Due to the amount of attention paid to each organization's top prospects and early-round draft picks, many of the game's underrated prospects are perpetually obscured. Most of the time, these prospects are younger players housed in the low minors who still require considerable physical projection and time to develop.

Lastly, I decided to filter out prospects that began the current season at or above the Double-A level, with exceptions being made for players who are 21 years of age or younger.
