The Prospect Development Pipeline (PDP) is a collaborative effort between Major League Baseball and USA Baseball. The program's objective is to establish an official identification and player-development pathway for elite amateur baseball players eligible for the MLB Draft. The PDP was created in cooperation with the MLB Scouting Bureau, which oversees the athlete evaluations and files official player bios on all attendees.

To be eligible for a list, a player must have rookie eligibility. To qualify for rookie status, a player must not have exceeded 130 at-bats or 50 innings pitched in the Major Leagues, or accumulated more than 45 days on the active roster of a Major League club or clubs during the 25-player limit period, excluding time on the disabled list or in military service.

Eligibility guidelines are further determined by the Collective Bargaining Agreement, in terms of who falls under the international pool money rules: Players who are at least 25 years old and played in leagues deemed to be professional (Japan, Korea, Taiwan, Cuba) are not eligible.

Prospect Development Pipeline player profiles are generated by MLB Pipeline with the assistance of the MLB Scouting Bureau. The information herein is not associated with USA Baseball or Team USA.

Players are graded on a 20-80 scale for future tools -- 20-30 is well below average, 40 is below average, 50 is average, 60 is above average and 70-80 is well above average.
