Baseball America's League Top 20 lists are generated from consultations with scouts and league managers. To qualify for consideration, a player must have spent at least one-third of the season in a league. Position players must have one plate appearance for every league game. Pitchers must pitch 1/3 inning for every league game, and relievers have to have made at least 20 appearances in full-season leagues and 10 in short-season ones.
