What I have observed in the last ten/fifteen years in Houston is organizations that previously only had HS aged teams have expanded their age groups downward. Used to be many of the top HS "showcase" organizations started at 9th grade and the players came from Little League, Pony and other rec type leagues. As travel ball expanded to an earlier age, these organizations expanded their age groups to younger. Both to get players earlier ahead of their competition, and as a revenue stream.
I watched a once prominent travel org that had several major leaguers play for them, and many, many college players come through their system eventual fold because the coaches did not want to deal with the younger age kids (and probably most likely their parents). Josh Beckett, Matt Carpenter, Nathan Eovaldi and Brandon Belt all played for them in HS. On the positive side, many of their coaches still coach locally.
