The Youngest Players In Each League

With Opening Day here, we are scrutinizing the rosters to see what are the must-see teams and what teams are hoping and waiting for some promotions. With that in mind, we also decided to look at who are the youngest players in each league. While being the youngest in a league does not always ensure that a player will be a successful big leaguer, it is a pretty good indicator that a prospect has a bright future–it's much easier to have a lengthy big league career if you reach Triple-A as a 21-year-old than it is if you break into Triple-A as a 27-year-old.

UPDATE: This list is now updated now that all of the Opening Day rosters have all been finalized. The youngest player in all of full season baseball is Phillies outfielder Domingo Santana. The Phillies' No. 10 prospect coming into the season, Santana, 17, is a full year younger than anyone else in full-season ball. It's worth nothing that the Carolina League (Salvador Perez) is the only leagues where the youngest player in the league is not ranked as a Top 10 prospect in that organization.
