MLB‘s most valuable commodity isn’t sluggers with prodigious power, innings-eating workhorses or flame-throwing relievers. It’s prospects, players in their teens and early 20s who have yet to establish themselves at the game’s highest level.

Teams are loathe to trade them, for prospects represent not only hope for the future but an inexpensive way to build a roster—at least in the short term. We need only look at recent success stories in Chicago, Kansas City and Pittsburgh for proof of that.
