Created a database with a bunch of info for each minor league in which the Rangers play, including:

5 youngest and oldest Rangers

10 youngest and 5 oldest players in the entire league

Comparisons of average age for every team in each league, and counts of players above and below particular age points.

A few players have moved (Hunter, Pina) since I updated the database, the there's still food for thought.
