With the end of the season nearing, it's time to look back at some of the best performances of the season in the minors. I want to apply the way scouts grade specific players' tools -- for the bigger fans of the prospect game, you're well acquainted with the 20-80 scouting scale -- for a prospect performance of the year-type vibe.
Here's the basic idea: Grade 50 is major league average for any given tool (fastball, hitting, fielding, etc.) and the scale runs three standard deviations up and down. One standard deviation is 10 points, thus 80 (the best grade) is three standard deviations better than a 50 (average).
