Each MLB team has four minor league levels that play full-season schedules, excluding Low-A and Rookie League ball, meaning that on any given day, there are 3,000 active players across the minor leagues.
So for a young player to rank as one of the 10 best prospects in all of baseball puts him in the 99.7th percentile among all minor league players.
In other words, if you're a top-10 prospect, you are fully expected to not only make an impact once you reach the big leagues, but to be a bona fide superstar and perennial All-Star-caliber performer.
The 10 players on the list that follows have incredibly bright futures and are expected to be impact performers. But are they all worthy of the high praise they have received to this point?
Each of these 10 guys has the potential to be great, and this is not meant to be a knock on any of them. What follows is my take on whether each of the top 10 prospects are under-hyped, properly hyped or over-hyped.
*Prospect rankings taken from B/R's Mike Rosenbaum's Post-Draft Top 50 Prospects article.
No. 3 prospect Gregory Polanco (PIT) not included after being called up to Pittsburgh.
No. 11 prospect Miguel Sano (MIN) not included after undergoing season-ending Tommy John surgery this spring.
