickels, underwent an annual tradition here at Minor League Ball. Every year he holds himself accountable for the Top 20 Prospect lists he releases before each season by reviewing his selections and seeing how they have fared. It's a great way to see who he was right about, who fell well below expectations, and to see the improvement of sleepers and breakout players.

You can find each team's review below, sorted by division. Just as a reminder, these are not new rankings. These are the pre-season prospect rankings but with comments from John on their 2015 performances.
