Every year after the minor league season ends, Baseball America announces a Top-20 prospects list for each minor league. The Cubs had five prospects named to these lists, all from the lower minor leagues.
These rankings are mostly based on conversations with the managers and coaches of each minor league. That’s slightly different from Baseball America’s rankings of the Top 30 prospects for each major league system, which weigh the opinions of scouts much more heavily.
To qualify for one of these lists, a player had to have played at least a third of that minor league team’s games in the previous season.
