Who’s The Youngest In Each League

Age isn't everything, but when you are talking about prospects, it means an awful lot. A 23-year-old tearing up the Midwest League isn't nearly as impressive as an 18-year-old who's managing to survive in the same league. With that in mind, here's a look at the 10 youngest players in each full-season league at the beginning of the season. In compiling this list, it's notable how few non-prospects populate this list–if an organization is willing to push you quickly to a level, it's usually a good sign for a player's potential.
