I started to write an article yesterday about the youngest players in baseball, but discovered that someone already did the research for me. J.J. Cooper at Baseball America has a handy chart with a list of the Top 10 Youngest Players in each of the active baseball leagues, from the American and National Leagues down to the Low-A South Atlantic and Midwest Leagues. The chart is not behind the BA subscriber wall, so go take a look.
Some interesting nuggets derived from the Cooper's chart:
***As you know, Bryce Harper of the Washington Nationals is the youngest player in the major leagues. He is really, REALLY young.
Harper is younger than anyone in the Triple-A International League. He would be the second-youngest in the Triple-A Pacific Coast League, behind Rangers prospect Jurickson Profar and four months younger than Cardinals prospect Oscar Taveras. Harper is also younger than anyone in the Double-A Southern League. He would be the second-youngest in the Eastern League, and second-youngest (by one day) in the Texas League.
***Although this is his third year in A-ball, Delino DeShields Jr. is still the ninth-youngest player in the California League.
***It seems like Miguel Sano has been around forever since people have been talking about him for years, but the Twins prospect is still the youngest player in the Florida State League.
***The Cleveland Indians are pushing youth up the middle. Francisco Lindor is the second-youngest player in the Carolina League. Dorssys Paulino is the second-youngest in the Midwest League. Double-A Akron has three young infielders on the list: second baseman Jose Ramirez, shortstop Ronny Rodriguez, and third baseman Giovanny Urshela.
