Prospects That Matter: Yellow
These players were selected based on a rating system that took into account their relative age, level, and performance, which was also adjusted by position and role (starter/reliever). You can read much about this here,here, and here.
(Update: July 23) These rosters reflect the mid-season PTM update for position players and starting pitchers.
(Update: August 1): Both James Ramsey and Zach Walters were included in PTM based on their performances in their old organizations
Prospects of Interest: Orange
These are players who didn't meet PTM for one reason or another but in my (subjective) mind worthy of interest to the casual fan. For instance, players who didn't meet Plate Appearance or Innings thresholds weren't included in the PTM ratings, and PTM didn't count short-season results.
