Every year around this time, all 30 teams in Major League Baseball send a group of prospects to Washington, DC for the Rookie Career Development Program. It's a four-day event for prospects which help prepares them for the next level, with everything covered from finances, to health, to handling the media. Now in it’s 27th year, the program is run by Major League Baseball and the MLB Players Association.
Each club will usually send 2-4 prospects each year. That means that not every player who is considered a prospect and is likely to make their MLB debut this year will attend.
