What does pr15 mean in fantasy baseball?

Answer 1

PR15 stands for "Player Rater 15." It is a rating system developed by ESPN that takes the player statistics in relevant fantasy statistical categories for the past 15 days, and compares them to the average player. A positive PR15 indicates that a player is above average, a negative rating indicates a player is below average. The 15 indicates that the statistics for the past 15 days are used.
