First of all there are no High A affiliates in Arizona. But you can have your new prospect's first exposure to regular season minor league baseball be 1 hour from Cincy, in one of the best facilities, with one of the best run minor league teams, with the best fan base in minor league baseball.
And you reward the fans and organization in Dayton, and make it possible for your Cincy fans to also see the new guy by driving up the road.
We just lost Chattanooga after a 20 year run, because the owner felt he was being mistreated by Reds ownership. Part of that was star players not being at their level for a while.
Since playing a month at Dayton, does not harm, and lots of benefits, that should be part of the working relationship with Dayton. Our top 3 picks will spend at least one month on Dayton roster.
