The first-year player draft, also known as the Rule 4 draft, is Major League Baseball's primary mechanism for assigning amateur baseball players, from high schools, colleges, and other amateur baseball clubs, to its teams. The draft order is determined based on the previous season's standings, with the team possessing the worst record receiving the first pick. In addition, teams which lost free agents in the previous off-season may be awarded "compensatory" picks. The first amateur draft was held in 1965. Unlike most sports drafts, the first-year player draft is held mid-season, in June.
